光整加工作为模具加工的最后一道工序 ,其加工质量一般影响着产品的最终质量和使用性能 .尽管模具加工的大部分工序实现了自动化 ,但模具光整加工的自动化却一直无法实现 ,其加工工作量要占整个工作量的 30 %～ 40 % ,严重制约着生产的发展 .磁粒光整加工技术的出现 ,为模具光整加工自动化的实现带来了希望 Finishing As the last step in mold processing, the quality of the processing generally affects the final quality and serviceability of the product.Although most processes of mold processing are automated, the automation of mold finishing has been unimaginable and its processing The work load accounts for 30% ~ 40% of the total work load, which seriously restricts the development of production. The emergence of magnetic particle finishing technology brings the hope for the automation of mold finishing.
