Grinding oil stone
The mainly abrasive material is brown aluminum oxide, white aluminum oxide and silicon carbide.
1.The brown aluminum oxide is high hardness and high toughness. This material oil stone used for high strength metal, such as all kinds of steel, malleable cast iron, bronze, etc.
2.White corundum abrasive hardness is higher than that of brown alumina, toughness lower than that of brown alumina, good cutting performance, this material oil stone suitable for grinding alloy steel, high speed steel, carbon steel, etc.
3.Black silicon carbide abrasive are sharp and crisp, high purity. it is suitable for the grinding of cast iron, non-ferrous metal, rubber, leather, plastic, wood, and non-metallic ore, etc.
