Influence of Auxiliary Abrasive on the Resin Bond Used in Diamond Tools

Abstract:

The effects on the mechanical properties for three auxiliary abrasive with different hardness were researched by changing the content of the auxiliary abrasives in the phenolic resin-based bond in this paper. The abrasive tool sample's bending strength and Rockwell hardness were tested. It shows that with the increase of TiO₂ content, the hardness and strength reduced firstly, but then increased; and when the content of TiO₂ was 5%, the Rockwell hardness decreased by 30% and the bending strength fell by 44.98%. As the CeO₂ content increases, the hardness of the abrasive tool changed little, while the bending strength decreased more, and when its content was 1%, the bending strength decreased by 25.63%. When the content of SiO₂ is 3%, he bending strength decreased by 32.82%; and when its content is 5%, the Rockwell hardness reduced by 24.97%, and then its hardness has a substantial increase.
