CNC Turning Services

Precision turned and mill-turn parts — shafts, fittings, connectors and bushings with runout you can measure, batch after batch.

CNC turned and milled components

Round parts, held to microns

Our turning department handles everything from 1 mm connectors to 600 mm flanges, in short runs and repeat production. Mill-turn machines combine turning, milling and drilling in one cycle, so features that used to need two operations arrive from one setup — with far better concentricity.

Every turned part is gauged on the floor with calibrated micrometers and bore gauges, and critical dimensions are verified on CMM for first articles and audits.

  • CNC turning with live tooling and mill-turn capability
  • Concentricity and runout held to 0.005 mm on critical parts
  • Threads, grooves, knurling and cross-holes in-cycle
  • Bar-fed production for repeat orders with first-article sign-off
