How CNC Turning Works

CNC turning operations may seem complex, but the process can be simplified. Once you convert your CAD files into a program that the CNC machine can understand, you're ready to set up the machine and start turning.

In turning, the workpiece rotates while a cutting tool removes material from the outer surface. Typically, the material being machined is cylindrical or round, although turning can work with different shapes using the right adapter.

As the workpiece spins, the cutting tool keeps making cuts until the programmed shape is achieved. CNC lathes or turning centers have a turret with various tools controlled by computer programs and codes. More advanced machines can hold multiple tools, offering greater capabilities for complex designs.

CNC Turning FAQs

  • What is a CNC Turning Center?

    A CNC turning center, also known as a CNC lathe or a CNC turning machine, is a type of machine tool used for the process of CNC turning. It combines the functionalities of a lathe and a computer numerical control (CNC) system to perform precise and automated machining operations on cylindrical workpieces.

  • What is the difference between rough turning and finish turning?

    Rough turning removes as much material as possible without a focus on accuracy and surface finish, getting the workpiece close to the desired shape. Finish turning “finishes” the process, producing the desired smoothness and accuracy.

  • What are the typical applications of CNC turning?

    CNC turning is a versatile machining process used in various industries and applications including automotive, electronics, aerospace, firearm manufacturing, sporting, and others.

  • What are the types of turning operations?

    CNC turning operations encompass a variety of techniques and processes used to shape and machine workpieces on a CNC lathe. Here are some common types of CNC turning operations: facing, external turning, internal turning, taper turning, thread cutting, knurling and grooving.

  • What parts can be made with CNC turning?

    CNC turning is used for creating a variety of parts, including auto parts, knobs, tubes, gears, toy parts, flywheels, crankshafts, hubs & disc cams.

  • What minimum thickness can I incorporate into my design to prevent warpage?

    Typically, we recommend a minimum wall thickness of 0.5mm for metals and 1mm for plastics. However, these values largely depend on the size of the part; therefore the larger the part size, the higher the recommended minimum wall thickness should be. Please keep in mind that this does not imply that wall thicknesses with lesser values are unachievable.
