Sintered carbides are superior in wear resistance to high speed steels, but they are very brittle. Therefore they are apt to be cracked in grinding operation. The grinding cracks are an important factor in grinding sintered carbides. They affect the cutting ability on the one hand, affecting grinding ratio on the other hand. Dry grinding operation of sintered carbides is done with plane grinding machine. The number and the depth of grinding cracks are examined respectively on the ground surface in case of the grinding wheel GC120K9V. The results obtained are as follows. 1. Grinding cracks occur easily in the low toughness sintered carbides, especially in the sintered carbides containing TiC and TaC. 2. The high grade of sintered carbides in more than the low grade in the number of grinding cracks. 3. Grinding cracks of the grade K01,K05 are very deep, the others are shallow.
