The sizes of grinding machine plates (also known as grinding discs or wheels) vary depending on the type of grinding machine and its application. Here are common sizes for different types of grinding machines:
1. Bench Grinder Wheels
– Diameter: 6″ (150mm), 8″ (200mm), 10″ (250mm)
– Thickness: 1/2″ (12mm) to 1″ (25mm)
– Arbor Hole Size: 1/2″ (12.7mm), 5/8″ (15.875mm), or larger for industrial models
2. Angle Grinder Discs
– Diameter:
– Small: 4.5″ (115mm), 5″ (125mm)
– Medium: 6″ (150mm), 7″ (180mm)
– Large: 9″ (230mm)
– Thickness: Typically around 1/8″ to 1/4″ (3–6 mm) for cutting discs, thicker for grinding discs
3. Surface Grinding Machine Wheels
– Diameter: Typically 6–12 inches (150–300 mm) for smaller machines, up to 24 inches (600 mm) for larger industrial grinders
– Width: Varies from 0.5–2 inches (12–50 mm)

4. Cylindrical Grinding Wheels
– Used for precision grinding of cylindrical parts; sizes vary widely:
– Diameter: 8–20 inches (200–500 mm) or more
– Width: Up to several inches depending on workpiece size
5. Centerless Grinding Wheels
– Larger wheels used in high-pr.jpg)
ction grinding:
– Diameter: Often 12–36 inches (300–900 mm)
Key Considerations When Choosing a Grinding Plate/Disc:
– Material Being Ground: Metal, concrete, stone, etc.
– Machine Compatibility: Check arbor size and max RPM rating.
– Grit Size: Coarse grits (~24–60) for heavy material removal; fine grits (~80+) for finishing.
