A stone diamond grinding wheel is a specialized abrasive tool designed for grinding, shaping, or polishing hard materials like stone (granite, marble, concrete), ceramics, glass, and even certain metals. Here’s a detailed breakdown:
Key Features:
1. Diamond Abrasives:
– The wheel contains synthetic diamond particles (the hardest known material) bonded to the surface or embedded within the matrix.
– Diamonds provide exceptional durability and cutting efficiency for hard materials.
2. Bond Types:
– Metal Bond: High durability, used for aggressive grinding of granite/concrete.
– Resin Bond: Soother finish, ideal for polishing marble/ceramics.
– Electroplated Bond: Thin diamond layer for precision work (e.g., glass).
3. Segmented/Rim Design:
– Segmented rims (with gaps) reduce heat buildup and improve debris clearance during heavy grinding.
– Continuous rims are used for smoother finishes or cutting.
4. Grit Sizes:
– Coarse grits (e.g., 30–100): Rapid material removal.
– Fine grits (e.g., 200–3000): Polishing/finishing.
Common Applications:
– Stone Fabrication: Shaping edges of countertops (granite/marble).
– Construction: Grinding concrete floors or removing coatings.
– Glass/Ceramics: Precision grinding or bevelling.
Usage Tips:
– Wet vs. Dry Grinding: Some wheels require water cooling to prevent overheating and extend lifespan.
– RPM Compatibility: Match the wheel’s max RPM to your grinder/tool speed.
– Pressure Control: Avoid excessive force to prevent premature wear.
Safety Precautions:
– Wear PPE (goggles, mask, gloves).
– Ensure proper wheel mounting/flange alignment to avoid imbalance.
