Ceramic bond CBN grinding wheel with cooling groove and R angle and preparation process of ceramic bond CBN grinding wheel

Abstract

The invention discloses a ceramic bond CBN grinding wheel with a cooling groove and an R angle and a preparation technology of the ceramic bond CBN grinding wheel, and relates to the technical field of ceramic bond CBN grinding wheel preparation. The ceramic bond CBN grinding wheel comprises a grinding wheel base body, a grinding wheel block, a cooling groove main body, a bonding tool body and a reinforcing structure; by means of the bonding tool body, when the grinding wheel base body and the grinding wheel block need to be bonded to form the cooling groove body, the threaded jacking column can be rotated to push the polyurethane jacking block to conduct bonding and pressing movement of the grinding wheel block and the grinding wheel base body, and therefore the requirement for subsequent rapid preparation of the cooling groove body is met; the efficient production process of the grinding wheel is formed through the steps of mold design calculation, tool positioning, curing forming and R angle machining, meanwhile, a reinforcing structure is further arranged in the threaded jacking column, in other words, the connecting stability of the threaded jacking column and the polyurethane jacking block is improved through a multi-stage composite structure, and the loosening probability of the threaded jacking column and the polyurethane jacking block is reduced. And the bonding machining effect of the grinding wheel block and the grinding wheel base body is improved.
