线切割加工精度日益提高,现已成为冷冲模的主要加工手段之一。但能否用线切割加工作为冷冲模的最后加工工序,以取代设备昂贵的连续轨迹座标磨削?这是很多模具生产厂十分关切和期待解决的问题。为此,本文就其表面质量问题进行了比较系统的试验,在此基础上,分析原因,提出解决途径。 Increasing the accuracy of wire cutting, has become one of the main processing means of cold die. But can we use wire cutting as the last processing step of the cold die to replace the expensive continuous path coordinate grinding machine? This is a lot of mold manufacturers are very concerned about and look forward to solving the problem. For this reason, this article has carried on the comparative systematic test to its surface quality question, on this basis, analyzed the reason, proposed the solution way.
