Dalian automatic processing is widely used in civil and military fields such as national defense, medical equipment, aerospace and electronic production. With the continuous development of the optimization and upgrading of China's industrial structure, the demand for mechanical parts processing is also increasing. Machining refers to the process of changing the overall dimension or performance of the workpiece through a kind of mechanical equipment.

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. That's the processing oil.

Before that, there were diesel and cutting oil in machining. Later, the experiment found that cutting oil is much better than diesel. Cutting oil contains extreme pressure anti-wear agent, antirust agent and other additives. According to different uses, some will add very good anti-wear agent, but diesel does not have these. Therefore, choosing cutting oil in machining is the best choice at present.

It is generally arranged after machining. Precision machining哈希私彩, not all materials can be precision machined. If the hardness of some materials is too high and exceeds the hardness of the machined parts, the parts may collapse. Therefore, these materials are not suitable for precision machining, except for parts made of special materials or laser cutting.
