利用高温等离子弧加热切削是七十年代发展起来的新技术,目前,英国处于领先地位,我国正在试验研究和初步应用这一新技术。这种加工方法的主要特点是适用于高硬度、高强度和一般刀具不能切削的工件,同时还可提高切削工效,如加热切削高锰钢工件,可提高效率10倍多,加热切削钴基合金粉末(Co—A)喷焊层(HRC=56～59),提高效率8倍左右。
The use of high-temperature plasma arc heating cutting is developed in the seventies new technology, at present, Britain is in a leading position, our country is experimenting with the initial application of this new technology. The main features of this processing method is suitable for high hardness, high strength and general cutting tools can not be cutting the workpiece, but also can improve the cutting efficiency, such as heating and cutting high manganese steel parts, can improve the efficiency of 10 times, heating cutting cobalt-based alloy Powder (Co-A) spray coating (HRC = 56 ~ 59), improve efficiency about 8 times.
