| 摘要 |
A tool component comprising an abrasive element presenting a cutting edge or point and a thermally conductive element having a thermal conductivity greater than the thermal conductivity of the abrasive element, wherein the thermally conductive element is in thermal contact with the abrasive element so as to conduct heat generated at the cutting edge or point away from such cutting edge or point. The thermally conductive element may be bonded to a substrate. The abrasive element may be PCBN and the thermally conductive element may be either CVD diamond or PCD or else the abrasive element may be PCD and the thermally conductive element may be CVD diamond. |
