Abstract: Targeting the shortcomings of a conventional push bench roller die pass processing and repairing method,a multi-function CNC pass processing machine for CPE push bench roller die is developed.The working procedure,structure and characteristics of the machine is detailed.This newly-developed muti-fuction CNC pass processing machine for CPE push bench roller die can realize a continuous working procedure on various sizes of roller dies,doing over-all turning,precise pass processing and chamfering.The machine will significantly shorten the roller die pass processing and repairing time,dramatically increase the working efficiency,decrease the number of assemblying and disassemblying personnel and the area of working place,and lower the consumption of lubricating grease and spare parts.
