CNC Machining for Robotics Manufacturers and System Integrators
When you build robots, the mechanical parts are not commodities — they are what make the machine move, hold position and survive the environment. ProtoTech works with robotics manufacturers, robotic system integrators and autonomous systems developers who design their own equipment and need a machining partner that understands tight tolerances, complex geometries and recurring supply.
We machine the parts inside your robot: robotic arm components, housings, structural frames, motion parts and custom mechanical assemblies — in aluminium, stainless steel, titanium and engineering plastics such as PEEK, PVDF and PTFE.

Robotic Components We Machine
We work from the perspective of the parts inside your equipment — not from a machine-count brochure.
| Component | Description |
|---|---|
| Robotic Arm Components | Joints, links, arm segments — precision shafts and motion parts |
| Robot Housings | Gearbox housings, drive cavities, sensor enclosures |
| Robot Structural Components | Bases, frames, mounting plates |
| Fixtures & Brackets | Assembly fixtures, mounting brackets |
| Connectors & Flanges | Interface parts, flanges |
| Mechanical Assemblies | Multi-part mechanical assemblies |

Materials for Robotics — Metals and Engineering Plastics
Robotics demands both lightweight structures and wear-resistant, chemical-resistant or electrically stable parts. ProtoTech machines:
- Aluminium & Stainless Steel — structural parts and housings
- Titanium — high strength-to-weight arms and subsea parts
- Engineering Plastics — PEEK, PVDF, PTFE, POM for low-friction, insulating or chemically stable components

Capabilities for Complex Robotics Parts
- 5-Axis Machining — complex monolithic arms and housings in one setup → 5-Axis Machining
- Precision CNC Turning — shafts, pins, threaded parts → CNC Turning
- Swiss Machining — small-diameter precision parts → Swiss Machining
- Tight Tolerance Machining — repeatable ±0.005 mm class → Tight Tolerance
Quality, Inspection and Traceability
For robotics manufacturers, a failed component means a failed machine in the field. ProtoTech provides dimensional inspection, inspection reports, material certification and full traceability — so your quality team can qualify us for recurring production with confidence.
Our in-house metrology includes a Zeiss coordinate measuring machine (CMM) for full dimensional inspection and First Article Inspection (FAI), plus a benchtop material spectrometer to verify incoming stock against the specified grade. Every shipment can be supplied with EN 10204 3.1 material certificates and lot-level traceability, backed by ISO 9001:2015 (AENOR).
From Prototype to Recurring Production
We support the full lifecycle of your robotics program:
- Prototype — first articles and design validation
- Pre-Series — small batches before ramp-up
- Recurring Production — scheduled supply of multiple part numbers
- Series Production — volume supply with stable lead times
