Conventional CNC Turning vs. Swiss CNC Turning
Swiss turning and traditional Computer Numerical Control (CNC) turning are two different ways used to machine parts made of metal or other raw materials. Specifically, machining is the process of removing material from a workpiece and shape it into its intended design. Both Swiss turning and CNC turning function by spinning materials at high speed and using cutting tools to shape the material into the desired part. This practice has been around for many years but has become more versatile with new technologies. These practices are crucial to many different industries for their ability to engineer metal and plastic parts efficiently and precisely.
In this post, we will give you information regarding:
- Conventional CNC turning what it is, how it can be applied, and why it is useful
- Swiss CNC turning what it is, how it can be applied, and why it is useful
- Comparative advantages: what these processes have in common and how they are useful to your industry
- Which type to use how the advantages of these practices apply to you
What Is Conventional CNC turning?
Conventional CNC Turning is a process in which the bar stock rotates in a fixed position and the cutting tool’s position is driven by servo-controlled motors, typically in the X and Z axes. The process allows for highly accurate movements. Commercial metalworking machines feature standard closed-loop controls that provide accuracy, speed, and durability.
Advantages and Features of Conventional CNC Turning:
This type of conventional turning is better suited for shorter, large-diameter parts with tight tolerances or difficult materials. It is ideal for many applications including:
- Bar Stock
- Sawed Slugs
- Anything with a diameter larger than ¾ inch
What Is Swiss CNC turning?
Swiss CNC turning is a process that feeds rotating bar stock through a guide bushing. No matter how long the workpiece, the turning tool always cuts the stock near the bushing or the point of support. The machine then feeds this past the spindle and past the tool as it goes, making Swiss-type effective for long and slender turned parts.
Advantages and Features of Swiss CNC Turning
Swiss CNC turning has an advantage in that during the turning process, the material is supported close to the tools cutting it. Using a guide bushing, the workpiece is pushed through and into tools while preventing deflection of the workpiece.
Some ideal applications for Swiss screw machining are:
- Long parts and small-diameter parts under 0.750 in.
- Connector components
- Watch parts
- Metal devices and implants

Which Turning Process Should I Use?
If you need something with minimal bending or your project has high volumes of small, cylindrical pieces with extremely tight tolerances, then Swiss CNC turning would be the best process for you. On the other hand, Conventional CNC turning offers high repeatability, precision, versatility, and speed manufacturing.
