CNC Turning Services: From Shafts to High-Volume Precision
CNC turning services produce round, concentric parts—shafts, bushings, fittings, and threaded components—by spinning the workpiece against a stationary tool. It is the fastest, most economical route to high-volume cylindrical precision, and with Swiss-style sliding-headstock lathes it scales down to tiny, complex diameters. This guide covers when to turn, which materials, and how to brief a shop for clean, repeatable results.
Turning vs. Milling: Which One?
CNC turning excels at round features—ODs, IDs, tapers, and threads—in one setup. CNC milling owns prismatic and pocketed shapes. Many parts need both; our Swiss turning cells handle small, complex, high-volume diameters with extreme precision and built-in milling.
Materials We Turn
- Aluminum alloys — fast, clean, easy to finish.
- Stainless and carbon steels — structural and corrosion-resistant.
- Brass and copper — electrical and decorative.
- Titanium and Inconel — with tooling optimized for hard alloys.
Tolerances and Finishing
Standard ±0.05 mm, tighter on critical diameters. Roundness and finish are improved with cylindrical grinding and centerless grinding, and edges are cleaned by deburring. Threads, grooves, and cross-holes are cut in the same cycle.
Prototype to Production
Because there is no tooling, the same program scales from one shaft to millions. For higher volumes, features can shift to forging or powder metallurgy—our rapid prototyping team bridges the two.
How to Spec a Turning Job
- Send a STEP/IGES model and a 2D drawing with critical diameters and datums.
- State quantity and lead time to choose lathe type and fixturing.
- Define finish and coating—anodize, plate, or passivate—up front.
- Request DFM feedback to cut cost before turning starts.
FAQ
Swiss or conventional lathe?
Swiss for small, long, tight-tolerance diameters; conventional for larger parts.
Can you hold tight roundness?
Yes—grinding and lapping push roundness well within microns.
What file do I send?
A 3D model plus a 2D drawing with critical dimensions called out.
