CNC milling-turning composite process combines milling and turning operations using Computer Numerical Control (CNC) machines. This process allows for the production of complex parts with both rotational and linear movements. It enhances efficiency by reducing setup times and increasing machining accuracy. CNC milling-turning offers versatility in producing a wide range of components, from prototypes to production runs. This advanced manufacturing technique is widely used in industries such as aerospace, automotive, and medical devices for its precision and productivity.
