Vitrified bond diamond grinding wheel is a grinding tool which is made by mixing ceramic or glass as bond with diamond abrasive. The diamond abrasive and Vitrified or glass are firmly bonded through molding process and heat treatment process.

A variety of new materials continue to emerge with the development of science and technology. In a sense, the level of mechanical processing restricts the full use of new materials. Machining is evolving in the direction of high efficiency, high precision, low loss, and automation. Ceramic bond diamond grinding tools are the product of this development. The application range is more and more extensive, and the number of applications is increasing year by year in the world. Diamond grinding tools are mainly used for cutting, grinding or polishing of cemented carbide, ceramic and refractory materials, glass, graphite, gemstones, non-ferrous materials and non-metallic materials, etc.

The use of Vitrified bond diamond grinding wheels in sharpening PCD tools is also becoming more widespread. PCD tools have the characteristics of high hardness and high wear resistance, which makes it difficult to sharpen such tools. To process PCD tools, we must first select high-hardness abrasive tools. Diamond is the hardest substance in nature. so ceramic bond diamond grinding wheels have a series of advantages such as high hardness, high strength, high temperature resistance, chemical resistance and good self-sharpness. Therefore, the grinding tools for sharpening PCD tools are mainly ceramic bond diamond grinding wheels.

In summary, the Vitrified bond diamond grinding tools have the following advantages for grinding PCD tools.

1、The vitrified bond diamond grinding wheels have high wear resistance and low wear rate.

2、The grinding temperature is low, and the grinding force is small. The grinding tool is easy to be trimmed, and the grinding efficiency is high.

3、The surface of the ground workpiece has good quality, high precision and good shape retention.

Vitrified bond diamond grinding wheel has more and more obvious advantages in the grinding process of hard tools such as PCD tools, and it has a good application prospect in the development of diamond grinding tools.
