模具型腔的光整加工一直是模具加工中的重要难题之一,目前我国在这方面尤其落后,多采用手工方法,加工效率极低,经试验研究证明,采用电化学抛光的方法,能有效地解决模具型腔抛光的难题,使抛光效率比手工方法提高几十倍以上。 用电化学抛光金属零件的方法虽早已被人们所知,但抛光模具型腔在国内尚未采用过。本文发表了对CrWMn,3Cr2W8V和Cr12等三种材料模具的抛光试验。实验结 Mold cavity finishing has always been one of the most important problems in mold processing. At present, China lags behind in this respect, using more manual methods and with extremely low processing efficiency. The experimental studies have shown that electrochemical polishing can be effective To solve the problem of mold cavity polishing, polishing efficiency than the manual method to improve several times. Electrochemical polishing of metal parts has long been known, but the mold cavity has not been used in China. This article published on the CrWMn, 3Cr2W8V and Cr12 three kinds of material mold polishing test. Experimental results
