Green silicon carbide is smelted by resistance furnace at high temperature, suitable for grinding cemented carbide, hard and brittle metals and non-metals. Green silicon carbide grinding wheel is a porous body made by adding binder to abrasive, compacting, drying and calcining. So what are the advantages of green silicon carbide grinding wheels?
Five characteristics of green silicon carbide:
1.The high-purity, large-crystalline silicon carbide raw material ensures the excellent cutting performance and stable physical state of the green silicon carbide cutting powder.
2.The particle size shape is equal area and has a knife edge, which ensures the balanced self-sharpening of the silicon carbide micropowder as the cutting edge material, thereby ensuring the minimum TTV of the material to be cut.

3.The particle size distribution is concentrated and uniform.
4.It has high thermal shock stability and load softening temperature, which ensures a small linear expansion coefficient when cutting under load, thereby ensuring the stability of cutting; and it can be well adapted to the cutting machine.
5.The surface is specially treated, the micropowder has a large specific surface area and a clean appearance, and has a good compatibility with cutting fluids such as polyethylene glycol.
Advantages of green silicon carbide grinding wheel:
1.The abrasive grains are sharp and have high hardness, which can grind hard and brittle materials such as cemented carbide, optical glass, ceramics, and alloys.
2.It is more brittle, so the edges and corners are kept poor, and it is not suitable for machining workpieces with greater toughness.
3.Good thermal conductivity, suitable for grinding workpieces that are easily deformed by heat.
