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