5-axis CNC machining is the core technology for processing complex precision mold parts. Unlike traditional 3-axis machining, 5-axis CNC machining can rotate the workpiece around two additional axes, enabling the processing of complex curved surfaces and irregular shapes with high precision for precision mold parts machining. We use imported 5-axis CNC machining centers with a positioning accuracy of ±0.001mm, which can processprecision mold components with complex structures (such as mold cores, cavities, and sliders) in one setup, reducing precision mold processing errors and improving efficiency. This technology is widely used in automotive, aerospace, and electronics industries for high-precision mold parts machining.
