Precision CNC Turning for Round Components
Round components carry rotating equipment — and tolerances matter more the faster it spins. We turn precision components from Ø 2–65 mm with full material traceability and dimensional reporting on every critical feature.
Why equipment manufacturers choose us
Round parts, round-the-clock control
Diameter, concentricity and surface finish are inspected, not assumed — Zeiss CMM reports on critical features.
Material you can trust
EN 10204 3.1 certificates plus spectrometer verification of incoming stock chemistry.
Prototype to production
From one-off prototypes to recurring 1,000+ pcs/year programs with stable, documented processes.

Materials we machine
From Drawing to Delivered Part
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Submit & Review
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
Quote & Material Plan
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
Machine & Inspect
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Deliver & Support
Kitted, ESD-safe or ISO Class 7 cleanroom packaging, with local engineering and after-sales support through our German partner.
Parts we have made
Photographs of parts machined at our Shenzhen plant. Send us your drawing and we will confirm the process route for parts like these.
