Precautions for materials for precision parts machining

Precision mechanical parts processing, not any material can be precision processing, some materials hardness is too large, across the hardness of the machine parts, may break the machine parts, so these materials are not suitable for precision machining, unless it is made of special materials, or laser cutting. So what are the material requirements for…
