CNC Machined Robot Components

Robot components have to satisfy three masters at once: stiffness, weight and tolerance. Cut one corner and the arm gets slower, the payload drops, or the interface wears. Our robot parts are machined with all three in mind.

Why ProtoTech

Why equipment manufacturers choose us

Weight where it moves

Aluminum, titanium and CFRP reduce moving mass — faster cycles, higher payload, cooler motors.

Interfaces that stay true

Bearing seats and interface features at ±0.005 mm typical where applicable keep joints precise over the machine's life.

Matched sets, not loose parts

Adapter, mount and link supplied together with consistent interface tolerances across the assembly.

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

Arm links and structural bodies, joint and gearbox housings, end-effector parts, adapters and sensor mounts — machined complete to your print.
CFRP is lightest at equal stiffness, titanium next, aluminum the economical workhorse. We machine all three and discuss the trade-off with payload and cost in mind.
Yes — matched sets are routine; interfaces are machined and inspected consistently so the assembly fits the first time.
