Robotics CNC Machining Services

Arm segments and links, joint and actuator housings, gearbox housings, motor mounts, shaft couplings, controller enclosures, sensor mounts, and end effector bodies. We work across industrial, collaborative and mobile robotic platforms.

Robotic arms pay for every gram twice, because mass at the end of a link increases the torque the joint must carry. We start from the load case rather than the drawing: rib layout, wall thickness and pocket depth are set from the bending and torsional loads the link actually sees, then confirmed with precision milling that keeps the mounting interfaces flat and parallel.

Standard machined tolerance is ±0.025 mm, with critical features such as bearing bores and mating faces held to ±0.01 mm where the drawing requires it. Mounting interfaces and rotational features are checked for flatness, parallelism and concentricity, since those are what determine whether an assembly runs true.

Yes. For multi-part assemblies we analyse the stack across the whole chain rather than optimising individual parts, so tolerance is spent where it actually matters. This usually reveals that one or two tight features carry the assembly and the rest can be relaxed, which reduces both cost and inspection time.

Structural metals: aluminium 6061-T6 and 7075-T6 for weight-critical links, steel 4140 and 1045 for loaded shafts and wear surfaces, titanium Grade 5 where strength per unit mass matters most, and brass or bronze for bushings and bearings.

Polymers: POM (Delrin) and nylon for low-friction and wear parts, PEEK for high-temperature components, UHMW-PE for slider pads, and carbon fibre composites where minimum mass governs the design.

Yes. Functional prototypes run on a 2–5 day cycle for design validation, motion testing and integration checks. The same process definition then carries into serial production from 500 up to 100,000+ units, with full batch records so a change in volume does not mean a change in the part.

Yes. We sign unilateral or mutual NDAs before drawing review, restrict drawing access to project engineering personnel, and do not use customer parts for marketing or sample display. Robot kinematics and end effector geometry are usually the core IP, and we treat those files accordingly.
