Automotive Manufacturing Services

CNC turning is widely used in the manufacturing of automotive parts, mainly for processing rotationally symmetrical parts, such as shafts, wheels, engine parts, etc. CNC lathes can achieve high-precision processing of circular, cylindrical or complex contours.
CNC milling is a common way to cut and process automotive parts through computer numerical control technology, which can perform complex cutting and engraving in three-dimensional space. CNC milling is widely used in automobile manufacturing, especially for parts with complex geometries and high precision.
CNC drilling is a technology that uses computer numerical control (CNC) machine tools to perform precision drilling on automotive parts. It can efficiently and accurately process a variety of materials, including metals, plastics, and composite materials. The automotive industry has very strict requirements for the drilling of parts, so CNC drilling is widely used in the manufacturing process of body structures, engine components, chassis components, etc.
