To determine the use of CNC handboard model processing mode, it is necessary to determine the installation of the handboard base, processing base, processing margin, let CNC processing technology advantages get full play.

The more complex hand plate in the processing process will occur hot deformation, after quenching will produce internal stress, after the hand plate compression will also appear deformation. It is very difficult to make a complex hand plate at one time, which can be divided into two or more clamping. Processing procedures to follow the principle of gradual refinement by rough.

The use of large flow cooling, can reduce the processing of a large number of heat produced on the impact of processing accuracy, in order to improve the wear of the tool, also need to use large flow cooling.
