Although the selection of materials for hardware parts processing is not very strict, it should not be sloppy. Good materials can not only ensure that the equipment will not be damaged too much, but also improve the yield and accuracy of parts. If the purchased materials are not good, such as too high hardness, which exceeds the hardness of the workpiece, the mechanical equipment may be damaged and the workpiece will be affected. Therefore, these materials are not suitable for precision machining. What are the requirements for the use of materials in the processing of hardware parts?

1. The first is the requirements for material hardness. For some occasions, the higher the hardness of materials, the better. However, it is only limited to the hardness of machine tool parts. The processed materials cannot be too hard. If they are harder than machine tool parts, they cannot be processed.

2. Secondly, the hardness of the material is moderate, at least one level lower than the hardness of the machine. It also depends on what the role of the processing device is to do, and the material of the machine should be selected reasonably.

In a word, the processing of precision machined hardware parts has certain requirements on materials, not what materials are suitable for processing,
