For Dalian automatic machining, the position of heat treatment process is arranged as follows: in order to improve the cutting performance of metal, such as annealing, normalizing, quenching and tempering, it is generally arranged before machining. In order to eliminate internal stress, such as aging treatment, quenching and tempering treatment, it is generally arranged after rough machining and before finishing machining.

Precision machining乐发vll500 is also called precision machining. It is different from ordinary machining and requires higher precision than ordinary machining. It mainly uses machining machinery to change the overall dimension of the workpiece. According to the temperature state of the workpiece to be processed, it can be divided into two types: cold processing and hot processing.

It is called cold working when it is processed at room temperature but does not cause chemical and physical changes to the workpiece. In the process of production and processing in the machinery industry, although some details are very inconspicuous, if we can get enlightenment from them, draw inferences from one instance, use our brains and find ways, it will still be of great help to our work.

The automation processing industry has developed in recent 10 to several years. Not only the world-famous automation equipment enterprises have settled in China, but also a number of manufacturers with independent intellectual property rights have emerged in China in recent years, such as Xinsong robot and William automation equipment, all of which occupy a place in the automation industry.

乐发vll500From the perspective of China's current manufacturing industry, a large number of workers are still used as labor force. They work on the assembly line all morning and all afternoon. Frankly, such labor intensity is rare in foreign countries. Developed countries set their manufacturing plants in some developing countries or some underdeveloped countries, Let cheap labor help make all kinds of products.
