Three ways of grinding with brown fused alumina powder


   1. Wet grinding: Also known as sand-coating grinding, the liquid abrasive is continuously filled or coated on the grinding surface, and the brown corundum or white corundum abrasive continuously slides and rolls between the workpiece and the lap to form a cutting motion. Wet grinding is generally used for coarse grinding, and the fine powder abrasive used has a particle size coarser than W7.

   2. Dry grinding: Also known as sand-embedded grinding, the brown fused alumina or white fused alumina abrasive is evenly pressed into the surface layer of the lap. When grinding, only a small amount of auxiliary materials such as stearic acid mixed fat are applied on the surface of the lap. Dry grinding is often used for fine grinding, and the fine powder abrasive used is finer than W7.

   3. Semi-dry grinding: similar to wet research, the abrasive used is a paste-like paste. Grinding can be done either manually or on a grinder.
