Carbon Fiber Machining for Lightweight Precision Structures

Carbon fiber composites offer stiffness metals cannot match at a fraction of the weight — and they punish careless machining with delamination and fiber pull-out. CFRP is abrasive, anisotropic and unforgiving; the pay-off is parts that are light, stiff and stable.

Why ProtoTech

Why equipment manufacturers choose us

Delamination is the enemy — we plan for it

Tool-path strategy, sharp composite tooling and support backing keep edges clean and laminates intact.

Abrasive material, managed tool wear

CFRP destroys standard tooling; our parameters and tool choices are set for composite work.

Light, stiff, stable parts

Fixtures, robot components and structural elements where metal would be heavy or resonant.

How we work

From Drawing to Delivered Part

A transparent, engineering-led process built for long-term supply programs — not one-off transactions.

1

Submit & Review

Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.

2

Quote & Material Plan

You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.

3

Machine & Inspect

In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.

4

Deliver & Support

Kitted, ESD-safe or cleanroom packaging, with local engineering and after-sales support through our German partner.

FAQ

Frequently asked questions

Delamination — layers separating at edges, holes or pockets. Controlled tool paths, sharp composite-specific tooling and backing support are how we keep laminates intact.
Yes — we profile, drill and machine laminates and tubes to print. Layup and fiber orientation affect machinability; include the layup spec with your drawing.
At comparable stiffness CFRP is dramatically lighter and does not resonate like metal — valuable for moving robot arms, fixtures and vibration-sensitive structures.
