The original Swiss turning machines were developed to create the very small and precise parts required for Swiss watches. Known for their quality and precision, these watches require the most precise components to provide a smooth, even motion for the best and most accurate time keeping.
Today, with the use of CNC (Computer Numerical Control) the precision is enhanced, with the ability to create all parts perfectly to the original computer model. This type of cnc swiss turning is used in many different industries including the production of medical devices and implants, the development of parts for the aerospace industry as well as for military and defense contracts.
How it Works
With a CNC Swiss turning machine, the precision accuracy is possible because of the design differences found in this equipment over a standard CNC machining system. The Swiss turning center holds the tool stationary while the part is moved through the machine. The part is held very securely in place using the main spindle, a guide bushing and often a sub-spindle.
In this configuration, there is virtually no chatter or movement of the part or tool, allowing for precise and exacting milling and drilling. Additionally, and to further provide the precision required, the part is often made of ground bar stock or close tolerance bar stock, further reducing even the slightest in irregularities in the workpiece.
As the workpiece moves through the CNC Swiss turning machine, different live tools can be used to complete various milling as well as drilling requirements to the same precision. This will not only speed up the production of an individual part, but it also creates an identical part with each piece as it is all done on one machine.
Not every part requires this level of precision. Talk to your CNC machining contractor to determine if Swiss turning is the best option for your component production needs.
