The machining of cemented carbides after sintering is done mainly by grinding operation. They are very hard and brittle in comparison with high speed steels. Therefore grinding cracks occur easiliy in grinding operation of sintered carbides. Grindability of sintered carbides (JIS.P10,P30,K10,K30) is examined in free infeed plunge-cut grinding with silicon carbide grinding wheel. The results obtained are as follows. 1. Metal removed is more affected by grinding cracks and pitts than hardness of sintered carbides. This is different from the grinding of high speed steels in preoious reports. 2. More wheel wear appears in the grinding of hard sintered carbides. 3. Grinding ratio of P grades is larger than K grades.
