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