CNC turning with live tooling and sub-spindle capability.
Precision turning for shafts, bushings, housings, and rotational components. Live tooling and sub-spindle work allows complete part finishing in a single setup, reducing handling and improving concentricity.

FAQ
Engineering FAQs
The questions engineering and procurement teams ask most often before a first quote.
What's the difference between your CNC turning and Swiss turning?
Standard CNC turning handles parts up to about 12 in. diameter and longer lengths. Swiss turning is optimized for small-diameter precision parts (under ~20 mm bar) with tight concentricity.
Can you mill features on turned parts?
Yes — the Mazak QT 250MSY has live tooling and a sub-spindle, allowing drilling, milling, and cross-features in a single setup.
What surface finishes can you hold?
Surface finish is process- and feature-dependent. Specific Ra targets are reviewed during quoting; secondary finishing operations are available when tighter finishes are required.
Do you support production turning programs?
Yes. Repeat OEM programs run with documented setups, controlled tooling, and SPC on request.
