What are the material requirements for precision parts processing?

For precision parts processing, not all materials can be precisely processed. Some materials are too hard, exceeding the hardness of the processed parts, and the parts may collapse. Therefore, these materials are not suitable for precision machining, unless they are Machine parts made of special materials, or laser cutting.

For precision machining materials, they are 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 for precision machining

1. According to the introduction of precision parts processing manufacturers, the first is the requirements for material hardness. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the processed parts. The processed material should not be too hard, if it is better than the machine part. It just can’t be processed.

2. Secondly, the material is moderately hard and soft, at least one grade lower than the hardness of the machine. At the same time, it also depends on the purpose of the machined device and the rational selection of the machine.

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, according to the analysis of precision parts processing companies, the most basic one is that you must pay attention to the density of the material before processing. If the density is too large, the hardness is also large, and if the hardness exceeds the hardness of the machine (lathe tool), It just can’t be processed. It will not only damage the parts, but also cause dangers, such as the turning tool flying out and hurting people. Therefore, in general, for mechanical processing, the material material must be lower than the hardness of the machine knife, so that it can be processed.
