CNC Turning

Our CNC turning process produces custom prototypes and end-use production parts in as fast as 1 day. We use a CNC lathe with live tooling so features like axial and radial holes, flats, grooves and slots can be machined.

CNC Turning design guidelines will help you understand capabilities and limitations.

Why Use CNC Turning For Your Project?

Proto Labs’ CNC machining service can deliver machined parts, in both plastic and metal, in less time than it takes to get a quote from other, more traditional machine shops. Upload a CAD file, choose the material and part quantity, and tell us when you need the parts. 

CNC material data sheets can be found in our Material Comparison Guide

How Does CNC Turning Work?

During the CNC turning process, a metal rod is rotated while a cutting tool is held against the stock to remove material and create final parts. The lathe rapidly machines your parts in a subtractive turning process with additional live tooling. Outside diameter (OD) and inside diameter (ID) threading is also available.

Turned parts can then be left as-machined, with visible tool marks, or bead blasted. When the run is complete, parts are inspected, boxed and shipped shortly thereafter.
