Explain the characteristics of aluminum oxide grinding wheels.

• Low strength, softness, and poor heat resistance. Suitable for grinding glass, ceramics, and other non-ferrous materials.

• Medium strength, moderate hardness, and average heat resistance. Suitable for grinding plastic, wood, and other non-metallic materials.

• High flexibility, low hardness, and poor heat resistance. Suitable for grinding diamonds, gemstones, and other precious materials.

• High strength, hardness, and heat resistance. Suitable for grinding steel, iron, and other ferrous metals.

Describe the applications of silicon carbide grinding wheels.

• No benefits at all

Describe the features of rubber bond grinding wheels.

• No elasticity, no self-sharpening, and no impact on surface finish

• Medium elasticity, average self-sharpening, and inconsistent surface finish

• Low elasticity, poor self-sharpening, and rough surface finish

• High elasticity, good self-sharpening, and good surface finish

How do metal bond grinding wheels differ from other types?

• Metal bond grinding wheels use rubber as the bonding agent.

• Metal bond grinding wheels are made of wood.

• Metal bond grinding wheels do not use any bonding agent.

• Metal bond grinding wheels use metal as the bonding agent.
