刃磨硬质合金车刀,一般经过两道工序。先用氧化铝砂轮(粒度为36～46,硬度为CM_1～C_1)刃磨刀杆的后面;再用碳化硅砂轮(粒度为46～80,硬度为M_2～CM_1)刃磨刀片的后面。目前,大多数工人都使用碳化硅砂轮(粒度为60～80,硬度为CM_1～M_3),在一道工序上刃磨出硬质合金车刀的主后面。这时由于砂轮的轨迹垂直干刀片的切削刃,容易使切削刃产生细小的缺口。在刃磨之后,必须迸行仔细的研磨,否则就会减短车刀的寿命。为了提高刃磨的生产率,省去比
Sharpening carbide lathe, usually after two processes. Grinding the back of the sharpener with alumina grinding wheel (particle size of 36-46, hardness of CM_1 ~ C_1) and grinding the back of the blade with silicon carbide grinding wheel (particle size of 46-80, hardness of M_2 ~ CM_1). At present, most workers use carbide wheel (particle size 60-80, hardness CM_1-M_3) to sharpen the main back of the carbide tool in one operation. At this moment, the cutting edge of the dry blade is perpendicular to the path of the grinding wheel, so that a slight nick is easily generated in the cutting edge. After sharpening, careful grinding must be performed or the life of the turning tool will be reduced. In order to improve the productivity of sharpening, save more than
