CNC machining is a precision subtractive manufacturing process used to produce high-tolerance custom metal and plastic parts. It is commonly divided into 3-axis, 4-axis, and 5-axis machining according to movement flexibility and part complexity. 3-axis CNC is cost-effective for simple flat and standard parts. 4-axis machining adds rotational movement to complete multi-sided machining in one setup. 5-axis CNC enables full-angle machining for complex, curved, and high-precision components. Widely applied in die casting post-processing, these multi-axis CNC solutions ensure accurate dimensions, smooth surface finishes and reliable performance for automotive, electronic, and industrial components.
