等离子加热切削是七十年代初期出现的一门加热切削加工技术。它主要用于高强度、高硬度、高韧性的难加工材料的切削加工,具有明显的技术经济效果。据报导,英、美、日等国家已对二十多种难切削材料进行等离子加热切削试验,并用于生产,工效普遍提高,最高的提高工效达24倍。我们从1974年开始等离子加热切削实验,先后对ZGMn、GC—4、冷硬铸铁、63甲焊条堆焊层等难加工材料进行等离子加热切削的实验,取得了较好的效果。1976年曾先后在沈
Plasma heated cutting is a heated cutting process that began in the early 1970s. It is mainly used for high-strength, high hardness, high toughness of the difficult processing of materials cutting, with obvious technical and economic results. It is reported that Britain, the United States, Japan and other countries have more than 20 kinds of hard cutting materials for plasma heating cutting test, and for the production, efficiency generally increased, the highest efficiency up to 24 times. We started the plasma heating cutting experiment in 1974, and we succeeded in the plasma heating cutting experiments on ZGMn, GC-4, chilled cast iron, and 63-A electrode surfacing layer, and achieved good results. 1976 has Shen
