Grinding wheel is a multipoint cutting tool having abrasive particles bonded together and so forming a structure.
Generally abrasive properties like hardness, toughness and resistance to fracture uniformly abrasives are classified into two principal groups:
Natural abrasives: The natural abrasives are emery and corundum. These are impure forms of aluminium oxide.
Artificial abrasives: Artificial abrasives are silicon carbide and aluminium oxide.
  • Silicon Carbide: It is less hard than diamond and less tough than aluminium oxide. It is used for grinding of material of low tensile strength like cemented carbide, stone and ceramic, grey cast iron, copper, brass, bronze, aluminium, vulcanized rubber, etc.
  • Aluminium Oxide: Aluminium oxide is tough and fracture resistant. It is preferred for grinding of materials of higher tensile strengths like steel; high carbon and high-speed steel and tough bronze.

Silicon Carbide Abrasive for Grinding

Silicon carbide (SiC) is a popular abrasive material that is used for various grinding applications. It is known for its hardness, strength, and ability to withstand high temperatures. The silicon carbide abrasive is used primarily for grinding cemented carbide, ceramic, and cast iron materials.

Grinding Cemented Carbide
- Cemented carbide, also known as tungsten carbide, is a composite material widely used in the manufacturing industry for its high hardness and wear resistance.
- Silicon carbide abrasive is an excellent choice for grinding cemented carbide due to its hardness and ability to maintain sharp cutting edges.
- The abrasive grains of silicon carbide help in removing the excess material from the carbide surface, resulting in the desired shape and finish.
- Grinding cemented carbide with silicon carbide abrasive ensures precise and efficient material removal, making it an ideal choice for applications such as tool and die making, cutting tools, and wear parts.

Grinding Ceramic
- Ceramic materials are known for their high hardness, brittleness, and resistance to wear and corrosion.
- Silicon carbide abrasive is well-suited for grinding ceramic materials due to its exceptional hardness and ability to maintain its shape and sharpness during the grinding process.
- Silicon carbide abrasive grains are effective in removing material from ceramic surfaces, resulting in smooth finishes and precise dimensions.
- Grinding ceramics with silicon carbide abrasive is commonly used in industries such as automotive, aerospace, and electronics for applications involving ceramic components, cutting tools, and wear-resistant parts.

Grinding Cast Iron
- Cast iron is a widely used material known for its high strength, durability, and wear resistance.
- Silicon carbide abrasive is suitable for grinding cast iron due to its hardness and ability to withstand the high temperatures generated during the grinding process.
- The abrasive grains of silicon carbide efficiently remove material from the cast iron surface, resulting in the desired shape, surface finish, and dimensional accuracy.
- Grinding cast iron with silicon carbide abrasive is commonly used in industries such as automotive, construction, and machinery manufacturing for applications involving cast iron components, engine parts, and machine tools.

Conclusion
The silicon carbide abrasive is versatile and widely used for grinding cemented carbide, ceramic, and cast iron materials. Its hardness, strength, and ability to withstand high temperatures make it an excellent choice for precision grinding applications in various industries.
