DRESSING OF CORUNDUM WHEEL WITH POLY CRYSTALLINE DIAMOND

Wheel dressing is an important part of grinding, it influences not only the grinding quality ofthe workpiece,but also the cost of grinding.At present the single point mined diamond is widelyused as dresser in industry.Because the mined diamond is rare in nature and dear,it has a practicalsignificance to find a substituting material for the mined diamond.Due to the isotropy of PCD(polyerystalline diamond),new sharp cutting edges will expose continuously during dressing opera-tions,maintaining high dressing efficiency.Tests show that dressing corundum wheel,especiallydressing those for internal grinding,PCD dresser is suitable to common hardnesses,and grains ofwheels and smaller depth of dressing.The authors consider that PCD dressing can be used to sub-stitute completely the mined diamond dresser and the cost of dressing may be reduced.
