Products Description
Copper in CNC Machining refers to a manufacturing process that utilizes high-purity T2 copper as raw material, employing computer numerical control (CNC) machine tools to perform precision operations such as turning, milling, and drilling. This process is specifically dedicated to the production of custom metal components characterized by complex geometries, stringent dimensional tolerances, and exacting requirements for electrical and thermal conductivity. Widely applied across sectors such as power transmission, semiconductor manufacturing, high-frequency communications, and advanced thermal management, it serves as a pivotal manufacturing method for realizing designs driven by specific functional and performance objectives.
Material Composition
Core Material
T2 Oxygen-Free Copper. With a copper content of ≥99.95% and extremely low oxygen levels, it boasts superior electrical and thermal conductivity, as well as excellent ductility and corrosion resistance, making it the preferred material for the Copper Rolling Mill. For specialized applications, C10100 (Oxygen-Free Copper) or C11000 (Electrolytic Tough Pitch Copper) may be utilized.
Material Forms
Rods, plates, blocks, and tubes. The specific form is selected based on the shape and dimensions of the End Mill for Copper to maximize material utilization efficiency.
Material Temper
Typically supplied in a soft (annealed) temper to facilitate complex shaping and cutting operations. For Mill Finish Copper requiring higher hardness, cold working or heat treatment processes may be applied following machining.

Working Principle
Material Removal
High-speed rotating cutting tools are utilized to machine the Copper Rolling Mill. Due to the high ductility of red copper, the cutting process primarily induces plastic deformation rather than brittle fracture; consequently, specific requirements are placed on the sharpness of the cutting tools and the design of the chip evacuation flutes.
Precision Control
CAM software is employed to simulate tool paths and precisely control feed rates and spindle speeds. This prevents thermal expansion and deformation of the red copper caused by cutting heat, thereby ensuring dimensional stability for End Mill for Copper.
Stress Relief
A stress-relieving operation is introduced between the roughing and finishing stages to prevent the release of internal residual stresses within the red copper, which could otherwise lead to Mill Finish Copper warping.
