Precision CNC Machining for High-Tech Equipment
ProtoTech machines precision components for robotics, automation, semiconductor, optical and inspection equipment manufacturers — from prototype and pre-series to recurring production, with every critical dimension verified in-house.
Why equipment manufacturers choose us
Engineering-led DFM review
Send drawings and get feedback on tolerances, materials and risk before any cutting begins — not after.
Advanced materials as standard
Kovar®, Permalloy, tungsten alloys, PEEK, PVDF, PTFE, carbon-fiber composites and more — handled daily, not exceptionally.
Verified, not estimated
Critical features are inspected in house; material chemistry is confirmed by spectrometer against EN/DIN grades.
Precision CNC Machining
Real capability windows — verified in-house, not estimated.

| Milling | 3-axis and simultaneous 5-axis machining centers |
| Turning | CNC turning Ø 2–65 mm, lengths to 300 mm |
| Swiss-type turning | Small diameters Ø 0.5–20 mm |
| Typical tolerance | ±0.005 mm typical (3-axis) · ±0.01 mm standard (simultaneous 5-axis) |
| Surface finish | Down to Ra 0.2 µm |
| Inspection | Zeiss CMM · benchtop material spectrometer · EN 10204 3.1 certificates |
| Prototype lead time | Typically 5–10 working days |
| Quantities | 1 pcs prototype to 1,000+ pcs/year recurring programs |
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.
