Mastering the Challenges of
Copper Fabrication

Copper offers exceptional high electrical conductivity and high thermal conductivity, but its softness and gummy machining behavior make it one of the most difficult materials to process accurately. Tool adhesion, burr formation, and surface tearing can affect part quality if proper machining strategies are not applied.

Our copper CNC machining services utilize specialized diamond-coated tooling, optimized cutting parameters, and high-pressure coolant systems to achieve high precision results for demanding applications.
