What are the material requirements for precision machining of parts

Precision machining is not suitable for all materials. Some materials have a hardness that exceeds the hardness of the machining parts, which may cause the parts to break. Therefore, these materials are not suitable for precision machining unless they are made of special materials or laser cutting. So what are the material requirements for precision machining of parts? Let's take a look together below.

For precision machining materials, they are divided into two categories: metallic materials and non-metallic materials.

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

The processing of ceramics, plastics, and other materials belongs to the processing of non-metallic materials.

1. Firstly, there is a requirement for the hardness of the material. In some cases, the higher the hardness of the material, the better. However, due to the hardness requirements of the machining parts, the material cannot be too hard. If it is harder than the parts, it cannot be machined.

2. Secondly, the material should be moderately soft and hard, at least one level lower than the hardness of the parts. At the same time, it also depends on the purpose of the processed components and the reasonable selection of materials for the parts.

In short, there are still some material requirements for mechanical processing, and 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.

So, before processing, it is necessary to pay attention to the density of the material. If the density is too high, it is equivalent to a high hardness. If the hardness exceeds the hardness of the machine (lathe tool), it cannot be processed. It will not only damage the parts, but also cause danger, such as the tool flying out and injuring people. So, generally speaking, for mechanical processing, the material material should be lower than the hardness of the machine tool in order to be processed.
