The answer is yes. The materials of precision machining parts are divided into two categories: metallic materials and non-metallic materials. For metal materials, the hardness is stainless steel the highest, by cast iron, by copper, and finally aluminum. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials.

Manufacturers of precision machining parts must pay attention to the density of the material before processing. If the density is too high, it is equivalent to a high hardness. If the hardness exceeds the hardness of the lathe tool, it cannot be processed. It will not only damage the parts, but also Cause danger, such as the knife flying out and hurting people.

Not all materials are suitable for processing. Materials that are too soft or too hard are either unnecessary or impossible to process. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machining parts. The processed material cannot be too hard. If it is harder than the machined parts, it cannot be machined. Secondly, the material is moderately soft and hard, which is at least one grade lower than the hardness of the parts. At the same time, it also depends on the function of the processed devices and the reasonable selection of materials for the parts. For machining processing, the material quality must be lower than the hardness of the machine tool, so that it can be processed. Not all materials can be precision machined. Some materials have too much hardness and exceed the hardness of the machined parts, which may break the parts. Therefore, these materials are not suitable for precision machining unless they are made of special materials. parts, or laser cutting.
