As a leading CNC Machining manufacturer, EMAR specializes in high-precision copper parts CNC machining for industries ranging from electronics to aerospace. Our advanced 5-axis CNC machines and ISO 9001-certified processes ensure exceptional dimensional accuracy and surface finishes for your custom copper components.
Why Choose CNC Machining for Copper Parts?
Copper's excellent electrical/thermal conductivity makes it ideal for heat exchangers, electrical contacts, and RF components. However, its softness and gummy nature require specialized CNC machining techniques. Our solutions include:
- Precision cooling systems to prevent workpiece deformation
- Optimized tool paths to minimize material adhesion
- Micro-machining capabilities (±.005mm tolerance)
- Post-processing options (electroplating, polishing, passivation)
