When grinding various grades of high-speed steel, the abrasive must have:

(1) The hardness must be higher than the hardness of the carbide which accounts for a large proportion in the high-speed steel being ground.

(2) In the process of grinding high temperature and severe extrusion, the abrasive should have certain strength and toughness.

When grinding wheels with different abrasives, the results obtained are different when grinding various new high-speed steels. It can be seen that the grindability of high-speed steel with vanadium content of about 1% and 2% is better than that of high-vanadium high-speed steel with vanadium content of 3% and 4%. Under the same grinding conditions, the grinding performance of the single crystal corundum wheel is better than that of the Cuqin corundum, which is due to

The single crystal corundum abrasive has a medium volume and a multi-angular cutting edge, so the abrasive cutting edge has a long life, and the grinding amount is large over time. The grinding wheel wears less, the grinding ratio is high, and the geometric shape retention performance is good. However, the proportion of isocratic abrasive grains in Cochin corundum abrasives is small, and there are many needle-shaped abrasive grains. The abrasive grains are easy to break during grinding, the cutting edge is difficult to maintain, and the grinding wheel wears large. When using cubic boron nitride (CBN) abrasives to grind high-speed steel with a vanadium content of 2%, the grinding ratio is 4 to 7 times higher than that of single crystal corundum. Especially when the vanadium content of the workpiece material is 3% and above, it shows the superiority of cubic boron nitride abrasive. Its grinding ratio is 5-30 times higher than that of single crystal corundum and 15-40 times higher than that of complex-sensitive corundum.
