In high speed grinding of consolidated brown fused alumina abrasive, the brown fused alumina abrasive moves together with the grinding tool and the laws of motion are known. This provides the necessary conditions for us to study the force of the brown fused alumina abrasive on the workpiece.
Workpiece forces are easily analyzed. For traditional free brown fused alumina abrasive grinding, the abrasive is dispersed on the grinding disc and the motion is random. The magnitude and direction of the grinding and cutting force of the brown corundum abrasive on the workpiece are also random, which makes the folds brown. The force of the corundum abrasive on the workpiece is very difficult. Therefore, no one has discussed the force of brown fused alumina abrasives on the workpiece.
The density distribution of the brown fused alumina abrasive is controllable. In free abrasive grinding, brown fused alumina abrasives are randomly distributed on the grinding disc, which changes continuously with the movement of the grinding disc, so the density distribution of brown fused alumina abrasives is uneven and uncontrollable. In the consolidation of the brown fused alumina abrasive, the brown fused alumina abrasive is bonded to many points of the disc, and the density distribution of the brown fused alumina abrasive is controllable.
The grinding speed is fast and the grinding efficiency is high. In the free abrasive grinding, since the brown fused alumina abrasive is discretely distributed on the grinding disc, the grinding speed cannot be too fast to avoid the splash of the brown corundum abrasive, and the brown fused alumina abrasive has an interaction during the grinding process Force, and there is relative motion, resulting in a cutting effect between brown fused alumina abrasives, that is, brown fused abrasives grind brown fused alumina abrasives, which increases the waste of brown fused alumina abrasives, which makes the grinding process low, Processing costs are high.
