We machine gears, sensor housings, mounting brackets, and wheel hubs for AMRs, AGVs, and pick-and-place arms. Tolerances hold at ±0.005 mm, every part is inspected, and runs go from one prototype to 10,000+ pieces.
These are the failures we see before a part ever reaches Phoenix.
A gearbox housing bore that drifts 0.02 mm off center shows up as repeatability error at the gripper. The arm misses a tote by 5 mm, the pick fails, and the cell drops to manual recovery. That cost lands on the integrator, not the machinist who cut it.
A sensor or motor housing machined from the wrong alloy traps heat instead of spreading it. Electronics drift, LiDAR returns get noisy, and the AMR starts hesitating in aisles. By the time the fault is traced back to a bracket, the install schedule has already slipped.
Mounting brackets see millions of load cycles over a warehouse shift. A sharp internal corner or a rough surface finish becomes a crack start. The part passes first article, then fails six months in, and the replacement sits on a slow boat from overseas.
You send drawings out and wait a week for pricing. Then the supplier asks about material, then about finish, then about quantity. Every round trip pushes the prototype back a day. For a Phoenix integrator with a fixed install date, that is the real bottleneck.
One shop for the whole component set, from gear to enclosure.
AMR chassis plates, arm links, and joint housings carry features on five or six faces. Each refixture adds stack-up error. On our 16 simultaneous five-axis centers, we cut those faces in a single setup, so the bore-to-bore relationship stays where the drawing puts it. A 750 × 1,150 × 550 mm work envelope covers most robot link and base plate sizes; the large-format machines reach 4,000 × 400 × 150 mm for long rails and gantry beams.
Positional accuracy is only half the job. The other half is stiffness under cutting load, which is why we keep separate roughing and finishing passes on aluminum and stainless. Thin-wall housings get light radial cuts and a support fixture so the wall does not deflect and spring back. When a part cannot be held rigidly, we say so before quoting, because a warped housing that measures fine on the bench will not measure fine bolted to a robot.
Wheel hubs, drive axles, lead-screw nuts, and encoder shafts are round parts, and round parts live or die on concentricity. Our 16 mill-turn centers cut the bore, the outer diameter, and any cross-drilled holes without releasing the part from the spindle. Wheel hub concentricity within 0.005 mm keeps an AGV tracking straight instead of crabbing down the aisle. The Ø400 mm rotary table handles larger flanges and turntable rings.
We check roundness and runout on the machine before the part comes off, then again on the CMM. If a shaft needs a press fit into a bearing, we hold the tolerance band tight rather than sitting at nominal and hoping. That is a boring answer, and it is the one that keeps a drive unit from whining at 1.5 m/s.
Match the part family to the process before you request a quote.
| Part family | Recommended process | Why it fits |
|---|---|---|
| Joint housing, arm link | 5-axis machining | Multi-face features in one setup |
| Wheel hub, drive axle | Mill-turn | Concentricity held without re-chucking |
| Chassis plate, base frame | 3-axis or sheet metal | Flat geometry, cost per part matters |
| Sensor enclosure | 3-axis + anodizing | Simple cavity, thermal path on OD |
| Gear blank | Turning + hobbing prep | Round stock, tight bore tolerance |
| Prototype bracket | 3-axis, one-off | Fastest route to a fit check |

Six points, each one backed by a number you can check.
Fifteen years cutting metal, three wholly-owned plants, 150 technicians across Dongguan and Singapore. Robot parts are not a side line here.
Critical bores and bearing fits held at ±0.005 mm. We inspect 100% of parts before shipment and send reports on request.
16 five-axis, 12 four-axis, 27 three-axis, and 16 mill-turn centers. Capacity to absorb a production ramp without re-queueing.
Quotation and free DFM analysis within 12 hours. Production can start within 24 hours of drawing release.
ISO 9001:2015, IATF 16949:2016, ISO 13485:2016, ISO 27001:2022. Documented process control, not a poster on the wall.
Historical late-delivery probability below 2%. Uploads stay confidential, and an NDA is available on request.
Flat plates carrying battery, drive, and sensor mass. Flatness and hole position drive assembly time.
Multi-face geometry with bore-to-bore relationships. Cut in one setup to cut datum stack-up.
Housings that must spread heat and shield electronics. Wall thickness and thermal path matter.
Round parts where runout shows up as aisle drift. Turned and checked before the part comes off.
It is automation deployed inside a warehouse or stockroom: autonomous mobile robots moving totes, automated guided vehicles following fixed paths, and robotic arms doing pick-and-place. The parts we machine sit in those systems as joint housings, wheel hubs, chassis plates, sensor enclosures, and mounting brackets.
The common thread is duty cycle. These machines run through shifts, so components see constant load reversals and small alignment errors compound over millions of cycles.
Aluminum 6061-T6 for chassis plates, brackets, and enclosures where weight and thermal conductivity both matter. 7075 for loaded links that need higher strength. 304 or 316L stainless for shafts and any part near washdown or moisture.
For wear surfaces, 17-4PH stainless or 4140 steel after heat treatment. For low-friction guides and bushings, POM or PEEK. We will flag it if a material choice is fighting the geometry.
Cut the mating faces in one five-axis setup so the bores share a single datum. Every refixture adds error, and on a joint housing that error shows up directly as backlash at the gripper.
We verify bore-to-bore position on the CMM after machining and compare against the drawing before the part moves to finishing.
Yes. There is no minimum order quantity, so a single prototype and a 10,000-part run are both fine. Most prototype brackets run on three-axis machines with a fast setup.
Quote and free DFM analysis come back within 12 hours, and production can start within 24 hours after the drawing is released.
Anodizing in clear, color, hardcoat, and conductive variants; electroless nickel, zinc, silver, and gold plating; powder coating and black oxide; bead blasting, tumbling, brushing, and polishing.
Laser marking and engraving are available with a minimum character height of 1.5 mm. Tell us if the part is a wear surface, because that narrows the finish list quickly.
Light radial cuts, a support fixture, and roughing separated from finishing. Thin aluminum walls deflect under tool pressure and spring back after the cut.
If a wall is too thin to hold at ±0.005 mm, we say so at quote time and propose a change rather than shipping a part that only measures correctly off the fixture.
Every part is inspected before shipment. That covers raw material check, in-process monitoring, and final inspection. Reports are available on request.
We work to ISO 9001:2015, IATF 16949:2016, ISO 13485:2016, and ISO 27001:2022 process controls. Uploads are secure and confidential, and an NDA is available.
Quotation and DFM feedback land within 12 hours. Production can start within 24 hours, and parts typically ship in 3–5 days.
Historical late-delivery probability is below 2%. We quote the schedule we can actually hit, and we tell you early if a feature needs a second operation.
