What is CNC turning?

CNC turning involves the application of a cutting lathe to a rotating blank workpiece in order to shape a desired part. During production, the workpiece spins on vertical or horizontal axes, while the automated lathe moves around it. Precise, repeatable, and scalable, CNC turning is ideal for creating parts with simple geometries and rounded or cylindrical shapes, as part of high volume production runs.


Begin your CNC turning project by uploading your CAD file to our Cloud Manufacturing Platform™. We’ll work with you to optimize your design and choose your material, and then take your project to production quickly and efficiently.
