What is Swiss Screw Machining?

Swiss screw machining is a subtractive manufacturing process utilizing Swiss-type machining equipment. Learn more below!


Swiss screw machining utilizes a Swiss-type lathe designed to produce parts repetitively from a 12-foot or 3-meter-long bar. Unlike a conventional lathe, the Swiss screw machine has a sliding headstock that creates the Z-axis motion while the bar is supported with a guide bushing positioned in front of the turning tools. With this arrangement, machine operators can turn long diameters with superior precision.


CNC Swiss screw machines are versatile and used for producing components for almost every industry at any diameter. These machines create parts up to 32mm or 1 ¼”, making them uniquely effective in machining extremely small microwork.
