Precision machining requirements for certificates Not all raw materials can be used for precision machining. Some raw materials are too hard, which may exceed the hardness of the machined parts, which may break the machine parts. Therefore, these raw materials are not suitable for precision machining, unless they are made of special materials. Into the machine parts, or laser cutting. The raw materials for precision machining by precision machining manufacturers are divided into two categories, metal raw materials and non-metal raw materials. For metal raw materials, the hardness is greater than stainless steel, followed by cast iron, followed by copper, and then aluminum. The processing of ceramics, plastics, etc. is attributed to the processing of non-metallic raw materials. Precision machining mainly puts forward requirements for the hardness of the certificate Read more
