Drawing-based manufacturing – Custom copper parts made according to customer drawings and 3D files.
Copper machining experience – Process review for burrs, deformation, tool marks and surface finish requirements.
Flexible production – Prototypes, small batches and repeat production supported.
Inspection support – Key dimensions, threads, holes and surface quality checked before shipment.
Documents available – Inspection reports and material certificates can be provided when required.
Copper has excellent electrical and thermal conductivity, but it can be challenging to machine because it is soft, ductile and prone to burrs or tool marks. Chip control, sharp tooling, suitable cutting parameters and coolant are important for stable machining quality.
Xintao reviews copper part drawings before production and selects suitable machining methods according to material grade, tolerance, surface finish and part structure.
C110 copper is commonly used for conductive CNC machined parts due to its high electrical conductivity and availability. For improved machinability, C145 tellurium copper may be considered. For high-strength conductive parts, C172 beryllium copper may be suitable, depending on project requirements.
