Research on performance of precision grinding cemented carbidecutting tools with heavy grinding wheel

摘要:
对强力砂轮磨粒晶形，磨削层结合剂成分，砂轮磨损情况，砂轮磨削力以及所磨削的刀具外观质量等方面进行了研究。结果表明：磨削层的结合剂成分会影响砂轮的自锐性；且在相同的磨削条件下，磨粒的晶形不仅直接影响砂轮自身的磨削力和磨损性能，而且决定了所磨削刀具的外观和表面质量。

Abstract:
The grain shape of the heavy grinding wheel, the composition of the grinding layer, the wear of the grinding wheel, the grinding force of the grinding wheel and the appearance quality of the endmill are studied. The results show that the composition of the grinding layer has a effect on the self-sharpening of the grinding wheel. Under the same grinding condition, the crystal shape of abrasive not only affects the grinding force and wear resistance of the grinding wheel itself, but also determines the appearance and surface quality of the solid carbide cutting tools.
