Part quantities
Built for demanding assemblies
Conductivity, thermal transfer, wear resistance, and dimensional control in one manufacturing workflow.
Material expertise
Copper alloys engineered for robotic performance
Copper and its alloys deliver properties that are difficult to replace in robotics. Their ductility, thermal conductivity, and work-hardening behavior require carefully controlled machining methods and tooling.
Brass machining focus
Reliable threads, connectors, and mounting features
Manufacturing capabilities
Complex copper alloy parts, controlled from setup to inspection
Multi-axis CNC milling and turning centers support the geometry required by modern robotics. Our process is optimized for non-ferrous metals, with controlled cutting parameters, high-pressure coolant, and suitable tool geometry to reduce deformation, burrs, and gummy chip formation.
Designed around your assembly requirements
We review tolerances, access, threads, thermal features, and surface requirements before production begins.
| Capability | Specification |
|---|---|
| CNC Milling | 3, 4, and 5-axis machining for complex housings and brackets |
| CNC Turning | Precision turning with live tooling for shafts and bushings |
| Tolerance | Standard ±0.01 mm; precision down to ±0.005 mm |
| Surface Roughness | Down to Ra 0.4 μm |
| Quantities | 1 to 10,000+ pieces |
| Lead Time | Prototypes in 3–7 days; production in 7–20 days |
Application coverage
Parts that solve real robotics challenges
We machine copper and brass components where electrical performance, heat transfer, wear resistance, and precise assembly all matter.
Electrical & Control
Custom busbars, grounding terminals, electrical connectors, and housing inserts for wiring management.
Thermal Management
Machined copper cold plates, heat sinks, and thermally conductive mounts for motors and controllers.
Motion & Friction
Bearing seats, thrust washers, bushings, and guide components for joints and linear motion systems.
Precision Assembly
Threaded brass inserts, mounting adapters, and sensor housings requiring accurate dimensional control.
Engineering support
DFM guidance before metal is cut
Copper alloys can produce gummy chips and may affect finish or tolerance if not machined correctly. Our engineering team reviews every CAD model and drawing to improve manufacturability, control cost, and reduce assembly risk.
Thermal features
Wall thickness guidance for heat sinks and enclosures.
Tool access
Corner radii recommendations for standard tooling.
Thread control
Thread tolerance review for brass components.
Finish targets
Surface requirements for conductivity and appearance.
Quality and finishing
Inspection and finishing aligned to your drawing
Robotics components are often part of larger, high-value assemblies. Our inspection protocols verify dimensional requirements and critical fits before shipment.
- ●CMM inspection: Complex geometric tolerances and true position.
- ●Optical measurement: Delicate copper and brass features.
- ●Precision gauging: Bore gauges, thread gauges, and micrometers.
- ●Documentation: Inspection reports, material certificates, and traceability records upon request.
Secondary processing
Finish the part for its operating environment
Nickel or tin plating
For busbars and contacts requiring oxidation protection and improved solderability.
Passivation
Cleaning and surface protection for copper alloy components.
Polishing or brushing
Cosmetic improvement or reduced surface friction.
Laser marking
Part identification, serial numbers, and assembly instructions.
