Precision machining of mechanical parts is a type of machining, but it is precision machining. With the development of industry and the continuous changes in demand, tight machining has changed a lot. Its classification is becoming more and more diverse, and its direction is becoming finer and more specialized. With the development of technology, its technology is constantly improving, and the quality and accuracy of machining are also getting higher and higher. The development of technology and economy has led to a close relationship with the direction of mechanical development.

There are many types of mechanical equipment for precision machining of mechanical parts, such as lathes, milling machines, planers, grinders, and broaching centers. The inherent machining accuracy of each equipment is different. Therefore, to achieve precision machining, it is necessary to choose the corresponding process route and equipment based on the high precision of your parts.

The automation level of precision parts processing is very sufficient, greatly reducing the physical labor intensity of workers. Workers do not need to operate the entire process like ordinary lathes, but mainly observe and supervise the lathes. However, the technical content of corresponding CNC machining is higher than that of ordinary lathes, so it requires higher mental labor compared to ordinary lathes.
