The machining process needs to choose the right tool and machining parameters to avoid problems such as work hardening and surface residual stress.

Precision technology has important influence on forging quality. In the forging process, it is necessary to use high-precision molds and equipment, control the deformation amount and cooling speed and other factors to ensure the dimensional accuracy of the forging and the stability of the internal organization. In the heat treatment process, it is necessary to adopt a suitable heating and cooling system to obtain the ideal grain structure and mechanical properties. In the machining process, it is necessary to use high-precision tools and processing parameters to avoid problems such as work hardening and surface residual stress to ensure the quality and stability of the forging.
