grinding wheel material:
1. Material types: A, WA, SA, PA, GC, C, 38A, DA, 19A
2, material selection:
A - brown corundum abrasive, brown color, high hardness, high toughness. Suitable for grinding metals with high tensile strength, such as carbon steel, alloy steel, malleable cast iron, hard bronze and so on.
WA-white corundum abrasive, white color, hardness higher than brown corundum, easy to break abrasive particles, sharp edges and corners, good cutting performance, grinding heat is small. Suitable for grinding hardened steel, alloy steel, high speed steel, high carbon steel, thin-walled parts and so on.
SA - single crystal corundum abrasive, the color is light yellow, compared with A, WA abrasive material, high hardness, toughness, single particle spherical crystals, strong anti-crushing. Suitable for wear-resistant steel, high vanadium high-speed steel and other toughness, high hardness materials and easy deformation of the burned parts.
PA - chrome corundum abrasive, color rose or purple, cutting edge sharp, good angular retention, high durability. Suitable for grinding tools, measuring tools, instruments, threads and other workpieces with low surface roughness requirements.
GC - green silicon carbide abrasive, green color, high hardness, brittle, sharp abrasive, with a certain degree of thermal conductivity. Suitable for grinding of cast iron, brass, lead, zinc and rubber, leather, plastic, wood, ore, etc.
C - black silicon carbide abrasive, the color is gray black, high hardness, brittleness, sharp grain, good thermal conductivity. Suitable for grinding cemented carbide, optical glass, ceramics and other hard and brittle materials.
