Abstract
In order to explore the effect of fine powder on the performance of metal bonded grinding wheel, the fine powder and ordinary powder with different ratios were mixed homogeneously and were made into matrix body-blocks by hot pressure sintering method.Moreover, superabrasive were added to the above mixed powder and were made into metal bonded superabrasives.By employing the sclerometer, the bending test machine, the scanning electron microscopy, the cutting machine and so on, we tested the hardness of metal bond matrix, the bending strength, the fracture morphology and the cutting performance respectively.The results show that fine powder is favorable to raise the bending strength of metal bond matix and the maximum increase is 20%, and that it also increases the wear resistance of superabrasives, with radius abrasion reduced by 25.7% at the same conditions.关键词
