How to choose diamond grinding wheel?

How to choose diamond grinding wheel? Diamond grinding wheels are circular bonded abrasive tools with a through hole in the center made of diamond abrasives and metal powder, resin powder, ceramics and electroplated metal as binders. Next, let’s learn about the selection method of diamond grinding wheel. [Diamond grinding wheel selection] How to choose a diamond grinding wheel How to choose a diamond grinding wheel

Diamond grinding wheels are special tools for grinding hard alloy, glass, ceramics, gemstones and other high-hard and brittle materials.

How to choose diamond grinding wheel?

1. The bonding strength of resin bonded diamond grinding wheels is weak, so they can have good self-sharpening properties during grinding, are not easy to block, have high grinding efficiency, low grinding force, and low grinding temperature. The disadvantages are poor wear resistance and abrasive tool loss. Large, not suitable for heavy duty grinding.

2. The wear resistance and bonding ability of ceramic bonded diamond grinding wheels are better than those of resin bonded ones. They have sharp cutting, high grinding efficiency, less heat and clogging, less thermal expansion, easy to control accuracy, but have the disadvantages of rough grinding surface and higher cost. .

3. Metal bond diamond grinding wheels have high bonding strength, good wear resistance, low wear, long life, low grinding cost, and can withstand large loads, but have poor sharpness and are prone to clogging.

4. The particle size of the abrasive has a certain impact on the clogging of the grinding wheel and the cutting amount. Compared with fine sand, coarse sand has a large cutting depth and the cutting edge wear increases. On the contrary, the grinding wheel is prone to clogging.

5. The hardness of the grinding wheel has a greater impact on clogging. A high hardness grinding wheel has a high thermal conductivity, which is not conducive to surface heat dissipation and is conducive to improving processing accuracy and durability.

6. The selection of grinding wheel concentration is an important characteristic. It has a great impact on grinding efficiency and processing cost. Too low a concentration affects efficiency. On the contrary, the abrasive grains are easy to fall off, but the optimal binder concentration range is also the best.

Diamond grinding wheel classification

According to the bond, diamond grinding wheels can be divided into: resin bond diamond grinding wheels; ceramic bond diamond grinding wheels; metal bond diamond grinding wheels (bronze bond diamond grinding wheels)

According to the production process, diamond grinding wheels can be divided into: sintered diamond grinding wheels (resin bonded diamond grinding wheels; ceramic bonded diamond grinding wheels; metal bonded diamond grinding wheels); electroplated diamond grinding wheels; brazed diamond grinding wheels.

According to the grinding method, diamond grinding wheels can be divided into: diamond grinding wheels for grinding diamonds; diamond grinding wheels for grinding carbide (diamond knife grinding wheels); diamond grinding wheels for grinding diamond composite sheets; centerless grinding diamond grinding wheels for coreless grinders; and grinding ceramic products. Use diamond grinding wheels; diamond grinding wheels for cutting (also known as diamond cutting blades); diamond saw blades.

According to appearance or shape, diamond grinding wheels can be divided into: parallel grinding wheels; cylindrical grinding wheels; cup-shaped grinding wheels; bowl-shaped grinding wheels; dish-shaped grinding wheels; edge grinding wheels; grinding discs, etc.
