Humanoid robot parts supplier with 220 CNC machines, in-house CMM inspection and ISO 9001. Finger joints, sensor housings and brackets, prototype to volume. CHX Metal runs 220 CNC machines in Shenzhen, including Swiss-type lathes and 5-axis machining centres.
Why Buyers Choose CHX Metal as a Humanoid Robot Parts Supplier
Robot programmes move through a prototype stage, a pilot batch and a production ramp, and the supplier has to stay the same across all three. Our plant runs 220 CNC machines - 100 five-axis machining centres, 50 CNC lathes and 70 swiss-type lathes - so a design that is proven on one machine can be scaled on the same process rather than re-qualified at a new vendor.
- One supplier from prototype to series — the same equipment and inspection plan cover a single-piece sample and a monthly production order.
- In-house inspection — 8 inspection instruments including a coordinate measuring machine, with dimensional reports issued on request.
- Material coverage — 7075-T6 and 6061-T6 aluminium, TC4 titanium, 304/316L stainless steel, PEEK, POM and engineering plastics.
- Finishing under one roof — anodising, bead blasting, passivation, polishing and laser marking coordinated with machining.
- Export-ready logistics — protective packaging for high-value assemblies and worldwide shipping by air or sea.
Supply Scenarios We Support
New product introduction (NPI)
DFM feedback on your drawing before tooling, then a first-article sample for design validation.
Pilot and bridge batches
Small lots for field trials and pilot builds, machined without dedicated tooling.
Production ramp
Repeat orders held to the same datum scheme, inspection plan and surface treatment as the approved sample.
Engineering change management
Revised revisions machined and documented so your bill of materials stays traceable.
Spare parts and service kits
Low-volume replacement parts for installed robots and service organisations.
Materials, Tolerances & Documentation
Typical humanoid robot parts are machined to ±0.005 mm on functional features and ±0.005 mm general, depending on the drawing:
- Aluminium 7075-T6 / 6061-T6 — structural links, housings and brackets with a high stiffness-to-mass ratio.
- Titanium TC4 (Grade 5) — highly loaded joints that must resist repeated impact.
- Stainless steel 304 / 316L — wear surfaces, shafts and washdown environments.
- PEEK, POM and PI (polyimide) — insulating carriers and low-friction contact pads.
Documentation: dimensional inspection report, material certificate on request, and packaging sized for robotic assemblies. Confidentiality: drawings and models are handled under NDA and are not shared outside the project team.
Frequently Asked Questions
What is your minimum order quantity? One piece for prototypes, and we accept small pilot lots. Prototype and series parts are machined on the same equipment, so there is no process change between the two.
What lead times can you hold? Typically 5 to 15 working days after drawing approval for machining, plus time for surface treatment. Repeat orders usually run faster once the process is fixed.
Can you supply inspection documentation? Yes. We issue dimensional inspection reports on request and can inspect to your own control plan. Material certificates are available for the metals we machine.
Will you sign an NDA before receiving drawings? Yes. We review and sign confidentiality agreements before any drawing or 3D model is transferred, and files stay inside the project team.
How do you package and ship robot parts? Parts are protected individually, cushioned in foam-lined cartons, and shipped by express air or sea freight depending on volume and destination.
