Diamond grinding wheel is a heavy-duty grinding tool used for leveling, smoothing, and removing tough materials like concrete, stone, epoxy, and coatings. It consists of diamond segments bonded to a metal cup-shaped core, providing aggressive material removal with durability.
Key Features & Uses
✔ Material Removal: Ideal for grinding concrete, masonry, stone, and hard coatings.
✔ Segmented Design: Allows airflow for cooling, reducing heat buildup.
✔ Bond Types:
-
Metal Bond – Most durable, for hard concrete and stone.
-
Resin Bond – Smoother finish, for softer materials like epoxy.
-
Hybrid Bond – Balanced performance.
✔ Wet or Dry Use: Some require water cooling (wet grinding), while others are for dry use.
Types of Diamond Cup Wheels
-
Single Row Cup Wheel – Basic grinding, general-purpose concrete work.
-
Double/Triple Row Cup Wheel – More aggressive removal, longer lifespan.
-
Turbo Cup Wheel – Faster cutting with segmented rim, less vibration.
-
PCD (Polycrystalline Diamond) Cup Wheel – For ultra-hard surfaces like polished concrete.
Advantages Over Abrasive Wheels
-
Longer lifespan – Diamonds stay sharp much longer than abrasives.
-
Faster grinding – More efficient material removal.
-
Less vibration – Smoother operation than traditional grinding discs.
Choosing the Right Diamond Cup Wheel
-
For Concrete Grinding: Coarse grit (16-30), metal bond.
-
For Epoxy Removal: Medium grit (50-80), resin bond.
-
For Smooth Finishing: Fine grit (100+), hybrid or resin bond.
-
Wet vs. Dry: Wet grinding reduces dust but requires water; dry is more convenient.
Best Practices for Use
-
Wear PPE (respirator, goggles, gloves) – Silica dust is hazardous.
-
Check RPM Rating – Must match your grinder’s speed.
-
Use Proper Pressure – Let the diamonds do the work; avoid forcing it.
