We machine the joints, actuator housings, gearbox components and mounting fixtures that go into mobile industrial robots. Tolerances to ±0.005 mm, 16 simultaneous 5-axis centers, one prototype to 10,000+ parts.
These failures show up on the assembly floor, not in the drawing.
A joint bore drilled 0.02 mm oversize lets the harmonic drive slip under load. The arm drifts a few tenths of a degree each cycle. By the end of a shift the repeatability is gone and you're re-teaching waypoints. The fix starts at the boring bar, not in the controller.
If the mounting face on a gearbox housing is out of flat by more than 0.01 mm, the gear mesh loads unevenly. You hear it first as a whine at speed, then as pitting on the tooth flanks. Flatness on the mating face is the variable that decides gear life.
A mobile base sees continuous low-amplitude vibration from drive motors. A mounting plate with soft corners or a loose dowel pin hole loosens over weeks. Bolts back out, the sensor bracket shifts, and your calibration drifts out of spec between service intervals.
A machined prototype that works in the lab often can't be made the same way at volume. Wall thickness changes, tolerances relax, and suddenly the production part doesn't fit like the prototype did. Plan the process once, and both ends match.
We machine the parts around the joint, not the whole robot.
Robotic joints live or die on bore geometry. A harmonic drive needs a bore that is round, straight and sized within a few microns of nominal. We bore these features on 5-axis centers with in-process probing, then verify roundness and diameter before the part leaves the machine.
For gearbox housings and actuator bodies, flatness on the mounting face matters as much as the bore. We face these surfaces in a single setup where possible, so the bore axis and the mounting face stay perpendicular. That keeps gear mesh even across the load range and cuts the noise floor.
We hold ±0.005 mm on critical features as a routine capability, not a best-case number. Surface finish lands between Ra 0.8 and 1.6 μm on bearing bores, and we can go to Ra 0.2–0.8 μm where a seal or a sliding fit needs it.
A mobile robot arm carries a lot of features that point in different directions. Motor mounting pads, cable routing channels, sensor bosses, dowel pin holes. On a 3-axis mill each face becomes another setup, and every setup adds stack-up error. That error lands right where you can least afford it, on the joint.
We run 16 simultaneous 5-axis machining centers. A part with five or six angled faces comes off the table in one or two setups instead of six. Positional relationships between features stay locked to the same datum, so a sensor boss and its mounting holes stay aligned to the joint bore.
The same setup discipline applies to thin-wall actuator housings. Cutting pressure pushes a thin wall, so we adjust step-downs and tool engagement to keep deflection inside tolerance. If a wall is too thin to hold, we'll say so at the DFM stage rather than after the first article.
The right choice depends on where the part sits and what it has to survive.

|---|---|---|
| Joint housings | 7075-T6 aluminium | High strength-to-weight for moving mass |
| Gearbox housings | 6061-T6 or 2024 | Stable, machinable, good fatigue life |
| Mounting plates | 6061-T6 or 5083 | Flat, weldable, corrosion resistant |
| Sensor brackets | 6061 or 304 stainless | Rigid and dimensionally stable |
| Wear pins and dowels | 440C or 17-4PH | Hard, wear resistant, holds fit |
| Insulating spacers | PEEK or POM | Non-conductive, low creep |
| Covers and guards | ABS, PC or PMMA | Light, tough, easy to form |
| Base frames | 4130 or 4140 steel | Stiff under continuous vibration |
One shop for the machined parts, the fixtures and the finishing.
Angled faces, compound bores and contoured surfaces cut in one or two setups. The right call for joint housings and anything with features on multiple planes.
Efficient for prismatic parts, plates and brackets where the features sit on one or two faces. Lower cost per part at volume.
Shafts, pins, bushings and rotary actuator bodies. 16 mill-turn centers handle turned features and cross-drilling in one cycle.
One-off and low-volume parts for design validation. Quotation and free DFM analysis within 12 hours, production can start within 24 hours.
Anodizing, electroless nickel, black oxide, bead blasting and polishing. Laser marking down to 1.5 mm character height.
Build fixtures, weld fixtures and assembly jigs. Machined to the same tolerances as the parts they hold.
Numbers you can check against your part envelope.

No. We machine components that go into robotic systems, including joint housings, actuator bodies, gearbox parts, mounting fixtures and custom tooling.
If your part is a machined metal or plastic component, we can quote it. We do not assemble or sell finished robot systems.
We hold ±0.005 mm on critical features as a routine capability. That covers bore diameter on most harmonic and cycloidal drive seats.
If your design calls for something tighter, send the drawing and we will tell you whether it is machinable and how we would inspect it. We would rather flag it at the DFM stage than discover it after the first article.
Count the faces that carry critical features. If everything sits on one face, 3-axis is cheapest. Two or three faces favor 4-axis. If features point in five or six directions, 5-axis wins because it avoids the extra setups and the stack-up error that comes with them.
For a joint housing with angled motor pads, 5-axis is almost always the right call. For a flat mounting plate, it is not worth the machine time.

Yes. There is no minimum order quantity, so we can machine one prototype and then scale the same process to 10,000+ parts.
The benefit is that the production part uses the same datums and fixturing as the prototype. Tolerances do not relax between the two runs, so what fit in the lab fits on the line.
Anodizing in clear, colour, hardcoat and conductive versions. Electroless nickel, zinc, silver and gold plating. Powder coating and black oxide. Bead blasting, tumbling, brushing and polishing.
