Abrasive wear is the most common wear form of resin grinding wheel cutting disc. During the cutting process, the abrasive grains on the grinding wheel are in constant contact and friction with the workpiece material, causing the abrasive grains to gradually wear and become blunt, weakening the cutting ability. This wear form will reduce the grinding efficiency of the grinding wheel and may lead to a decrease in the quality of the grinding surface.
Grinding wheel breakage refers to the shedding of abrasive grains or grinding blocks on the surface of the resin grinding wheel cutting disc. This is usually caused by excessive grinding force or uneven internal stress of the grinding wheel. Breakage will cause depressions on the surface of the grinding wheel, affecting the grinding balance, further leading to uneven grinding and reduced processing accuracy.
Grinding wheel blockage refers to the blockage of the pores of the grinding wheel by the chips or grinding powder of the workpiece. Blockage not only reduces the grinding ability of the grinding wheel, but may also cause burns on the surface of the workpiece. This situation is particularly obvious when processing soft materials.
The high temperature generated during the grinding process will cause the hardness of the grinding wheel abrasive grains to decrease, especially in the absence of effective cooling. This thermal wear will cause the grinding wheel abrasive grains to lose their cutting ability and accelerate overall wear.
In a high temperature environment, the abrasive material of the grinding wheel may react chemically with oxygen in the air, causing the abrasive to oxidize. This oxidative wear will further weaken the hardness and durability of the grinding wheel.
During the use of the grinding wheel, mechanical damage may occur due to external impact or improper operation during installation and transportation. Mechanical damage will cause cracks or breakage of the grinding wheel, and in severe cases, it may cause the grinding wheel to break or fail.
During repeated grinding operations, the bonding force between the bonding agent of the grinding wheel and the abrasive will gradually weaken, causing the abrasive to fall off and accelerating the wear of the grinding wheel. This wear pattern is particularly obvious under long-term high-load operation.
