Analysis on the requirements of materials for precision mold

Before machining precision parts, you must pay attention to the density of the material. If the density is too large, the hardness is also great. If the hardness exceeds the hardness of the lathe tool, it will not be processed, not only will damage the parts, but also cause danger. , Such as the turning knife flying out to hurt people. So, what are the material requirements for precision mechanical parts processing?

What are the requirements for materials for precision parts processing

For precision processing materials, it is divided into two categories, metallic materials and non-metallic materials. For metal materials, stainless steel has the highest hardness, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials.

Stainless steel materials used in the processing of precision mechanical parts

1. The first is the requirement of material hardness. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machined parts. The machined material should not be too hard. If it is harder than the machine part, it cannot be processed.

2. Secondly, the material is moderate in hardness and hardness, at least one grade lower than the hardness of the machine part. At the same time, it also depends on the purpose of the processed device and the rational selection of the machine part.

In short, precision machining still has some requirements for materials. Not all materials are suitable for processing, such as materials that are too soft or too hard. The former is not necessary for processing, while the latter cannot be processed.

Therefore, generally speaking, for mechanical processing, the material material must be lower than the hardness of the machine knife, so that it can be processed. Not all materials can be precision processed. Some materials are too hard to exceed the hardness of the processed parts, and the parts may collapse. Therefore, these materials are not suitable for precision machining unless they are made of special materials. The machine parts, or laser cutting.
