Swiss Screw Machining Process

Swiss screw machining was first designed for Swiss watchmaking and developed over time to accommodate aircraft, technology, and medical industries. Swiss screw machining differs from regular machining by using subtractive manufacturing that employs a guide bushing to maintain a closer distance between the main spindle and the cutting tool.

This process is often used to make precise cylindrical parts and products quickly and efficiently. This unique type of machining produces the kind of perfection that keeps machines with a compact design running smoothly with limited downtime, while performing multiple operations simultaneously, much like the Swiss originally intended.

Swiss Screw Machine Advantages


The operation time of a Swiss machine is much lower than its lathe counterpart. A Swiss machine can perform several operations at once with a combination of tools all working together to reduce wait times.


With this type of machining, there may be no need to grind or for extra finishing. The surface finish will be perfectly consistent, with a higher quality finish, every time.


Little operator involvement is required because a Swiss screw machine can run autonomously. The machine contains multiple spindles and cutting tools, helping optimize production, and limit labor costs.    


With the integration of CNC technology, manufacturers are enabled to achieve tighter tolerances with a lower chance of production error.
