As a result, the processed parts can not meet the use requirements of mechanical equipment, because in this way, when processing, it is necessary to know the relevant conditions of material requirements clearly!!

If it is to process metal materials, it depends on its hardness. Among many metal materials, stainless steel is the hardest, while cast iron is slightly inferior. The hardness of copper is lower than cast iron, and the hardness of aluminum is the lowest. Therefore, stainless steel should be selected for high hardness requirements of workpieces, while aluminum should be selected for low requirements.

Precision machining

1. First of all, we need to understand the hardness requirements. In some places, the higher the hardness requirements of the equipment on the parts, the better. However, this kind of hardness requirements are generally only for the processing of workpieces. If the material is processed, the hardness cannot be too hard, otherwise it may cause the material to be too hard and affect the normal operation of the machine.

2. Then, it depends on the specific function of the processed parts. If it is used in some high-temperature resistant industries, then the selected materials must be high-temperature resistant materials, and if it is used in some other industries, then select the appropriate materials according to the industry requirements.

The above is the relevant content of the material requirements for precision machining. In short, it has other requirements for the material besides the hardness requirements. The specific requirements must be determined in combination with the situation, or the workpiece produced may not be used because it fails to meet the requirements.
