CNC Turning

With Computer Numerical Controlled Turning (CNC Turning) a metal, or plastic,  rod rotates at high speed while a cutting tool is held against the stock to remove surface materials and create the finished part. This process affords incredibly tight tolerances for exacting work.

We support turning of inside and outside features, and support most coarse and fine metric, inch, and NPT thread sizes. If needed, we can add thread relief grooves for manufacturing.

With turned parts, you can choose to leave them as-machined, which means the tool marks will remain visible, or you can opt for a smooth finish of varying types.

When the process is complete, we inspect all parts before boxing and shipping.
