About Yueyi Precision

Precision CNC Machining Services for High-Performance Components

Copper and its alloys—renowned for superior electrical and thermal conductivity—present a unique machining challenge. Their soft, ductile nature leads to issues like built-up edge, poor surface finish, and rapid tool wear. At Yueyi precision, we specialize in precision copper CNC machining, transforming these challenging materials into flawless, high-tolerance components for critical applications in electronics, automotive, and thermal management.

Custom Copper CNC Machining Services

Yueyi Precision specializes in custom copper CNC machining services tailored to meet unique project requirements. Unlike standard off-the-shelf components, our process is optimized for parts that demand exceptional electrical conductivity, tight tolerances, and high-quality finishes. Our precision copper CNC milling capabilities are designed to handle these high-performance needs.

Material & Process Expertise

In-depth knowledge of pure copper (C110, C101), free-cutting alloys (C145), and high-strength beryllium copper (C172), with optimized processes to address copper’s machining challenges—such as built-up edge and rapid tool wear.

Advanced Technical Capabilities

High-speed machining centers, specialized diamond-coated tooling, and high-pressure cooling systems dedicated to non-ferrous copper materials, ensuring clean cuts and consistent surface finishes.

Guaranteed Precision

We consistently hold tight tolerances, typically ±0.005mm, with ±0.003mm achievable for critical features. All parts undergo CMM inspection to verify dimensional accuracy.

Full-Service Solution

From DFM analysis and prototyping to high-volume production, finishing, and certification (ISO 13485, ISO 16949), we support the entire product lifecycle for copper components.

Copper CNC Machining FAQ

Q: What are the biggest challenges in machining pure copper, and how do you address them?

A: The main challenges are its gumminess (causing built-up edge) and high thermal conductivity. We address them with sharp, polished tools with specialized coatings (like diamond), high-pressure coolant to manage heat and clear chips, and optimized high-speed parameters to create a clean shear cut.

A: Yes. We have strict safety protocols for beryllium copper machining. Operations are conducted with appropriate dust collection and filtration systems, and we adhere to all safety guidelines to protect our technicians and environment.

A: For internal components, chemical passivation or clear lacquer works well. For external or conductive surfaces, electroplating with tin, nickel, or silver provides excellent and durable protection against oxidation.

A: We offer quick-turn copper machining services for prototypes, with standard lead times of 5-10 business days. Expedited 3-5 day service is available for urgent needs.

A: Absolutely. Full material traceability and inspection reports (including CMM data if applicable) are standard deliverables, ensuring you have complete documentation for quality control and regulatory compliance.
