diamond grinding wheels, cutting tools
A diamond sanding abrasive belt is a kind of coated abrasive tool, which is superhard material (synthetic diamond) abrasive particles adhesive to the flexible base by the bond.

Bonded Type and Characteristics Analysis
Electroplated Bond Diamond Abrasive Belt
Diamond particles are bonded on the required coated pattern by nickel plating, which forms a sharp abrasive layer with a very strong grinding force.
Resin Bond Diamond Abrasive Belt
The resin bond is divided into flexible and hard resin according to the degree of hardness.
With good softness and flexible coated patterns, the flexible resin can better fit the surface of the workpiece and has better polishing performance. Because the resin is soft, wear is faster, and the temperature resistance is poor, it is not suitable to make coarse grit-sized abrasive belts. While the flexible resin sanding abrasive belt must be for wet grinding, which also restricts the application under certain conditions.
Thus, compared with the flexible resin, the wear resistance of hard resin is obviously improved, and the temperature resistance is better. Therefore, hard resin diamond sanding abrasive belts can dry grinding to meet the processing requirements of water-proof and oil-proof products. Thicker resin abrasive layers make a sanding belt to be various meshes, forming the system application from rough to finish grinding. But hard resin belt is not relatively flexible and suitable for a roller with a larger diameter, especially for thermal spray coating industry grinding.
Performance of Electroplated and Resin Diamond Sanding Abrasive Belt
CBN Abrasive Belt
The hardness of the CBN abrasive belt is lower than that of the diamond abrasive belt (CBN: 7000-9000; diamond: 8000-10000). But the thermal stability of a CBN abrasive belt is much higher than that of a diamond abrasive belt, especially when machining iron group metal elements, it has good chemical inertia (diamond abrasive in high temperature during grinding iron group elements makes diamond carbonize easily), and it is not easy to bond
