Extend The Service Life Of Resin Diamond Grinding Wheels
May 17, 2018

Extend the service life of resin diamond grinding wheels

Most of diamonds have poor adhesion, the particles will fall off prematurely under external forces during grinding. To a great extent, it affects the use efficiency and its life.

The surface of the resin diamond grinding wheel will have a sharp spiky structure, which means that the surface of the diamond will be roughened, so that well improved the holding power and bonding strength of the diamond by the binding agent. In addition, the diamond plated chemically metal material, the compressive strength will be enhanced about 40~55% than the original. Then it can be reduced high load and the odds that the diamonds fall off under a huge collision. At the same time, Ti, Ni and other metal conduction thermal properties are also very good.They are easy to graphitize the diamond abrasive in high temperature working process, which played a very good resistance to thermal erosion. Although the metal surface coating abrasive on the diamond surface has been greatly improved its life, it also affects its sharpness and increases the manufacturing cost. To improve the sharpness, we usually will add more than 20% TI and Ni coated diamonds to replace the ordinary diamond abrasive. It can significantly increase the life of the grinding wheel and the sharpness.

For the resin bonded abrasive grinding wheel, the appropriate amount of plated abrasives in the bonding agent will play its better role than the ordinary diamond abrasive, and also have a certain degree of protection for ordinary diamond abrasive. The coated abrasive has a good bonding force, heat resistance, pressure resistance. And it is a good support point for the nearby ordinary diamond abrasives, thereby reducing the loss of ordinary diamond abrasives due to poor holding force.

JR company specializes in diamond and CBN tools, including resin bond, vitrified bond, metal bond and electroplated grinding wheel.
