CNC Turning Service
CipherFab offers a high-quality CNC turning service for custom cylindrical, conical, and threaded metal and plastic components — from one-off prototypes to production runs — with instant quoting, DFM feedback on every upload, and lead times from 1 business day. Our CNC turning service uses CNC lathes and turning centres with optional live tooling to rotate the workpiece against a stationary or driven cutting tool, producing shafts, spindles, bushings, fittings, threaded fasteners, valve bodies, and rotational components to precise dimensional tolerances. Live tooling lathes add milled features — cross-holes, flats, keyways, and off-centre features — in a single setup, reducing lead time and improving dimensional consistency between turned and milled features. CipherFab provides instant quotes on CNC turned components with DFM feedback on every uploaded file.

Design Guide: CNC Turning
We have compiled our best tips into this guide to help you understand CNC turning processes, how to prepare your turned component drawings, design considerations for thread forms, bore tolerances and fits, undercuts, groove geometry, thin-wall turned components, live tooling feature access, and how to specify surface finish, thread class, and tolerance callouts effectively for turned components.
Advantages of CNC Turning
CNC turning is the most efficient process for producing cylindrical, conical, and threaded components — delivering superior surface finish, tighter bore tolerances, and faster cycle times than milling on rotational geometry. A turning operation produces a continuous, interrupted-free cut around the full circumference of the workpiece, generating Ra surface finishes of 3.2 µm or better as-turned and bore diameter tolerances to ±0.001″ as standard — performance that milling operations on cylindrical features cannot match without dedicated boring operations. Live tooling lathes allow milled features including cross-holes, flats, and keyways to be added in-cycle, eliminating secondary milling setups and the dimensional errors that accumulate when a component is re-fixtured between machines. CipherFab's CNC turning service covers the full material range from aluminium and brass through titanium and Inconel, with instant online pricing and DFM feedback on every upload.
