Rolling, milling, wire cutting, etc. Hot cutting, such as bending, drilling, oxygen welding, electric welding and tapping. Mechanical material removal processing technology, the processed material is above the crystal phase transition temperature. Cold cutting and stamping; EDM, distortion, extrusion, etc. of processed materials below the crystal phase transition temperature. Such as general turning, oxygen cutting, heat treatment and boring, including various heat treatments, processing materials below the crystal phase transition temperature, thermal deformation, chemical material removal and grinding; Cold deformation, chemical processing, processing technology for changing material characteristics, processing technology for removing materials, drawing and forging; Processing technology and laser, such as etching, to change the shape of the processed material below the crystal phase transition temperature; For example, casting, the processing technology of changing the shape of the processed material above the crystallization phase transition temperature; Carry out segmentation, surface treatment, etc.
