Surface Grinding Wheel Specification – Precision & Performance by Hindustan Abrasives

Surface grinding wheels are essential tools in precision machining, used to achieve smooth finishes, tight tolerances, and accurate dimensions on a variety of materials. At Hindustan Abrasives, Surface Grinding Wheel Specification tailored for different industrial applications, ensuring efficiency, durability, and superior grinding performance.

Key Specifications of Surface Grinding Wheels

The specifications of a surface grinding wheel are determined by several critical factors:

1. Abrasive Type

Surface grinding wheels are made using different abrasive materials, each suited for specific applications:

• Aluminum Oxide (A) – Ideal for grinding ferrous metals, steel, and cast iron.

• Silicon Carbide (C) – Best for non-ferrous metals, ceramics, and glass.

• CBN (Cubic Boron Nitride) – Preferred for hardened steel and superalloys.

• Diamond Abrasives – Used for carbide, glass, and high-hardness materials.

2. Grit Size

The grit size of a grinding wheel determines the finish quality and material removal rate:

• Coarse Grit (8-24) – Fast material removal but rough finish.

• Medium Grit (30-60) – Balanced removal rate with a finer finish.

• Fine Grit (70-220) – Best for ultra-smooth surface finishes.

3. Bond Type

The bond holds the abrasive grains together and affects wheel performance:

• Vitrified Bond (V) – High strength, durability, and precision grinding.

• Resinoid Bond (B) – Good for high-speed grinding and soft materials.

• Metal Bond (M) – Best for diamond and CBN wheels, ensuring long life.

4. Hardness Grade

The hardness of a wheel impacts how quickly abrasive grains break down:

• Soft Grade (E-H) – Suitable for hard materials and fast cutting.

• Medium Grade (I-P) – Ideal for general-purpose grinding.

• Hard Grade (Q-Z) – Used for soft materials requiring slower wear.

5. Structure & Porosity

The wheel structure determines the spacing between grains:

• Open Structure – Enhances coolant flow and chip clearance.

• Dense Structure – Provides a finer finish with more cutting points.
