In grinding, EDM process, the workpiece will be some magnetization, has a weak magnetic force, is very easy to suck some small things, so before the assembly, to the workpiece for the demagnetization process, and clean the surface with ethyl acetate. General assembly guide pins and bushings installed first, and then install mold and punch and die, and then to the entire gap, particularly with punch and die gap be adjusted group, to be implemented after completion of the assembly mold testing, write the whole report. The problems found, can reverse thinking method cell curbs child dies, that is a step forward from the step, from finishing to roughing, greening the way the teeth one by one to check the child die, until you find the crux of the problem. Curb mold surface during processing to leave marks, grinding marks are stress concentrated, is the source of crack propagation, which will directly result in the production of concrete curbs will not die so easily stripping, road teeth look ugly child mold, is insufficient. Therefore, after the end of the process, the need for parts for surface hardening, through fitter grinding, dispose of process risks. Some of the side edge of the workpiece, acute, obtuse orifice are inverted, R technology. The method for the surface finish road sub-teeth mold factory, grinding hardened layer is removed.
