Swiss type turning is a specialized CNC machining process that uses a sliding headstock and guide bushing to support the workpiece very close to the cutting tool. Originally developed in Switzerland in the late 1800s for manufacturing precision watch components, this method enables exceptional accuracy when machining small-diameter, long parts with tight tolerances and complex geometries. Today, it is widely used in medical device, aerospace, and defense manufacturing.
