After selecting the raw material, it is calcined at a high temperature of about 1000° for a sufficient time, and then cooled at an appropriate speed. The purpose is to reduce hardness, improve machinability; eliminate residual stress, stabilize size, reduce deformation and crack tendency; refine grain, adjust structure, and eliminate structure defects.
