Diamond grinding wheel

CMG1822

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

1. Single Row Cup Wheel – Basic grinding. general-purpose concrete work.

2. Double/Triple Row Cup Wheel – More aggressive removal. longer lifespan.

3. Turbo Cup Wheel – Faster cutting with segmented rim. less vibration.

4. 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.
