A kind of diamond tool and its manufacturing method

Abstract

The invention discloses a diamond tool, which comprises a matrix and a diamond layer. There is a through hole in the matrix, and a water groove is formed on the outer circumference of the diamond layer, and the water groove communicates with the through hole. In addition, the invention discloses a method for manufacturing a diamond tool. The diamond tool of the present invention has a water hole, and the cooling liquid enters from the bottom hole of the base body and is discharged from the outer circular water tank of the diamond layer. During the continuous grinding process, the grinding debris can be discharged in time to avoid clogging and damage to the processed product. Scratches occur on the surface of the material, and the heat dissipation is rapid, the grinding efficiency is high, the diamond layer and the substrate are firmly bonded, the production process is simple to operate, and the cost is saved. Consolidation together, the diamond layer and the matrix are simultaneously combined during the forming process of the diamond layer, so that the secondary heating of the diamond layer will not be damaged, and the bonding strength is stronger.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to a diamond tool and a manufacturing method thereof. Background technique [0002] In the prior art, diamond tools are similar to this kind of grinding tool. During continuous grinding, the grinding debris cannot be discharged in time, which will cause blockage, material burns, and even scratches on the surface of the processed material; the tool design mostly adopts external circulation The coolant plays the role of chip removal and cooling, that is, only grooves are made on the outer circle or end face of the gold layer; the groove shape manufacturing process of the diamond layer is processed by electric shock with an EDM machine tool, which will burn the diamond layer and cause the diamond to fall off, which will affect The performance of the diamond layer increases the cost; for diamond grinding head tools, the diamond layer is mostly welded to the substrate by high-frequency...
