pink fused aluminaiswhite fused aluminawith chrome oxide (under 0.5% cr2o3) has been added in the fusion process to produce a grain that is slightly tougher than regularwhite fused aluminaused for grinding unhardened high alloy steels. If more chrome oxide (about 3% cr2o3) has been added to, it will get ruby fused alumina, which provides additional toughness overpink fused alumina.

the raw material and refining work ofpink aluminum oxideare basically the same as white aluminum oxide. They are both needed to add cr203 and well mixed to be refined as abrasives with rose red color. Its hardness is close to white corundum, and the roughness is higher than white aluminum oxide. It is suitable for grinding knifes, measuring tools, meters, screw etc. That require low roughness.

most grinding wheels are made with vitrified bonds, which consist of a mixture of carefully selected clays. At the high temperatures produced in the kilns where grinding wheels are made, the clays and the abrasive grain fuse into a molten glass condition. During cooling, the glass forms a span that attaches each grain to its neighbor and supports the grains while they grind.

aluminum oxide is the most common abrasive used in grinding wheels. it is usually the abrasive chosen for grinding carbon steel, alloy steel, high speed steel, annealed malleable iron, wrought iron, and bronzes and similar metals. there are many different types of aluminum oxide abrasives, each specially made and blended for particular types of grinding jobs. each abrasive type carries its own designation-usually a combination of a letter and a number. these designations vary by manufacturer.

adiamond grinding cup wheelis a metal-bondeddiamond toolwithdiamond segmentswelded or cold-pressed on a steel (or other metal, such as aluminum) wheel body, which usually looks like a cup. diamond grinding cup wheels are usually mounted onconcrete grindersto grind abrasive building materials like concrete, granite and marble.

there are various styles and specifications of diamond grinding cup wheels to fit various application requirements. the ones with many big diamond segments can undertake heavy workloads, for example, grinding concrete and stone, while those with small or sparse diamond segments are normally used for fast removal of paints, wallpapers, glues, epoxy and other surface coatings.

just like other metal-bonded diamond tools, the diamond segments on diamond grinding cup wheels can have different bonds, different diamond grits, different diamond quality and different diamond concentrations to fit different uses. for example, if the material to be ground is hard, the bond should be softer, and if the material is relatively soft, the bond should be harder.

diamond grinding cup wheels are used in different-roughness grindings. for coarse grinding, the bond should be softer and the diamonds' quality should be higher, because in this case the diamonds become blunt more easily. the diamond grit should be bigger, normally from 35 grit to 50 grit. for this is coarse grinding and big grit can improve working efficiency. the diamond concentration can be lower.

for fine grinding (sometimes called "polishing"), the bond should be harder and the diamonds' quality can be lower, as in this case the diamonds can last longer and a hard bond can also help the precision of the process. the diamond grit is normally between 80 grit and 120 grit, depending on the grinding requirements. the diamond concentration should be higher.

after being ground, the material can be further polished with resin-bonded diamond polishing pads of different diamond grits.
