KIND OF ABRASIVE MATERIALS Abrasive materials Tools made by “ANDRE” contain modern, hard abrasive materials.
1.Aluminum oxide (synthetic corundum).
2.αAl2O3 Aluminum oxide in different variations is the most frequently used abrasive material. It is melted from bauxite or aluminium oxide at temp. over 2000ºC in electric furnaces.
3.95A - Normal aluminium oxide (brown) It is prepared from bauxite. Contains 96% Al2O3~3% titanium dioxide (TiO2) and 1-2% other admixtures. It is the most resistant synthetic corundum and is characterized by its high ductility. It is used for cutting-off and rough grinding of low-alloy steels, stainless steels, cast iron, especially for high rates of stock removal.
4.97A - Semifriable aluminium oxide (grey) It is prepared from calcinated bauxite with aluminium oxide addition. Contains 98% Al2O3 corundum and is characterized by medium hardness and strength. It is used for precision grinding and tool grinding.
5.99A - Friable aluminium oxide (white) It is prepared from pure aluminium oxide. It is the purest synthetic corundum and contains over 90 % Al2O3. It is characterized by its high hardness and brittleness. It is used for precision grinding, e.g. surface and cylindrical grinding, sharpening of cutting tools.
6.CrA - Chromium aluminium oxide (pink) It is prepared from aluminium oxide with an addition of up to several percent of chromium oxide. It is characterized by its high hardness and higher strength in comparison with white aloxite. It is used for precision grinding of high-alloy steels, sharpening of cutting tools.
7.M - microcrystalline fused alumina (grey) It is prepared from bauxite by reduction process. Contains over 99% Al2O3. It is characteri¬zed by its high microhardness and mechanic strength and has an excellent self-sharpening ability. It is used for grinding of high-alloy high-speed steels and sharpening of tools. Excellent for grin¬ding of complex profiles.m
8.ZrA - Zirconia aluminium oxide It is prepared from aluminium oxide or bauxite with an addition of zirconium dioxide.
Widely used in fields such as soft magnetic materials, bearings, blades, tools, measuring tools, automobiles, railways, etc
BOSDI produces double-sided convex grinding wheels, single-sided convex grinding wheels, single-sided concave grinding wheels, double-sided concave grinding wheels, single-sided bevel grinding wheels, and double-sided bevel grinding wheels. These anisotropic grinding wheels are mainly used for metal surface processing and edge dressing of diamond grinding wheels. Their characteristics are high correction accuracy, fast correction speed, sharp grinding, high mechanical strength, and strong self sharpening ability. They are used for grinding alloy steel, high-speed steel, and mold steel.
*Suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze, and other bearings, automotive parts.
*Suitable for grinding various types of high-speed steel circular pipes.
*Can be used for various mold steel chrome plated steel heat treatment workpieces.
*Common to various materials and cutting tools.
BOSDI PVA centerless grinding wheel, centerless grinding: shock absorber piston rod, locomotive front fork inner tube, steering gear rod, rocker arm rod, engine valve, nitrogen cylinder, gas spring, nitrogen spring, printer shaft core, various rods in oil pressure parts, various pipe fittings in photocopiers, chromium plated rods, which are used for surface treatment and precision polishing of flat Metalloid, and materials include high carbon steel, high nickel alloy, stainless steel, watch case and stainless steel wheel rim, Circular saw, metal groove.
1040 centerless grinding wheel. 1050 centerless grinding wheel, 1080 centerless grinding wheel.
Characteristics of centerless precision grinding wheels
1. Centerless precision grinding wheels are composed of abrasives, thermosetting resins, and a large number of micro pores. Grinding wheels have the characteristics of elasticity and multiple holes.
2. It can provide a large cutting amount and a uniform surface grinding effect. It can be applied in automated polishing operations, thereby reducing precision grinding time and subtracting some processing steps.
3. The grinding operation can be carried out continuously for a long time, but it will not generate too much grinding heat and blockage.
4. It can be applied to the grinding of materials with different hardness, and has excellent results in grinding from curved surfaces to special metals.
The use of centerless precision grinding wheels
Suitable for precision and ultra precision grinding of cylindrical workpieces on various centerless grinders. For example: shock absorber piston rod, locomotive front fork inner tube, steering gear rod, rocker arm rod, engine valve, nitrogen cylinder, gas spring, nitrogen spring, various rod parts in printer shaft, hydraulic parts, various pipe fittings in photocopier, chrome plated rod, etc.
The domestic centerless grinding wheel is characterized by instability and varying internal and external hardness. Causing great trouble to grinding.
BOSDI company produces centerless precision grinding wheels that can replace Japanese UB wheels and nylon wheels. Stable and reliable quality. Polishing of front shock absorber rods, piston rods, motorcycle front fork pipes, valves, etc. before and after plating.

The production technology and process of synthetic diamond are becoming more and more mature. China's output of synthetic diamond accounts for more than 90% of the world's total output of synthetic diamond, and has become the largest producer of synthetic diamond in the world. As the quality of domestic products is difficult to meet the industry standard of diamond cutting line and the output of refined nickel is insufficient, most manufacturers rely on foreign imports. The following is an analysis of the current situation of the diamond industry.
