When purchasing CNC Angle steel punching machine Some details need attention, and a small detail may affect the NC angle steel Punching machine The service life of the machine is the polishing of the machine's steel plate. Some people may think that as long as the mold is ready, there will be no problem. It is not important whether the steel plate is ground or not, but in fact, this is not the case. If the steel plate under the mold is ground unevenly, it is likely to affect the service life of the mold, so that failure may occur in the future use process. We know that the angle steel punching machine will vibrate during operation, which is common sense. However, many people do not pay enough attention to the friction phenomenon caused by the loosening of the mold and the lower steel plate. After the loosening of the abrasive tools, some will use steel plates to pad under the mold, but this cannot solve the fundamental problem, which needs to be paid enough attention 。
