Material requirements of precision machining manufacturers

Precision machining, not all materials can be precision machining, some materials are too hard, exceeding the hardness of the machine parts, the machine parts may collapse, so these materials are not suitable for precision machining, unless they are special Parts made of materials, or laser cutting.

For precision machining manufacturers, the materials are divided into two categories, metallic materials and non-metallic materials.

For metallic 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.

  • 1. The first is the requirement for the hardness of the material. For some occasions, the higher the hardness of the material, the better, but it is limited to the hardness requirements of the machined part. 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 moderately soft and hard, 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, 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 great. If the hardness exceeds the hardness of the machine (lathe tool), it cannot be processed. It will only damage the parts, but also cause danger, 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 in order to be processed.
