1. The fast cheap metal grinding disc has weak bonding strength, so the self-sharpening property during grinding can be good, it is not easy to block, the grinding efficiency is high, the grinding force is low, the grinding temperature is low, and the disadvantage is that the wear resistance is poor and the wearer wears out. Large, not suitable for heavy duty grinding.
2. Fast cheap metal grinding disc wear resistance and bonding ability is better than resin binder, cutting sharp, high grinding efficiency, not easy to heat and block, less thermal expansion, easy control accuracy, disadvantages grinding surface is thicker, higher cost.
3. Fast cheap metal grinding disc has high bonding strength, good wear resistance, low wear, long service life, low grinding cost and high load, but poor sharpness, and easy blockage.
4. Abrasive grain size has a certain influence on the clogging and cutting amount of the grinding disc. Compared with the fine sand grain, the coarse sanding grain has a larger wear depth of the cutting edge, and the fast cheap metal grinding disc is easy to block.
5. The hardness of the grinding disc has a great influence on the blockage. The high hardness of the grinding disc is high, which is not conducive to the surface heat dissipation, which is beneficial to improve the processing precision and durability.
6. The selection of the fast cheap metal grinding disc concentration is an important characteristic. It has a great influence on the grinding efficiency and the processing cost. If the concentration is too low, the efficiency is affected. On the contrary, the abrasive grains of the fast cheap metal grinding disc is easy to fall off, but the concentration range of the good bonding agent is also good.
