Precision Turned Components
Our core craft — CNC and Traub turning to ±0.01 mm.
Overview
This is the capability Rajhans was founded on: take a customer drawing, set up a CNC or Traub machine, and hold the print — diameter, concentricity, thread and finish — across a hundred thousand parts.
We machine free-cutting brass, stainless and mild steel from Ø3 to Ø65 mm bar, with in-process inspection at the machine and final inspection on calibrated instruments. If your part spins on a lathe, it belongs here.
Typical Applications
- Electrical and electronic terminals
- Instrumentation and metering parts
- Pneumatic and hydraulic components
- Fasteners and special hardware
- Any made-to-print turned part
