The coincidence of the rotation axis of the diamond cutting blade grinding wheel indicates the method for adjusting the diamond concentration of the diamond grinding wheel. The diamond abrasive is pre mixed with the filler, which can be salts, glass balls, or magnetic particles. The diamond grinding wheel is made of diamond abrasive as raw material, using metal powder, resin powder, ceramics, and electroplated metal as binders. The circular solid grinding tool with through holes is called diamond grinding wheel (alloy grinding wheel). After bonding, 20% of the filler particles with a thickness are bonded by a metal bond, and these fillers are removed using the following methods: (diamond grinding wheel) dissolution method, sublimation method, or magnetic field (defined as the field that transmits magnetic force between objects) method. In this method, the particle size of the filler is roughly the same as that of the diamond abrasive particle, and the amount of filler used should be able to achieve the specified concentration of diamond on the working surface of the grinding tool. The disadvantage of these methods is that the removal of the filler is relatively complex and requires a specialized set of methods.
What are the methods for adjusting the diamond concentration of diamond grinding wheels? Another relatively simple method for removing fillers is to use spherical particles with a smooth surface. Firstly, the thickness of the metal bond deposited is 20% of the height of the diamond abrasive particles (with sand), and then the filler is brushed off with a brush. After that, the metal bond is continued to deposit to the specified thickness. The hardness of diamond grinding wheels determines the main characteristics of diamond grinding wheels, which can grind difficult to machine materials such as hard alloys, glass, ceramics, etc., and grinding tools have a long service life. The diamond grinding wheel is made of diamond abrasive as raw material, using metal powder, resin powder, ceramics, and electroplated metal as binders. The circular solid grinding tool with through holes is called diamond grinding wheel (alloy grinding wheel). This method utilizes the effect of metal bonding agents having different holding abilities for particles with different surface roughness and shapes. The disadvantage is that the size of the filler particles is similar to that of diamond abrasive particles, so after bonding, they are on the same plane. When using mechanical methods to remove the filler, it is possible to brush off some of the diamond abrasive particles together, especially those particles with similar shapes and smooth surfaces.
