How to say, the so-called mechanical occupation, as long as it is related to mechanical processing, can be said to be a mechanical occupation. This is divided into a broad mechanical occupation and a narrow mechanical occupation. Now, my country's mechanical occupation can be said to be too backward. Compared with the West, most of them are craft workshops, which are generally processed with supplied materials, and the drawings are foreign. However, in the coastal areas, although they are craft workshops, most of them have their own numerical control equipment, and the processing power is relatively high. Generally, it is mainly based on molds, as well as hardware.

The automatic lathe can automatically complete the multi-process processing of small and medium-sized workpieces according to a certain program, and can automatically load and unload, and repeatedly process a batch of the same workpieces, which is suitable for mass production. Specialized lathes are lathes used to process the specific appearance of a certain type of workpiece, such as crankshaft lathes, camshaft lathes, wheel lathes, axle lathes, roll lathes, and ingot lathes.

 (1) Unbalanced development and low overall product level Although the products of a single enterprise have reached or approached the international advanced level, on the whole, the mold accuracy, cavity surface roughness, production cycle, life and other indicators are in line with foreign advanced There is still a big gap between the standards.

 (2) The technological equipment is backward and the organization and coordination ability is poor. Although some enterprises have undergone technological transformation in recent years, the technological equipment level is now relatively advanced, and the equipment level of some foreign-funded enterprises is not behind foreign countries.
