There are several points that should be paid attention:

 Concentration selection:

1, when the material is harder to grind, the concentration should be greater;

2, when the grinding area increases, the concentration will decrease;

3, when the grinding pressure increases, the concentration of the microcrystalline abrasive should be increased;

4, when the rigidity of the machine is good, a higher concentration can be used.;

5, when the removal amount is large, we should choose the higher concentration;

Grit selection of the microcrystalline alumina grinding abrasives

Since the microcrystalline alumina grinding abrasive is extremely sharp, it will affect the roughness of the ground workpiece.

According to Norton data in 1988, it recommended that the particle size should be 1 or 2 smaller than the original corundum grinding abrasive.

Hardness selection

When you need to replace the normal alumina grinding wheel with microcrystalline alumina grinding wheel, normally the same hardness grade should be chosen.

Several problems should be paid attention to;

Operators should know the following points :

1, you don’t need a special machine tool, the same machine as the normal corundum wheels;

2, to increase the feed rate, the efficiency is relatively higher than the normal standard corundum;

3, it is necessary to reduce the dressing times of the grinding wheel. Cause its good self-sharpening;

4, when grinding, the sound will be different from that of the ordinary corundum grinding wheels, It sounds like the grinding wheel is too hard.

Some people will think that there may be a problem. But it is not.
