深切缓进给磨削通常是在一次切深2～20毫米、工件进给速度5～309毫米/分的磨削用量下,对工件进行磨削的。当磨削条件或磨削用量选择不当时,常常会由于磨削弧区的高温作用引起工件表面发生严重烧伤,甚至使磨削过程无法进行。在深切缓进给外圆磨削的研究工作中,我们采用半人工热电偶法对45钢和球墨铸铁磨削时的磨削温度进行了测试和研 Deep slow feed to the grinding is usually a depth of 2 to 20 mm, the workpiece feed rate of 5 to 309 mm / min grinding amount of the workpiece grinding. When the grinding conditions or the amount of grinding inappropriate choice, often due to the high temperature arc grinding caused by the workpiece surface serious burns, and even the grinding process can not be carried out. In the study of deep grinding for cylindrical grinding, we used semi-artificial thermocouple method to test the grinding temperature of 45 steel and ductile iron grinding
