How to say, the so-called machinery industry, if only the industry related to mechanical processing, can be said to be the machinery industry, which can be divided into the broad sense machinery industry and the narrow sense machinery industry. At present, the machinery industry in China can be said to be too low. Compared with the West, there are many large workshops, usually processing materials, drawings and other things are foreign, but in the coastal area, Although it is a manual workshop, most of them have their own numerical control equipment, with high processing efficiency, usually mold based, and hardware.
The automatic lathe can automatically finish the multi process processing of small and medium-sized workpieces according to a certain program, automatically load and unload materials, and repeatedly process a batch of the same workpieces, which is applicable to a large number of large-scale production. Special lathe is a kind of lathe used to process the specific surface of a certain kind of workpiece, such as crankshaft lathe, camshaft lathe, wheel lathe, axle lathe, roll lathe and ingot lathe.
(1) The development is uneven, and the overall product level is low. Although the products of some enterprises have reached or are close to the international advanced level, overall, there is still a big gap between the accuracy of the mold, the roughness of the cavity surface, the production cycle, life and other indicators and the overseas advanced level.
(2) The technology and equipment are backward, and the organization and coordination strength are poor. Although some enterprises have changed their skills in recent years, the technology and equipment level is still relatively advanced, and the equipment level of some foreign-funded enterprises is not lagging behind overseas.
