Precision Machined Shafts & Shafting for Equipment Manufacturers
A shaft looks like the simplest part on the drawing — a cylinder with features. But the shoulder that locates a bearing, the journal that runs in a bushing and the thread that sets preload decide whether the assembly runs true or wears out early. We supply precision machined shafts and precision shafting as complete shaft components — stepped, threaded and keyed — with the critical geometry measured before the parts ship.
Why equipment manufacturers choose our precision machined shafts
Features machined complete
Stepped diameters, shoulders, threads, keyways and cross-drillings in one flow — not split across three shops.
Geometry verified, not assumed
Critical diameters, runout and coaxiality measured on our Zeiss CMM for geometry and position, the TRIMOS V5 height gauge for heights and steps, and the AI-Vision system for fine features, with reports per batch.
Materials matched to duty
Stainless where corrosion rules, alloy steel where strength does, titanium and Invar where weight or expansion does.

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.
Turned and shaft work
Below are examples of this kind of work held to our standard tolerance and finish. Dimensions, drawings and material certificates are available on request.

What happens after you send your files
- Within 1 business day an engineer — not a salesperson — reviews your drawings and replies.
- DFM review: tolerances, material and risk flags, before any cutting begins.
- Your quote includes a material-verification plan: grade, EN/DIN check, certificate strategy.
Critical features are verified in house · material chemistry confirmed by spectrometer · EN 10204 3.1 certificates available.
