What is a Swiss-Style CNC Machine?

» A specific type of lathe usually used to produce small precision parts.
» CNC = Computer numerical controlled Swiss type screw machines are more precise, and can produce more intricate parts
» Material is held in a bushing so the part is held close to the tools, allowing for more precise machining
» The defining characteristic of a Swiss-type lathe is a moving headstock that keeps the work piece supported near the point of tool contact » The resulting rigidity allows for higher cutting depths without sacrificing tool life or precision
