Diamond tool and manufacturing method thereof

Abstract

The invention discloses a diamond tool comprising a basic body and a diamond layer. A through hole is formed in the basic body, and a water groove is formed in the outer circumference of the diamond layer and communicated with the through hole. In addition, the invention discloses a manufacturing method of the diamond tool. The diamond tool is provided with the water-passing hole, cooling liquid enters from a hole in the bottom of the basic body and is discharged from the water groove in the outer circumference of the diamond layer, and grindings can be sufficiently discharged in time in the process of continuous grinding so that blocking and scratching on the surface of a machined material can be avoided. The diamond tool is rapid in heat dissipation and high in grinding efficiency, the diamond layer and the basic body are firmly combined, the production technology process is easy to operate, and cost is saved. Meanwhile, according to the manufacturing method of the diamond tool, the diamond layer and the basic body are directly consolidated together through high-temperature pressure exertion, while the diamond layer is formed, the diamond layer and the basic body are combined, the diamond layer will not suffer damage caused by secondary heating, and combination strength is higher.

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...
