Swiss-type machining, also known as Swiss screw machining or Swiss turn machining, is a high-precision manufacturing technique used to produce small, complex parts with tight tolerances. It is named after the country of origin, Switzerland, where the technique was first developed in the late 19th century for producing precision watch parts. In Swiss-type machining, the workpiece is held in a collet and rotated while a cutting tool moves in the opposite direction along the length of the workpiece. The cutting tool is supported by a guide bushing that provides additional stability and helps to minimize deflection. This allows for very precise and consistent cuts to be made, even on very small and intricate parts. Swiss-type machining is often used in industries such as medical, automotive, aerospace, optics, and electronics, machine & equipment, where small, complex parts with high levels of precision are required.
