What are the three basic raw materials used in the manufacture of coated abrasives?
Grain – a synthetic or natural abrasive; Bond – an adhesive that permanently bonds the backing to the abrasive; Backing – a backing that the abrasive is bonded to

TAOANG Industrial is headquartered in Zhengzhou, Henan Province. The factory is located in Henan Sanmenxia corundum Industrial Park. In 2007, the partners jointly built the Sanmenxia Xinfeng Abrasives Factory, which is mainly engaged in producing and processing brown fused alumina. In 2018, Taoang Industry continued to make a white fused alumina factory in Zhaigen Industrial Park, Sanmenxia City, mainly engaged in producing and processing white fused alumina, dense fused, and bubble alumina.

Aluminum Oxide – Aluminum Oxide is brown or reddish in color and a man-made abrasive. It is durable with tough cutting edges. It offers long life and is highly wear resistant even under stress applications. Its applications include aluminum, ferrous metals (including alloy steel), hardwood, and leather. Crocus – Crocus
Glue – A system where both coats are made of animal glue is used when the strength of the bond is not an important factor, such as with lightweight papers and materials. Phenolic Resin – This system uses full phenolic resin for both coats. It is designed to withstand moisture
Abrasive grains – usually aluminum oxide or silicon carbide Bonding agent – usually a resin bond Spacing of grains within the bond – determine porosity and strength

If you are roughing, choose a 36 to 80 grit. If you are intermediate grinding, use 80 through 180 grit. If you are finishing, use 220 through 240 grit.
The best way to have abrasive products retain maximum performance and work life is to store them properly. The bonding and backing materials used in abrasives are very sensitive to changes in temperature and humidity. Abrasives are best stored at temperature levels of 60 to 80 degrees Farenheit and a
A typical grinding wheel specification consists of the grit type, the grit size, the hardness, the structure and the bond. A typical grinding wheel specification would be A60-I10-VS. ‘A’ is the grit type (aluminum oxide), ’60’ is the grit size, ‘I’ is the relative hardness, ’10’ is the structure, and
Grit type is either aluminum oxide (white, pink, ruby red, brown, grey, etc.) silicon carbide (black or green), ceramic (blue and pink) or any combination of these. Grit types are sometimes mixed in combination for achieving certain cutting characteristics. Aluminum oxide is friable (white) or semi-friable (pink, brown and grey, red,
Grit size typically runs from coarse (16 -24 grit), medium (36 – 60 grit) and fine (80-120 grit). Superfine grits run from 150 and higher. Grinding wheels usually will be between 24 and 100 grit. Honing stones and jointing stones and other polishing abrasives will be 150 grit and higher.
Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond for steel would be in the ‘F, G or H’ range. A
