I know you will enjoy this favorite past episode, whether or not it’s your first time hearing it.
As Swiss machines continue to improve, so does the capability of the accessories and tooling to aid you in the machining process. This episode will hopefully illuminate some ways you can improve your efficiency and accuracy by adding modern technology to your current machines.
Our guest is Jim Gosselin, owner and President of Genevieve Swiss Industries. Genevieve Swiss sells innovative accessories specifically for Swiss CNC lathes, such as live tooling and cutting tools, to combat the problems small parts manufacturers constantly deal with.

Jim gives an overview of Genevieve Swiss. He says the company’s mission is to make the job of the machinists easier. If machinists have the right tools to get better efficiency and quicker setups, then machining companies will be more profitable. (2:30)
Jim says he was always interested in mechanical stuff from a young age. He liked to take apart his toys as a kid to try to understand how things worked. He dropped out of high school in his Junior year and went into the military where he became a combat engineer. He summarized that job as “building things and blowing things up.” (3:00)
After getting out of the military, Jim got a GED and took college courses at night. He worked at a machining company called Savage Arms in Westfield, Massachusetts, that made shotguns and other hunting equipment. In 1983 he became a programer and ran the new Citizen CNC machines that the company purchased. The machines had 2 turrets with 5 stations each, with cross drilling and milling capability. He says those machines were not actually sliding headstock. Rather, they were sliding guide bushing machines. The turret and the guide bushing slid together on the machines. (4:00)
In 1987 Jim became an applications engineer and salesperson at Brookdale Associates, a Citizen distributor in New England. In the late 1980s Brookdale Associates began building high pressure coolant systems for Swiss machines. He says before then, high pressure pumps were not used for Swiss turning. The company also sold a line of accessories, including tool holders for Swiss machines. In 2002, he and his colleagues traveled to Switzerland where they began a relationship with PCM, a company that sold high quality live tools. Jim thought that Brookdale would distribute PCM’s tooling, but it was a difficult year for the machining industry, so his boss didn’t want the risk of taking on a new product line. He told Jim if he wanted to start his own company he supported the idea and would be his best customer. That was the start of Genevieve Swiss. (5:45)
Jim says that when he started Genevieve Swiss he realized at the time that many Swiss operators were getting older and they were burning out because the Swiss machining process caused too many headaches. He decided his company’s mission would be to make Swiss machinists’ lives easier by supplying them with products that enable faster setups and better cycle times. (8:00)
Jim talks about developing gear-driven head live tools for Swiss machines with PCM. He says that prior to gear-driven live tools, typically live tools on CNC Swiss machines turned at 4000-5000 RPM for cross drilling or cross milling. He says this wasn’t efficient for end-mills that could be as small as a diameter of .020” or .030”. The slower turning speeds caused burrs and slower cycle times. The new gear-driven heads produced 3 times the output as the older technology. (9:25)
Jim talks about the products Genevieve Swiss sells. The company sells accessories specifically for Swiss machines such as live tools and cutting tools. It sells arbors for slitting as well as coolant that is specifically designed for high pressure delivery. He talks about a thread whirling head for a Citizen L20 that is designed to have coolant flow right through the head and then delivered to the cutters. (see video above) (10:30)
Jim says that chip control problems are one of the most significant hurdles for Swiss operators. He says often in medical work that uses difficult metals like 465 stainless, chips can come off the machine like ribbons. Genevieve Swiss is working with its insert tooling supplier UTILIS to sell laser ground chip breakers. (see demonstration video below) (12:40)
Jim talks about insert tooling developed by UTILIS in which coolant flows through the tool and is focused on the tool tip. (17:00)
Jim says most of the Genevieve Swiss’ innovations come from listening to customers on the shop floor. He says the company talks to customers and distributors to find out what machining problems operators are complaining about. (20:00)
Jim compares the construction of older Swiss CNC machines to those of today. He says that Swiss machines used to have heavier castings to achieve rigidity. While today’s Swiss machines are built with lighter castings, Jim says they are designed more intelligently based on factors such as stress analysis, which enables them to stay ridged. (21:30)
Jim says the incorporation of lasers is one of the most interesting recent innovations on Swiss machines. Lasers can do cutting, milling, cross drilling, and knurling. They also enable welding two parts together while still on the machine. He says though 3D printing is slow right now, it could be a disruptor in small parts manufacturing one day. He brings up a scenario of a Swiss machine that also incorporates 3D printing. (22:30)
