Our CNC turning service produces most cylindrical and conical shaped parts on the CNC lathes. CNC Turning is a machining process in which material bar is held by a chuck and rotated while a cutting tool is fed to the piece to remove material to create the expected shapes, our live tooling is available for more complex parts and produced on a single machine for axial, radial holes, flats, grooves, and slots as fast as 1 day.

How Does CNC Turning Work?

CNC turning a machining process that used to make cylindrical parts, during the CNC turning process, a metal or plastic rod is rotated while a cutting tool is held against the stock to remove material and create final parts. The lathe rapidly processes your parts in a subtractive turning process with additional live tooling. There are four different types of turning, straight turning, profiling turning, taper turning and external grooving.

A center with both turning and milling capabilities can stop rotation to allow for milling out of other shapes. Turning parts on CNC turning centers allows for a wide range of sizes, material types and complexities.

The starting material can be round, square or hexagonal-shaped.

CNC with live tooling can stop rotation to add additional features like drilled holes, slots and milled surfaces.

The tools in CNC lathes or turning centers are digitally controlled.

Some CNC turning centers allow work to be completed on both sides by employing an additional spindle.

CNC turning centers vary in tooling and spindle options, as well as outer diameter (OD) limitations.

These processes produce various shapes such as straight, curved, conical, or grooved workpiece. Turning parts can be left as-machined, with visible tool marks, or bead blasting. When the process is complete, parts are inspected, packed and shipped shortly.
