Computer numerical control (CNC) Swiss turning is a precision machining process that employs a specialized Swiss-type lathe to produce intricate and detailed custom parts and components from stock material. Similar to the computer-controlled lathes used in conventional CNC machining operations, lathes for CNC Swiss turning operations employ computer programs that dictate the positioning and rotation of the workpiece along two axes against a single-point cutting tool.

CNC Swiss Turning

As the workpiece rotates, the machine tool shapes it into the desired shape and form. Although both CNC turning methods are suitable for reliably producing parts in prototype to short volume production runs, CNC Swiss turning is more accommodating of thin and long parts, while conventional CNC turning is better for thick and short parts.

At Buell Automatics, we offer CNC Swiss machining services for high-precision metal parts and components. Equipped with Citizen Swiss turning machines, our team can handle even the most intricate and complex part design.

CNC Swiss Turning Operations

Industry professionals employ both lathes and turning centers for CNC Swiss machining. Compared to traditional lathes, Swiss CNC lathes offer greater versatility as they allow machinists to produce higher precision parts:

  • Threading. Swiss CNC lathes enable threading to occur during the turning process, eliminating the need for a separate threading stage.
  • Facing. This operation trims the part to size and cleans the edges for a more polished finish.
  • Knurling. During the manufacture of tools, this process presses a pattern into the surface that facilitates gripping and handling.
  • Drilling, Boring, and Reaming. Similar to how they handle threading, turning centers save time by enabling manufacturers to complete these three processes in one step.

What Are the Benefits of CNC Swiss Machining?

CNC Swiss machining offers a number of benefits over other machining processes, such as:

  • Compared to manual turning: greater precision, versatility, and production efficiency, lower risk of human error and injury, and better repeatability/uniformity of parts
  • Compared to conventional CNC turning: better suitability for long and thin parts
  • Compared to CNC milling: accommodates cylindrical part designs with external AND internal features
