We Are Your Reliable Supplier on Robotics Parts

CNC precision machined components for embodied humanoid robot: joint structural parts, connecting supports, precision shafts, end cap flanges, cavity bases, reducer mounting seats, actuator housings and other robot core mechanical parts.

Material, Function & Technical Specifications

Materials

- Aluminum Alloy 6061 /7075: joint housing, support bracket, flange, base. Light weight & high strength, anodized for wear and corrosion resistance.

- Oxygen-free Copper: thermal & electrical conductive components. High thermal & electrical conductivity, low oxygen content for robot thermal management system.

- Stainless Steel SUS304 / SUS316 / 420: precision mandrels & locating pins. Excellent wear resistance and dimensional stability.

Function

Provide structural support, positioning installation, load bearing, transmission matching, heat dissipation and electrical connection for multi-DOF joints, perception modules and actuators of humanoid robots. Ensure motion accuracy, structural rigidity and long-term operation stability.

Technical Parameters

  • Dimensional Tolerance: ±0.005~±0.02 mm for critical fitting dimensions; ±0.03~0.05 mm for general structural dimensions.
  • Geometric Tolerance: Coaxiality ≤0.003 mm, parallelism & perpendicularity ≤0.005 mm, circular runout ≤0.004 mm.
  • Surface Roughness: Ra 0.4~0.8 μm for mating surfaces; Ra1.6~3.2 μm for non-mating cosmetic surfaces.
  • Surface Treatment: Hard anodizing / natural anodizing for aluminum; passivation for stainless steel; polishing & anti-oxidation treatment for oxygen-free copper.
  • Performance: Lightweight, resistant to alternating load, low stress deformation, no internal porosity, suitable for continuous reciprocating motion.

Why Customers Choose Us & Technical Problems We Solve

High-precision complex cavity machining: Humanoid robot parts feature irregular shapes, multi-hole layout and thin-wall structures which are prone to deformation. Our mature clamping & process control effectively reduce thin-wall distortion and guarantee geometric tolerance to meet high-precision assembly requirements of robot joints.

One-stop multi-material supply: We manufacture aluminum, stainless steel and oxygen-free copper parts in one factory. Customers do not need to coordinate multiple vendors, lowering communication cost and inconsistent quality risk.

Strict surface quality control: Oxygen-free copper easily oxidizes and aluminum tends to have tool marks. Our polishing, deburring and anti-oxidation process stabilize surface finish for heat conduction & electrical application.

Fast prototype & mass production: Robot R&D requires frequent design iteration. We support rapid prototyping and smooth transition to mass production, shortening customer development cycle.

Traceable quality system: Certified with ISO9001, IATF16949. Inspection reports available for every batch to meet high reliability requirements of robot industry.
