Precision mechanical parts processing, not all materials can be precision machining, some materials hardness is too large, across the hardness of the processing parts, it may collapse the parts, so these materials are not suitable for precision machining.

Precision mechanical parts processing, not all materials can be precision processing, some materials hardness is too large, across the hardness of the processing parts, it may collapse the parts, so these materials are not suitable for precision machining, unless it is made of special materials, or laser cutting. So what are the requirements for materials in precision parts processing? Let's learn about it together.

About precision mechanical parts processing materials are divided into two categories, metal materials and non-metallic materials.

For metal materials, the hardness is stainless steel, followed by cast iron, followed by copper, and finally aluminum.

The processing of ceramics, plastics, etc. is attributed to the processing of non-metallic materials.

1. First of all, the hardness of the material is required. For some occasions, the higher the hardness of the material, the better. It is only limited to the hardness requirements of the processed parts. The processed material cannot be too hard, assuming that it is harder than the parts.

2. Secondly, the hardness of the material is moderate, at least one level lower than the hardness of the parts. Together, it depends on what the processed parts are used for and reasonable material selection for the parts.

In short, there are still some requirements for precision machining of materials, and not all materials are suitable for processing, such as too soft or too hard materials, the former is not necessary for processing, and the latter is not possible to process.

Therefore, we must pay attention to the density of the material before processing. Assuming that the density is too large, it is equivalent to the hardness. If the hardness crosses the hardness of the machine part (lathe tool), it cannot be processed. It will not only damage the parts, but also pose a danger, such as the tool flying out and hurting people. Therefore, in general, for mechanical processing, the material is lower than the hardness of the machine knife, so that it can be processed.
