Swiss CNC, also known as Swiss-style lathe or Swiss-type turning, is a type of computer numerical control (CNC) lathe machine used in precision machining. It is designed to perform complex and high-precision machining operations on small parts with high accuracy and efficiency.

​

The Swiss CNC machine derives its name from its origin in Switzerland, where it was first developed for the watchmaking industry. The machine features a sliding headstock and guide bushing that support the workpiece close to the cutting tool, allowing for more precise and accurate machining. The machine also has multiple cutting tools that can work on the part simultaneously, reducing cycle times.

Swiss CNC machines are commonly used in the production of small, complex parts such as medical devices, aerospace components, and electronics. They are capable of machining a variety of materials, including plastics, metals, and composites, and can produce parts with tight tolerances and intricate geometries.
