Before machining parts, be sure to pay attention to the density of the material. If the density is too high, it is equivalent to a great hardness. If the hardness exceeds the hardness of the lathe tool, it cannot be processed, which will not only damage the parts, but also cause danger. For example, the knife flies out and hurts people. So, what are the precautions for the material processing of parts?

The materials for parts processing are divided into two categories, metallic materials and non-metallic materials. For metal materials, the hardness is stainless steel, followed by cast iron, followed by copper. The processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials.
