Ep. 113 – A MultiSwiss Screw Machine to Maximize Production, with John Belmonte

By Noah Graff

On today’s podcast we continue our series about Swiss machining. Our guest is John Belmonte, owner and President of Mitotec, a precision turning company in Necedah, Wisconsin.

Recently Mitotec purchased a Tornos MultiSwiss 8X26 multi-spindle screw machine. The unique design of the MultiSwiss enables such quick changeovers the machine is running many of the same jobs the company has on its single spindle Swiss machines, but in a fraction of the cycle time.

Main Points

John gives an overview of Mitotec Precision. The company is located in Necedah, Wisconsin. It features Tsugami Swiss machines, Miyano CNC lathes, cam multi-spindle Tornos SAS16s, Tornos DECOs, and recently purchased a Tornos MultiSwiss 8X26, a 26mm 8-spindle CNC multi-spindle. (3:00)

John tells the story of Mitotec Precision. The company was started by John’s grandfather in 1963 in Necedah, Wisconsin, and originally was called Necedah Screw Machine Products. John says the company changed the name in 2018 because it was using newer technology than just cam screw machines. It wanted customers to understand that it had become a CNC Swiss shop. Also, the company changed the name to help recruit young talent—people interested in working with sophisticated technology, rather than only cam screw machines. (4:10)

John Belamonte with the Tornos MultiSwiss 8×26

Mike says while growing up he worked at his family’s shop in the summers but didn’t always think he would go into the business later in life. He was interested in studying to be a lawyer but eventually realized that he didn’t have the grades to go in that direction, so he returned to Necedah to work in the business. Over the years he has had lots of jobs at the company. He started on the shop floor, which at the time mainly featured Brown & Sharpe screw machines. His learned estimating from his grandfather, and then he gravitated toward screw machine engineering. (5:50)

John says the first CNC machines the company bought were CNC Brown & Sharpes. Then it bought Miyano CNC lathes, and then Swiss machines starting with Tornos DECOs. (7:20)

John says the company produces a lot of parts for the medical industry, as well as electrical components and firearm components. He tells Noah about a medical part made on Miyanos that goes into a system to inoculate people in Africa without using a needle. (8:50)

John says the company tries to “make parts that matter.” He says it’s good for his team to feel they are making parts that make life better for people. He says if employees know how important the company’s parts are they will make sure they are high quality. (9:45) 

John says that making medical parts is a good place to be in manufacturing. He says Mitotec Precision is constantly trying to use its expertise in machining to improve the parts for its customers. (11:00)

John explains how the Tornos MultiSwiss works. The machine has eight spindles that move in and out like a Swiss machine, however they don’t have guide bushings. The company decided it needed more capacity, but rather than buy a lot more Swiss machines, it decided to buy a CNC multi-spindle to cut cycle times. Even though there were only around 20 8X26 MultiSwiss machines in the United States, Mitotec chose that machine over an INDEX CNC multi-spindle because the MultiSwiss has a design that makes it quick and easy to change over. Unlike many companies that buy CNC multi-spindles for long runs, Mitotec wanted a machine to do a lot of short runs. The company’s goal is to be able to change over jobs on the MultiSwiss in the same amount of time it would take on a conventional Swiss machine. He says the company can make many parts on the MultiSwiss 3-5 times faster than on a traditional CNC Swiss lathe. For example, he says he can take a complex part that takes 90 seconds on one of his Tsugamis and produce it in 10-15 seconds on the MultiSwiss. This means he needs fewer machine operators because one machine could be running the same work as several machines. (13:00)

John talks about how the company has changed its organization in the last several years, implementing a management system called EOS. The company sets strategic 10-year goals, 3-year goals, and annual goals. In the new organization he has a senior leadership team that meets weekly, consisting of himself as the integrator, an engineering manager, an ops manager, sales manager, and HR. He says the new organization has had great results. (20:00)

John says another change the company has made in recent years is that it is not afraid to let go of certain customers if they they are not profitable or good to work with. (23:30)

John says when he hears the word “happiness” he thinks of being with family. He also says for him it means getting to do something every day that makes him want to get up in the morning. He says he likes being a good leader, getting to solve complex problems that matter, and having a great team around him. (24:20)

John says to create a good company culture, first a person has to define his core values. He says some of Mitotec’s core values are creativity, drive, adaptability, reliability, and thoroughness. (25:30)

John says it is usually necessary for Mitotec to train its own employees because it is hard to find good people already experienced in machining. He says people in his area of central Wisconsin generally have a good work ethic. Mitotec tries to get the interest of young people in the area by going into middle schools and high schools to expose them to oportunites to work in manufacturing that uses modern technology. He says there are some young people in the area who leave to see what life is like in big cities, but often they come back because they like life in smaller Wisconsin towns and feel it is a good place to raise a family. (26:15)

Noah asks John what he learned last week. John says he learned that the company had such a great year in 2020 it was now going to distribute a significant profit-sharing contribution to its employees. (29:30)

A Typical Tuesday for a Machinery Dealer

By Noah Graff

Yesterday, I started my workday by returning a phone call to customer in Italy as soon as I finished my home workout. I had read their email to try to distract myself while doing wall squats.

Later I spoke with people in Czech Republic, Germany, California, Arizona, Michigan, Wisconsin, and New York, and emailed others in Ohio, Pennsylvania, Illinois, Albania, and probably other places. Most of the people were making parts or peddling iron like myself.

Customers often ask me how Graff-Pinkert’s used machinery business is doing, and they ask me how I think the manufacturing economy is doing. After all, I’m in contact with manufacturers worldwide, and of course, I’m “the journalist.”

It’s hard to make generalizations about the machining world’s ecosystem. The majority of customers tell me business is at least stable. Many say they made money in 2020 or at least held their own. When they gush about their success in 2020 I always joke to them, “damn, I’m in the wrong business!”

Anecdotes from customers are more useful barometers for gaging the state of the machining economy than looking at the day to day events of our own business. I’m sure my fellow dealers will attest that the business is a rollercoaster because of it’s illiquidity. There could be no cash flow for weeks, and all of a sudden three big deals happen in a day. Suddenly the economy must be on an upswing!

Noah Graff in the Graff-Pinkert shop

You have to be very patient if you’re a used machinery dealer. My dad likes to say that often deals are like fruit, you just have to wait for them to ripen before they are ready to harvest—sometimes years! God willing, yesterday we finally sold two beautiful CNC multi-spindles that have been ripening in our warehouse for several years. They were built in Germany, traveled to Spain, then to Texas, then to Chicago, and now if all goes well they will go back to the place they started from. I hope I’m not jinxing the deal by writing this. Until we have received compensation for them, it’s not a sale.

Right now we have three multi-spindles, almost as old as me, ready to ship Mexico. Two other multi-spindles, older than me, we are hoping will go to Australia. There’s also a sweet Swiss machine I hope is bound for Europe.  

We have a tool and cutter grinder that we are quoting to companies in China, Mexico, the United States, Spain, Brazil and Turkey, and the supposed value seems to fluctuate dramatically from country to country—and not exactly how one would predict. We don’t know what the sell price should be. It’s constant internal debate.

That was my Tuesday (leaving out quite a few details). I think the day gave me a decent survey of the international turned parts industry. I’ll reiterate, it’s important to listen to a lot of different people to get a feel for the industry. I can’t go by what one person says because I hear so many diverse views. I can’t totally trust my own business’s day to day vibe either because, I, like everyone, live in my own bubble. Lots of our customers say business is great right now, and as I write this, 5-10 good deals seem like they are on the verge of breaking. But right when I think I understand something, or a deal seems great, or a deal is about to happen, or a deal is going flop, or my favorite ice-cream shop will have the flavor I’ve been waiting for, things take a turn in an unexpected direction—not necessarily a bad one though.

One more thing. Shameless self-promotion–the Doosan TT1800SY in this blog’s email blast ad is a real find. You won’t find treasure like this on your typical Wednesday!

Question: How do you feel the machining economy is doing?

Lessons from the Pandemic

By Lloyd Graff

I spent several hours working at the Graff-Pinkert office today for the first time since last April. 

I am beginning the process of coming out of my fear induced hibernation, three weeks after my first COVID-19 vaccine shot. The statistics say I have 80% immunity after one Moderna vaccine hit. I sort of trust the number, but not enough to do without the mask, which is my constant annoyance when I leave my home. 

I hate the COVID necessitated hibernation. At my age, with a heart attack and heart surgery in my past, I am still COVID’s emotional captive. I know I am vulnerable, even if only one in 200 of those who catch the illness die of it. 

I have learned from my COVID home prison sentence. I’ve learned that I can happily do without many of the appointments I thought were necessary. 

I can officially forget about going to the barber. I used to be a customer at a little suburban shop run by a woman who seemed to find me irritating because I came by irregularly and liked Saturday morning appointments. She cut my hair in 14 minutes, so I was easily sandwiched in, but she told me she had no appointments one too many times, so I decided to try the barbers at a local Meijer supermarket. They were okay, but I have learned that I can successfully cut my own hair and shave my neck without any barber. The pandemic teaches us what we can do without.

I have also learned that I can live without visiting the dentist every three months for a cleaning. It was more about cleaning out my bank account than a necessity. Semi-annually or yearly will do quite fine from now on.

Lloyd Graff in the Graff-Pinkert shop

My relationship with my work has changed over the past year. I have found that it is unnecessary for me to be at my office much of the time, and I am happy to not be there every day. But working at home I almost never turn off my work channel. There is always another email, another blog, another call to make. 

When I go to work physically I am much more likely to walk around, to connect with people in the plant, to ask questions. Working from home is more iPad-based, less face-to-face connection. I get the news and the numbers, but I miss the vibe. I am more distant, and it has to be noticed.

I find that the longer I am away, the harder it is to come in. COVID-19 is the rationale, but the reality is that I could mask up if I really wanted to go in. I cannot put a financial value on this, but I know it is real. 

Last year was a down year financially for our machinery business. Everybody in the company made less money than in 2019. Two full-time employees were let go. 

This year appears to have much more activity from all over the world, yet COVID-19 limits our willingness to travel and inhibits our customers’ travel. This hampers our ability to close deals. We have to trust other people to inspect machines without us. Our network is extensive, but it does not make up for physical movement completely. 

What have I learned?

I have learned that I love the business and I never want to quit unless my health forces me to do it. I have learned that I don’t have to be at the office a lot but I cannot be a phantom. I have learned that it helps to physically travel to close deals.

I believe that the worst of the pandemic is now behind us. Now is the time to really push to harvest the good times coming. 

Risa and I are taking our second Moderna shot in a few days. After waiting two weeks for maximum immunity, we are going to take off in a plane to California to see family. 

Questions:

Are you going to be vaccinated?

Will you make changes in your lifestyle after getting vaccinated?

Best of Swarfcast Ep. 31 – Ken Mandile, Employees Are Buying His Business

By Noah and Lloyd Graff

We’re currently working on fresh new episodes of Swarfcast. In the meantime, we felt this “Best of” was fitting for the recent season on CNC Swiss machining. 

In March of 2019, we interviewed Ken Mandile, founder of Swissturn, a successful CNC Swiss machine shop in Oxford, Massachusetts. Ken’s children are not interested in taking over Swissturn when he eventually retires, so five years ago Ken began restructuring his company into an employee stock ownership plan or ESOP, in which he will gradually transfer ownership and management to his employees.

Main Points

Before going the ESOP route Ken turned down two lucrative buyout offers from private equity firms. Ken reported that after the first year of restructuring as an ESOP, the value of the company increased by 51%.

Ep. 112 Developing a World-Class CNC Turning Company with Mike Reader

By Noah Graff

Today’s podcast is the fourth episode of our season interviewing people involved in CNC Swiss machining.

Our guest is Mike Reader, owner and president of Precision Plus, a CNC turning company in Elkhorn, Wisconsin. Mike came into the machining business at 31 years old following a career in the fast paced finance industry. When he first arrived, the company was using old school Tornos cam Swiss machines and running a lot of commodity-type parts. Over the years Mike has built a world-class machining company, diversifying the company’s product lines with the help of newer technology. All the while, his original cam Swiss machines still keep spitting out parts.

Scroll down to read more and listen to the podcast, or listen with Google Podcasts, Apple Podcasts or your favorite app.

 

Main Points

Mike gives an overview of Precision Plus. The company has 30 CNC Swiss machines, 40 older Tornos Cam Swiss machines, and some Miyano CNC lathes (single, double and triple turret). Mike says he has diversified the company’s clientele over the years. Precision Plus focuses on medical/dental, aerospace, and a variety of products in the industrial sectors. He says he has purposefully stayed away from doing automotive work because in his past experiences those clients were not looking for “a win for both sides.” (3:15)

Mike talks about being interested mechanical stuff when he was growing up in Delavan, Wisconsin. He says he was always the kid in the garage trying to make the go-cart go faster—the adrenaline guy. In high school he did well in technical classes as well as the standard curriculum. (4:45)

With encouragement from his guidance counselors he went to University of Wisconsin, Madison, where he majored in Economics with an emphasis in finance. After graduating he went to Chicago to get into the commodity futures world, starting out as a runner at the Mercantile Exchange and Chicago Board of Trade. Eventually he moved up to working in clearing operations and then got a job at Bank of America running their clearing operations. He says that world was intense and competitive—a lot of “work hard play hard” 80-hour weeks. (6:00)

Mike talks about using the Predictive Index Personality Assessment to organize his workforce at Precision Plus. He gives the assessment to employees in order find the correct spot to put people in to be successful. He also talks about the importance of pushing his people on the shop floor to keep stretching themselves. He likes to make his people strive to figure out how to do things better, faster, and smarter. He says if he ever gets to a point when he is no longer doing that, it will mean the business is in decline. (8:00)

Mike says when he first started managing he wanted to hire people who reminded him of himself. He says we all think instinctively that others should think the same way we do, but he learned from the Predictive Index tool that people don’t all think the same and they don’t all hear the same. His says the first time he looked for employees his instinct was to look for the pedigree of the “best and the brightest,” but that was difficult because college graduates often don’t want to start their careers working in Elkhorn, Wisconsin. They want to go off and see the world like he did. Later, Mike changed his criteria for new employees. He started looking for smart, driven people who wanted to get to work right out of high school, in addition to graduates of technical colleges and 4-year universities. (9:50)

Mike says Precision Plus often likes employees who are trained in-house, so they learn to to things the way company prefers. It also helps create a good company culture. (11:15)

Mike tells the story of moving his family to London to work for Bank of America and then coming back home to Wisconsin only 10 months later when his mother was diagnosed with cancer. His father had bought Precision Plus only seven years before but had to go care for Mike’s mom. All of a sudden at 31 years old Mike was thrust into running a machine shop, which at the time was still pretty rough around the edges. It was a dark oily screw machine house in 1995—no CNC lathes, only Tornos mechanical Swiss machines and secondary equipment. (12:15)

Mike says when he first got started at Precision Plus he looked at the customer portfolio and could see that the company had a lot of opportunities to grow. At the time the company was doing a lot of brass connector pins on Tornos cam Swiss machines. (15:40)

Mike says that he really enjoyed working in the commodity futures arena in the first chapter of his life. He says the last 25 years in manufacturing have been meaningful for him. He talks about how in the early 2000s a lot of companies sold out American manufacturing to make greater margins by making parts overseas. At that point he realized that the had to move up market. He saw that the company needed to get into more highly engineered products than simple connector pins. He said it gave him purpose to keep manufacturing in the United States and create rewarding, good careers for Americans. (17:00)

Mike talks about the parts that go into musical instruments which Precision Plus produces. He says the company has been making parts for that customer since before he arrived at the company. They make screws and arbors that go into oboes, bassoons, and piccolos. (19:00)

Noah asks Mike what he thinks of when he hears the word “happiness.” Mike says it means being successful and being in control of your destiny. He says its important to him that Precision Plus is a private company where he has the freedom to make the decisions that are best for the company. (20:30)

Mike says the key to future growth for Precision Plus is continuing to increase the complexity of the parts it produces, setting it apart from other companies making more commodity-type parts. He says the way to accomplish this is by investing in better machines and pushing his people to keep upping their game. (21:20)

Mike talks about the roles of his various machines. He says there are no bad machine tools, just bad applications of machine tools. He says the Tornos cam Swiss machines are still a good solution for lower complexity parts with tight tolerances. For more complex parts Precision Plus uses Miyano CNC lathes. He holds up an aerospace parts the company makes complete on a triple turret machine, which he says had 98 different features on the print. (See video below). He says the shop also features many Tsugami and Star CNC Swiss machines that produce great parts and have great support. (22:15)

Mike says Precision Plus is interested in acquiring another machining company if he can find the right fit. He would prefer to buy a turning company not doing automotive work located in the Midwest because he likes the work ethic that the Midwest is known for. Also it would be best if the company can also add to Precision Plus’s current capabilities. (25:40)

Mike says the thing that bothers him the most running a machining company is that not everyone sees the world as he does, and he can’t stand missed opportunities. He says the most important thing is for people to work to the best their abilities, with a positive attitude, no matter what they are tasked with. (26:35)

Question: What do you think of when you hear the word “happiness?”

Ep. 111 – Producing Tiny Parts on Swiss with Dan Rudolph

By Noah Graff

On today’s podcast we continue our season about Swiss machining. Our guest is Dan Rudolph, co-owner and founder of Rudolph LLC. Rudolph LLC produces medical parts as small as .1 millimeter on Citizen lathes. The company has only three staff members, Dan, his wife, and his father, but Dan says he has no plans to hire employees and the company continues to grow. 

Scroll down to read more and listen to the podcast, or listen with Google Podcasts, Apple Podcasts or your favorite app.

 

Dan describes Rudolph LLC. The company produces medical device components particularly for eye surgery. It manufactures mainly stainless steel and titanium components on Citizen Swiss lathes. The company has eight machines and plans on adding several next year. It also has various secondary and finishing equipment, as well as Universal Robots. (3:00)

Dan says when the company started he and his father gravitated toward smaller parts that required smaller sized equipment. They had no employees, and the company started in a 900-square-foot shop. Now it has a second 900-square-foot room available for machinery, and a second floor for finishing equipment. (3:50)

Dan talks about his career path. Growing up, his father was a supervisor for a Swiss department at an eye surgery OEM. In the evenings he ran a small foundry that did brass castings. Dan often tagged along with his father to the foundry as a kid. He attended Penn State for industrial engineering and worked in foundries after college, but decided that career path wasn’t what he was looking for. He and his dad had been talking about starting a medical Swiss shop together for a while because his father had knowledge of the industry and good contacts from his former company. Dan says since he was young he had an affinity for the elements involved in running CNC Swiss machines—a lot of moving parts, math, and computer programming. (5:30)

Dan says his dad prefers a supervisory role as well as handling quality and secondary operations, while he loves running production and setting up machines. (9:45)

Dan says the smallest part Rudolph LLC runs is .1 millimeter. The company does a lot of work with thin-walled parts (.002” thick). They drill holes as small as .007” in diameter in stainless or titanium. (10:40)

Dan says often he sees working on small parts as “imagining a half inch part but in a smaller world.” Though, he says often with very small parts the bar stock can break off in production. He says when he is working on very small parts he breaks up the work. He will turn a few features and then stop the machine to see what’s going on. Sometimes he will program the sub-spindle to grab the part just to make sure he can find it. He says when the parts are in the sub-spindle you sometimes have to use a razor blade and fish them out. He says for a lot of the parts after the sub-spindle picks them off he opens the collet and then an air blower puts them into jars or tubes. Then he evaluates them using a vision system or other measuring system. (11:30)

Dan says Rudolph LLC’s shop is located on what used to be a farm. The barn has been replaced by two 900-square-foot garage-type buildings. The company started in one of the garages and then when it grew took over the second garage and connected the two. Then they built second a floor on top. His father’s house is located across the driveway from shop. (14:30)

Dan talks about his wife leaving her CPA job to join he and his dad at the company. She has been shadowing Dan’s father so she can eventually take over his role as he gets closer to retirement. (16:00)

Noah asks Dan, how he can “replace himself?” What happens if he needs to step away from the business for some reason, or go on vacation? (17:45) 

Dan says when he and his dad founded the company they decided they didn’t want to be “people managers.” He jokes that people at other shops warned them against the complications and headaches that come with hiring a lot of employees. He says that he and his dad prefer doing the actual production work. Automating with Universal Robots for secondary operations and Swiss machining that can finish an entire part enable the company to function and thrive without requiring extra manpower. He says in 2021 the company is not taking on new customers and instead trying to improve the work it does currently. (18:45)

Dan says one of the main things he wants to improve upon is reducing the rough edges on parts. He wants them cleaner with less burrs and loose material. Increasing his quality consistency will mean spending less time at the microscope troubleshooting. (22:15)

Dan Rudolph of Rudolph LLC

Noah asks how Dan how he is able to come up with new ideas and solutions if he is continuously busy producing parts. Dan says being spread thin is a constant obstacle, but even so, he and his father do not want to hire help. He says if they can perfect the work themselves they won’t need to hire anybody. He says his wife has been a huge addition to the company because she knows how he thinks, so she can help solve problems without creating a new problem of people management. She takes on some of the work, which has smoothed out the operations such as shipping and running the Universal Robots. (22:50)

Noah asks Dan if he has advice for someone else who wants to start small shop similar to his. Dan says he can’t fathom starting a shop without at least one other person because with two people you can divide the work between your strengths and weaknesses. (25:15)

Dan says he sees his company’s mindset as a game to see how much he and his dad can do within their constraints. He says having limited space is advantageous because walking around a big shop takes time. (26:00) 

Dan says something interesting he learned last week was his research on various ways he can renovate his home’s deck. He says he has spent time searching on Instagram for photos of work done by contractors. (28:00) 

Dan says social networking on Instagram has been beneficial for him. It has given him a peer group of other people in the machining world, which he lacks in his own 3-person company. He says his Rudolph LLC has even gotten some customers from Instagram. (29:30)

A Black Woman’s Job Title

By Lloyd Graff

Rosalind Brewer took the helm at Walgreens this week, becoming one of only a few African American woman CEOs to ever lead a large American corporation. She had been #2 at Starbucks before being recruited by Walgreens. 

I wasn’t surprised to see a black woman get a top job with a company like Walgreens. It would have been more shocking if a black woman’s small machining firm applied for membership in the Precision Machined Products Association (PMPA), an organization I belong to as a technical member. 

This is not a putdown of the PMPA, which I am happy to be a member of. It is an observation about my America, where women have generally been outsiders in manufacturing, engineering and metals, both by culture and by prejudice for as long as I can remember.

Perhaps the scene is changing, with Mary Barra now heading GM, but an African-American woman running a machining outfit with 25 employees in America is something I would love to see in my lifetime.

New CEO of Walgreens, Rosalind Brewer

****

As I talk to clients and people in the industry, I’m getting the strong impression that business is perking up. While the media is obsessed with COVID-19, empty malls, and evictions, the shortage of people who want to take manufacturing jobs gets even more acute. 

Even in fossil fuels, which we all know are yesterday, the US is still pumping 11 million barrels of oil a day and importing the black gold from Canada too. Farm prices are up, which means tractors are finally selling, and car lots are short of inventory.

Home sales are allegedly frantic, at least in the suburbs, and new home builders are having their best years ever.

It’s all a bit bewildering as the Washington politicians lament the worst economy since the Depression and are bargaining the difference between $600 billion and $1.6 trillion to dump into the economy.

The stock market has given its verdict. Buy, buy, buy. The Fed has made its call to keep interest rates low. Bank losses have been a fraction of what had been expected to this point.

It must be the time to book a cruise for this summer.

The least recognized vital aspect of health is posture. I don’t know how the chimpanzees and gorillas live like they do, but a bent over Lloyd is a miserable mammal.

The last year has been brutal on my body. I have been home for much of the time, from Groundhog Day to Groundhog Day, and it feels like perpetual winter. During this period, I have made the kitchen table my workspace, and my neck has been almost continually bent as I navigate the phone and iPad to write. My spine feels like a defective erector set. I look like a FANUC robot. I might be turning FANUC yellow as well.

My neck and shoulders are tight as 2-year-old unopened pickle jars. I keep fiddling with the thermostat because the compression of my shoulders and neck and rib cage gives me the chills. 

I tried to throw a snowball the other day and it landed 12 feet from me. I am a sorry heap. 

But, I now have placed three foam rollers strategically around the house, and I’m starting to feel like bread dough. The rolling is beginning to work. My pain is six Advils less a day. I have fewer groans when I hit the bed. The chills are fading. My stretches have some elasticity. 

Why, oh why, didn’t I start the bread dough a year ago?

Question: What are your back pain remedies?

Ep. 110 – Citizen Mad Scientist, Chris Armstrong

By Noah Graff

Today’s show is the second episode in our season about Swiss machining.

I interviewed Chris Armstrong last week while he was parked at a rest stop somewhere in Texas. He was en route on an all day trip to service a customer’s Citizens. I met Chris and his partner, Ryan Madsen, owners of Texas Swiss, a few years ago, trying to sell them some Citizen L20s from Asia.

Texas Swiss, formerly named Mad Science, is a CNC Swiss job shop not far from Houston that focuses primarily on Oil & Gas and Defense, along with some medical and other work thrown in. Chris told me that some of the medical parts the company produces actually have similarities with gun parts because of their size and various other features and shapes.

Scroll down to read more and listen to the podcast, or listen with Google Podcasts,Apple Podcasts or your favorite app.

 

 

In the past, I’ve usually talked to Ryan when peddling machines because Chris always seemed to be on the road, servicing the machines of other shops. That puzzled me, but eventually it became clear that servicing machines is truly a second business for their company. Just cranking out parts isn’t enough for Chris because his true passion is wrenching on machines. 

Chris’s Citizen odyssey began 15 years ago. He was 21 years old and had just gotten laid off of his job as a welder at a fab shop. The night he lost his job and the following day he let off steam by blaring Metallica and starting a rehab on his condo’s bathroom. His neighbors in the building complained about the noise. When Chris explained to them that he was pissed off about losing his job one of the neighbors suggested he visit her son’s machine shop the next day. 

Chris Armstrong of Texas Swiss

When Chris came to the shop he laid eyes on a 1993 Citizen L316, and it was love at first sight. The machine was a new addition to the shop because the company was bringing new work in-house, so nobody there knew how to run it yet. Chris seized the unclaimed position of operating the shop’s lone Swiss machine. He taught himself to run it, taking books home at night and memorizing them. He was the beginning of the company’s Swiss department. The company, which was a medical shop, grew exponentially the next few years, but Chris eventually left to work for Citizen. He traveled around doing applications, sales, and support for awhile before finally deciding to start his own Swiss shop. Eventually he teamed up with Ryan Madsen, a high school friend to start their company Mad Science (later renamed Texas Swiss). The company’s original name came from Chris’s nickname, “Mad Scientist,” which he was given when he learned to operate a Matsuura MX-520 in one legendary morning on his own.

Chris says he enjoys the “crime scene forensics” element of troubleshooting machines. Yet, he says the root of most problems he encounters in shops comes from simplest of culprits. He says a lot of problems occur just because machines are not kept clean. Stray swarf and chips can easily cause a chain reaction of production mishaps.

He also says machines often don’t work correctly because they were poorly set up. He says setup people are sometimes in such a hurry to get a job up and running they use the wrong tooling, which is the cause of a lot of machining issues. He told me he likes to say “slow is smooth, smooth is fast.” His philosophy is that the machines are already plenty fast, so taking a little more time for a setup will make production a lot more efficient in the end. He adds, its always important check machines’ sleeves because they’re always suspect. 

Just talking to Chris a few minutes you know he can’t be content with staying home running a production shop, never venturing out into the field. He told me it would be a waste of a God given gift for him not to service machine tools, and that helping people overcome their machining heartaches and bring their projects to life gives him purpose.

Ep. 109 – Citizen CNC Swiss Lathes with Marc Klecka

By Noah Graff

Today’s show is the first episode of our new season about Swiss-Type CNC machining. Our guest is Marc Klecka, founder and president of Concentric Corporation, a prominent distributor of Citizen-Cincom CNC Swiss lathes in Cleveland, Ohio.

Main Points

Marc talks about his company, Concentric, which has been distributing Citizen Swiss machines for 31 years and Miyano for 10 years (after Citizen acquired the company). (2:20)

Marc gives his “5-year-old explanation” of Swiss CNC Machining (sliding headstock machining). He says the original technology of “Swiss style machining” was developed in Switzerland over a hundred years ago for producing high precision watch components. He says what differentiates CNC Swiss machining from conventional CNC turning is that a CNC Swiss machine grips the part with a collet and also supports the part with a guide bushing. This eliminates the vibration that normally occurs when machining bar on a a conventional CNC lathe. (3:00)

Marc says a traditional Swiss part has a length to diameter ratio of 3 to 1 or more because that is the point where you start sacrificing the rigidity and accuracy on a conventional CNC lathe. He tells a story about a Citizen customer who produced a 10-foot part out of aluminum tubing. (4:40)

Marc talks about the importance of running ground bar stock on Swiss machines, particularly for running lights-out. However, he says that says in the 31-year history of Concentric, he estimates that only 30% of the material run (in Swiss mode) on the machines he has sold has been ground bar stock. He says it is a misconception that Swiss Style CNC machines are only good for running ground stock. (7:25)

Marc says that during 2020 Concentric’s business did ok, but the pandemic made it more difficult to sell machines because it was harder to have in person contact with customers. (11:00)


Marc says that there are lots of good brands of machine tools on the market, but he sees the support and service of local distributors as something that sets Citizen apart. He says that many years ago Marubeni Citizen made a point of having all of its local distributors become self-sufficient for servicing customers. He says that all the Citizen sales engineers also are applications engineers. He says it is important to have sales people who can get in the trenches with customers to solve their problems. (12:00)

Marc talks about Citizen’s proprietary LFV (low frequency vibration) technology, which is featured in many of the latest models. It enables operators to control the geometry of the chip coming off the machine using the machine’s CNC control. He says this capability is significant for manufacturers who want to do lightly attended or unattended machining. (17:20)

Marc talks about the significance of the medical sector for Citizen machines. He explains thread whirling for making long bone screws. He discusses a bone screw that was made on a Citizen featuring a laser that performed a cut on that part while still inside the machine (see video). (21:45)

Marc talks about diverse markets where he sees Citizens being used. He says during COVID-19 woodworking has become more popular and Citizen machines are making tools used for the art. Also, he says tattoos have become more popular during the pandemic and Citizen machines are making parts that go into the tattoo gun pens. He says demand continues to grow for parts for the electric car markets. (26:00)

Noah asks Marc tell him something he learned the week before. Marc jokes hat he learned it probably was not a great thing to break into the Capital building. He also said that he learned about the new LNS chip conveyors that are being put on some of the newest Citizen machines equipped with LFV technology. (31:00)

A Battery of Questions

By Lloyd Graff

Every few months it’s fun to write a piece that asks, “what if most of the smart people are wrong?”

I just read a fascinating article in the Wall Street Journal discussing the $50 billion bet Volkswagen has placed on developing an electric car that is better than a Tesla. Should we be surprised that the best German Engineers, who built the diesel that nobody bought (at least in America) and then lied about its numbers, would build an electric car that wouldn’t work? 

VW has now brought in new people, shoved the boss aside except for window dressing, and started over. 

This was all predictable. It takes a crazy lone wolf like Elon Musk to pull off a viable electric car that can sell a half a million vehicles and satisfy a fairly high percentage of them. Musk has shown he can make an Electric, but to me he has not shown that there is a real mass demand for it, at least he did not in the year 2020. 

I do think quite a few Electrics will sell in China because Chairman Xi is going to force them down people’s throats, but excuse me for being heretical, I don’t think most folks care whether a car has a plug or a gas cap, or floats on hydrogen. They want to get from one place to another, safely and comfortably. They either do not care or accept the concept that an electric car, which is really fueled by coal, natural gas, or God forbid a nuclear power plant, will save the planet from the climate change that “smart people” tell them is happening.

Another surprise for you, fewer and fewer people care about cars and driving these days. I suggest you discuss this with your kids and grandchildren who are supposedly aching for these software engineering masterpieces. When I was 16, everybody begged to get a driver’s license on their birthday. Today many young people would rather ride their bikes.

I think Elon Musk already knows this. This is why he is hedging his bets by focusing on his batteries, spaceships, and tunnels to Las Vegas and Austin.

Volkswagen ID.4 Electric Vehicle

He has built a car for people to brag about, and he has become the richest person in the world by doing it, which may enable him to live on Mars until he is 140. Vehicle companies will sell 90 to 100 million things you use for transportation. Musk’s 500,000 electric cars along with what everybody else is producing have a puny 1% of the market. Now Google, Apple, and possibly the Vatican are working on Electrics because everybody knows they are the next big thing. Except, maybe they aren’t. 

I watched a lot of football over the weekend. One insipid car and pickup truck commercial after another was followed by 797 car insurance advertisements. Liberty, Liberty, Liberty, Liberty, Liberty. Please free me from them or I will Progressively lose 15% of my cerebral cortex. 

There is a reason for the proliferation of GEICOs–the reduction in real driving. COVID and Zoom have diminished driving for almost a year. As a result, fewer accidents. State Farm has crushed it. Post-vaccine, people will still be working more remotely. Driving will shrivel. You can finish the story. 

I will place my bet that Earth will survive despite the “Existential Threat” of sweat. 

Enjoy your self-driving electric Volkswagen. I think I’ll walk.

Question: Does a Hybrid car make more sense?
