What is a Swiss Machine and How Does a Swiss Lathe Work?
Jun 02, 2021
A Swiss machine (Swiss CNC machine), also known as Swiss screw machine, Swiss lathe, Swiss automatic and sliding headstock lathe, which is developed in 19th century Switzerland, its initial function is to support the mass production of micro screws. Swiss type machines can achieve higher precision and accuracy than traditional lathes, especially when producing extremely small parts. On a traditional CNC turning lathe, the part is held firmly at one or both ends, and can only rotate in a fixed position, so the machine can only perform one operation at once, while with a Swiss lathe, the workpiece can both turn and move back and forth along the Z-axis, it can perform multiple operations at one time. The bar stock is feed through a guide bushing and tools are mounted to the face of the guide bushing, so the force is right where the material is emerging from the bushing, which minimizes the tool force effects of the part, then ensures greater precision. In addition, Swiss turning machines can not only manufacture turned parts but also applicable to the use of producing complex profiles without turned surfaces.
Benefits of Swiss Machining：
The piece is held steady in the position near the operation point and not affected by the force of tools, the precision can be maintained in tight tolerance.
Small parts with complex profiles and configurations can be manufactured, including thin walls, deep cuts, and more intricate features.
Because the Swiss machine can perform multiple operations at once, the production speed is much higher than common lathes.
Fewer needs for secondary processing and treatment, a shorter cycle of the production run.
