Brown Fused Alumina Oxide Manufacturers Russia

The correct and reasonable selection of the coated abrasive is not only to obtain good brown aluminium oxide grinding processing efficiency, but also to make the coated abrasive itself exert its maximum working efficiency. The chemical composition of artificial abrasives is relatively stable, so the aluminum oxide blasting abrasive hardness is basically the same, and the crystal form is relatively stable.

The main basis for selecting the grinding tool: On the one hand, the fused aluminum oxide grinding machine structure, the physical and mechanical properties of the grinding workpiece, the selection of the grinding parameters, the shape characteristics and processing requirements of the grinding tool must be considered from the conditions of the aluminum oxide abrasive blasting grit grinding process; Characteristics to determine. Workpiece hardness can be greater than 55HRC.


The following briefly introduces the general principles of selection from the three elements of coated abrasives—aluminium oxide blasting grit, matrix and adhesive. Selection of Abrasives There are two main types of abrasives used in making coated abrasives, namely artificial abrasives and natural abrasives. Artificial abrasives are mainly brown corundum, white corundum, knot corundum, and black silicon carbide, and there are also a small number of products for green silicon carbide.


The choice of artificial corundum is mainly determined by the requirements of the workpiece being processed. The selection principle of abrasives for consolidated wheels is also applicable to coated abrasives. Brown corundum is suitable for processing all kinds of carbon steel, alloy steel, malleable cast iron, non-ferrous metals, hard bronze and so on. The hardness of the workpiece is less than 55HRC, synthetic corundum price and the tensile strength is less than 700MPa.


Self-corundum is suitable for brown fused alumina processing hardened steel, high carbon steel, stainless steel and various high hardness alloy steels and non-ferrous metals. Black silicon carbide is suitable for processing low-tensile, tough, golden barriers and non-metallic materials, such as glass, fiberglass, ceramics, wood, particleboard, fiberboard, etc. For example, P16 ~ P24 abrasive tools are used for rust removal of hull steel plates, burring of metal parts, and alumina grit grinding welds.


Similarly, P60 ~ P80 granularity and roughness R are used for external grinding wheels. Chrome corundum is suitable for processing stainless steel, high molybdenum steel, heat-resistant alloy steel, titanium alloy, brass, blue steel, gray cast iron, nickel-chromium alloy, chromium-diamond alloy, tungsten-diamond alloy, etc. In general, when processing similar workpieces, the grinding efficiency of the belt is higher than that of the black aluminum oxide media grinding wheel.


Green silicon carbide is suitable for processing hard and brittle materials, such as hard alloy, glass, jade, single crystal silicon, engineering ceramics, high-grade finish paint, piano panel paint, sewing machine head paint, etc. For workpieces with large machining allowances, coarse grain size should be selected for high grinding efficiency. If the workpiece has a small machining allowance, a aluminum oxide 220 grit abrasive fine grain size should be selected for a low surface roughness value.


Stainless steel surface polishing R.0.8 ~ 0.2 is P60 ~ P100. The brown aluminum oxide surface polishing (Ra 0.025) of stainless steel sheet steel rolls uses W20 grinding tools. In other words, on the one hand, the abrasive grains of the abrasive belt are embedded in the workpiece surface to a greater depth than the grinding wheel; on the other hand, almost all of the abrasive grains arranged neatly on the surface of the aluminum oxide 40 grit belt can perform grinding.
