Black Aluminum Oxide 70 Grit Abrasive Media Suppliers

There are many kinds of brown fused aluminum oxide grinding wheels. According to the abrasives used, it can be divided into ordinary abrasives (corundum silicon carbide, etc.) and superhard abrasives (diamond cubic boron nitride, etc.); according to the shape, it can be divided into flat wheel, bevel wheel, cylindrical wheel, cup wheel, disc wheel, etc.; according to the alumina grit bond, it can be divided into ceramic wheel, resin wheel, rubber wheel, metal wheel, etc.

The characteristic parameters of brown aluminum oxide grinding wheel mainly include abrasive, viscosity, hardness, binder, shape, size, etc. Since the grinding wheel usually works at a high speed, it is necessary to carry out a rotation test (to ensure that the grinding wheel will not crack at the highest working speed) and a static balance test (to prevent vibration of the machine tool during operation) before use. After working for a period of time, the black silicon carbide grinding wheel shall be trimmed to restore the correct geometry of grinding performance.

(black aluminum oxide 70 grit abrasive media suppliers)For everyone's safety, here are the precautions for use: these white alumina problems are directly related to the personal safety of every employee, so we must pay enough attention to the actual use. Precautions during use, side grinding problems: in the daily use of the grinder, we can often find that the operator, regardless of the type of grinder or the type of aluminum oxide grit grinding wheel, grinds the side of the grinding wheel at will, which seriously violates the safety operation rules and regulations.

According to the regulations, it is not suitable to use the brown fused alumina side grinding wheel to make the working surface with the circular surface. This kind of grinding wheel has a large radial strength and a small axial strength. When the operator uses too much force, it will cause the green silicon carbide grinding wheel to break and even hurt people. Positive operation problem: in daily use, many operators are used to operating in the direction of the grinding wheel.(black aluminum oxide 70 grit abrasive media suppliers)

The use of pink aluminum oxide grinding wheel is dangerous. In fact, this kind of behavior should be specially prohibited. According to the operation regulations, when grinding the workpiece with a grinder, the operator shall stand on the side of the grinding wheel, not on the front of the grinding wheel, so as to avoid personal injury when the grinding wheel flies out or breaks. This kind of aluminum oxide abrasive behavior should be prohibited in the actual use process. The surface layer is cold hardening. 

(black aluminum oxide 70 grit abrasive media suppliers)Force operation problem: when the white corundum grinder is used, some operators, especially young operators, use too much force to achieve fast grinding speed, which is an extremely unsafe operation. Any grinding wheel has a certain strength, which is likely to cause the grinding wheel to break, even fly out and hurt people, which should also be prohibited. It is the basis of ensuring the surface quality of workpieces to formulate scientific and reasonable technological silicon carbide abrasive procedures.
