Ep. 63 – Running a Machine Shop like a Tech Company with David Wynn

By Noah Graff

Today’s Swarfcast is part one of an interview we did with David Wynn, CFO of ABF Engineering and Machining, a third generation screw machine shop in South Fulton, Tennessee. After earning an MBA, David joined his family’s business 17 years ago. His stated mission is to run a machining business composed of old cam screw machines as though it were a tech company.

Main Points of the Interview

(2:40) Dave gives a history of ABF Engineering and Machining. The business was started by his grandparents and father in 1976. They primarily ran Brown & Sharpe screw machines.

(4:45) Dave talks about the machines in his shop. He said the company has Haas lathes, CNC Swiss, and a CNC mill, but still more than 50 percent of the company’s work is done on Brown & Sharpe screw machines. The company is running 15 Brown & Sharpes currently, but Dave says he has about 100 in the building.

(6:30) Dave gives a brief education about Brown & Sharpes. He says what makes Brown & Sharpes productive is that an operator can work with the turret and other tools simultaneously. The machines are extremely rigid, and have a gear driven 5Hp motor.

(12:47) Dave explains how building a cam for a Brown & Sharpe screw machine is similar to writing a CNC program for a Swiss machine. The main difference is the CNC program is immediately implemented while the cam takes days to build.

(14:45) Dave talks about how he came into the business. He had never stepped foot in the shop before he turned 18 years old. While in college and grad school he began working at the company. He earned an MBA, but instead of going into the finance industry he fell in love with the machining business and decided to do it full time.

(18:40) Dave talks about how ABF Engineering and Machining changed after he and his father bought it from his grandfather. He says they chose to focus on creating a new culture based on teamwork and innovative work practices. They prefer to hire people who fit into the company’s culture rather than hire based on an applicant’s talent.

(21:55) Dave talks about the company’s unconventional practices for work hours. Its employees have the flexibility to work when they like and choose how many hours they work as long as they get their work done and work as a team. He says that most outsiders look at him like he is a space alien when he tells them about some of his policies.

(28:40) Dave says that usually the people who are most successful at his company are the ones who put in a lot of hours at the shop and also at home. One of the characteristics he looks for in a great employee is someone who is constantly trying to better herself.

Question: Do you know how to run a Browne and Sharpe?

    First, to answer your question, yes, I’ve run a few Brownies in my life.
    David is absolutely right on his analysis of why Brown and Sharpe machines are the fastest single spindle screw machines available. It’s the overlapping of tools.
    The killer today is finding enough skilled people to run them. Many companies are not training new people (largely because no one wants to learn) on these older machines.Most of the people who know what to do with these machines are my age (old) or older.
    There are CNC options out there that are viable for longer cycle time parts, but if you can drop parts off complete on a Brownie in under 15 seconds, no CNC machines can compete.
    Great job Noah and Dave.

    This is a great interview. I can’t wait to hear the rest of it. I can relate to how Dave runs his operation like a tech company. Allowing flexibility does make for a happier work force. I also liked what he said about hiring based on a cultural fit. Often times I think to hire a pro but personalities and cultural adaptation seem to over rule that especially when you’re trying to establish a team based organization.
    P.S.
    I cut my teeth on Swiss cam machines and ultimately migrated to CNC Swiss. Along the way I did buy a Browne and Sharpe and ran a few jobs on it. Ultimately it didn’t fit into my line of business and eventually sold it. Although, I’m still fascinated with Swiss cam machines and have a few in storage.
    One last thing…..Dave is right: a set of cams is just like a CNC program!
