Joint housings, arm and leg links, sensor brackets and frame plates cut from 6061, 7075 and Ti-6Al-4V. We hold ±0.005 mm on bore fits and wall thickness so the G1 moves the way its kinematics model says it should.
Most of these show up after assembly, not at incoming inspection.
A hip or knee housing machined to ±0.01 mm can shift by 0.02 mm once the hardcoat builds up on the bore. The bearing then sits loose, and the joint develops play within a few hundred cycles. We cut bores undersize on purpose and mask them before coating.
Arm links on the G1 are often 2–3 mm thick to keep mass down. Clamp pressure and tool push-off bend those walls, so the two mounting faces end up non-parallel. Fixture the part from the inside and take light finishing cuts, and the geometry holds.
If the left and right leg brackets are machined on separate setups with different datums, the hole patterns drift apart. Assembly turns into reaming and shimming. Machine both from one datum and one program, and they drop in.
Visible covers and forearm shells are cosmetic parts. Tool marks left at Ra 3.2 μm will still read through a light blast. Step up to a finer finishing pass before blasting if the part is customer-facing.
Five-axis work, tight bore fits and finish control from the same setup.
The G1 carries 23 degrees of freedom in the base model and up to 43 on the EDU variant, with knee torque up to 90 N·m on the G1 and 120 N·m on the EDU. Those loads land on the housings and links. Bore concentricity between the motor mount and the bearing seat matters more than any single dimension on the print.
We machine these on simultaneous 5-axis centers so the bearing bores, motor faces and mounting holes come off one datum. That removes the stack-up you get from flipping the part across three setups. Material is usually 6061-T6 or 7075 for the links, Ti-6Al-4V where wear resistance at the joint matters.
The G1 routes its electrical harness through hollow sections to keep the body clean and serviceable. That puts a lot of small brackets, standoffs and pass-through plates into the build, each with its own hole pattern and clearance requirement.
These parts are small and easy to get wrong by hand. We run them on 3-axis and 4-axis mills with soft jaws or dedicated fixtures, batch by batch, so a 50-piece run matches the first article. Cosmetic covers get a finer finishing pass, then bead blasting or anodizing.
Pick the process by load path and quantity, not by habit.
| Part family | Process | Why |
|---|---|---|
| Hip, knee or shoulder housing | 5-axis milling | Bores and faces off one datum |
| Arm or leg link | 5-axis milling | Thin walls, angled faces |
| Sensor bracket, standoff | 3-axis or 4-axis milling | Small parts, high repeat count |
| Cosmetic forearm cover | 3-axis milling + finishing | Surface finish matters more than load |
| Motor shaft, pivot pin | CNC turning or mill-turn | Round geometry, tight concentricity |
| Frame plate, chassis panel | Sheet metal or milling | Flat parts, quantity dependent |
| Housing shell in volume | Metal die casting + machining | Cost drops above a few thousand units |

Fifteen years of precision work across three wholly-owned plants and 7,600 m² of floor space.
Sixteen 5-axis, twelve 4-axis, twenty-seven 3-axis and sixteen mill-turn centers, so capacity is not the bottleneck.

High cycle counts demand bores that stay round after coating. We machine undersize and mask before anodizing.
Fast joint movement loads thin arm links. Controlled finishing passes keep wall thickness uniform.
Depth camera and LiDAR mounts need repeatable hole patterns across a batch, not one good sample.
Visible covers go through a finer pass, then bead blasting or anodizing, so tool marks do not read through.
Yes, if the critical features are defined. Send what you have: a STEP file, a 2D print, or a scan of the original part.
We will flag anything that cannot be set from the files during the DFM review, which comes back with the quote. Bores, fits and hole patterns need a stated tolerance or we will ask.
6061-T6 is the default for most housings. It machines cleanly, takes anodizing well and keeps mass low.
Move to 7075 if the part sees high bending load and you can accept lower corrosion resistance. Ti-6Al-4V is worth the cost where the joint wears against another surface and you need the extra hardness.
Hardcoat builds roughly 0.025 to 0.05 mm per surface, which will close a bearing fit. We cut the bore undersize by the coating thickness and mask it where the bearing seats.
Tell us the coating spec and target fit at the quoting stage. Retrofitting that decision after machining usually means remaking the part.
There is no minimum order quantity. We will run one part for a fit check and the same program for a 10,000-part production run.
For one-offs the setup cost dominates. If a bracket is still in design, prototyping on a 3-axis mill is usually cheaper than committing to a fixture.
Both are programmed from the same datum and cut on the same machine where the geometry allows. Mirror parts are built as mirror toolpaths, not as a flipped setup.
That keeps hole patterns and bore positions consistent across the pair. Batch inspection data is available if you want it.
Yes. An NDA is available on request, and uploads are handled as secure and confidential.
Robot designs are competitive work. We keep drawings and CAD files tied to your project and do not reuse them across customers.
A STEP or IGES file, a 2D drawing with tolerances and finish callouts, the material, and the quantity.
Without a drawing we can still quote general tolerances, but tight bore fits and surface finish need to be stated. Quote and DFM feedback come back within 12 hours.
Typical turnaround is 3 to 5 days after production starts, and production can begin within 24 hours of a locked drawing and material.
Small brackets and simple plates move fastest. Five-axis housings with multiple tight bores take longer because of setup and inspection time.
