Brown corundum abrasives are made of bauxite, anthracite and iron filings as the main raw materials. They are brown in color and have good toughness. silicon carbide Their microhardness is 1800-2200kg / mm2, and their bulk density is more than 3.85g/cm3. They can be used as refractories and abrasives. What are the characteristics of brown corundum abrasive processing workpiece?
The force of the workpiece is easy to analyze. For the traditional free brown fused alumina abrasive grinding, the abrasive is dispersed on the grinding plate and the movement is random. The size and direction of the grinding force of brown corundum abrasive on the workpiece are also random, which makes the folding brown. The force of corundum abrasive on the workpiece is very difficult. Therefore, no one has discussed the force of brown fused alumina abrasive on the workpiece. In the high speed grinding of consolidated brown fused alumina abrasive, the brown fused alumina abrasive moves with the grinding tool, and the law of motion is known. This provides a necessary condition for us to study the force of brown fused alumina abrasive on the workpiece.
The density distribution of brown fused alumina abrasives is controllable. In the free brown corundum abrasive grinding, brown fused alumina powder abrasives are randomly distributed on the grinding disc and change with the movement of the grinding disc. Therefore, the density distribution of brown fused alumina abrasive is uneven and uncontrollable. In the consolidation of brown fused alumina abrasives, brown fused alumina abrasives are bonded to many points on the grinding disc, and the density distribution of brown fused alumina abrasives is controllable.
High grinding speed and high grinding efficiency. In the free brown corundum abrasive grinding, because the brown fused alumina abrasives are scattered on the grinding plate, the grinding speed can not be too fast to avoid the splash of brown corundum abrasive There are interaction forces and relative motion, which leads to the cutting effect between brown fused alumina abrasives, that is, brown fused alumina abrasives grind brown fused alumina abrasives, which increases the waste of brown fused alumina abrasives, which makes the grinding process low and the processing cost high.
