大家都认为磨硬质合金刀具应使用绿色碳化矽砂轮而不用黑色碳化矽砂轮,这是有理由的。黑色碳化砂磨粒在磨削力作用之下比较不易破裂,因此它的切削刃不会愈磨愈锐利,反而愈磨愈钝。这样造成以下的缺点:砂轮面上磨擦加大,热度加高,容易糊住;工件表面上出现裂纹与焦皮,生产率降低 We all think that carbide cutter carbide should be used instead of black silicon carbide wheel, which is justified. Black carbide abrasive particles in the grinding force under the relatively hard to rupture, so it will not be cutting edge grinding more sharp, but more abrasive blunt. This resulted in the following disadvantages: grinding wheel surface friction increased heat higher, easy to paste; cracks and coking surface of the workpiece, reduce productivity
