Machining plays a crucial role in the automotive sector. It involves the manufacturing of automotive parts, including the precision machining of key components such as engines, transmissions, suspension systems, and braking systems. Through turning, milling, drilling, grinding and other processes, the dimensional accuracy and surface finish of parts can be ensured to meet the high performance requirements of automobiles. In addition, machining is also used in the manufacture of automotive molds, which are used to produce various parts of the car body. With the development of technology, the application of CNC machine tools and automated production lines has greatly improved production efficiency and product quality, while also reducing costs. The advancement of machining technology has provided strong support for automotive lightweight, energy saving and environmental protection.
