Diamond polishing wheel

CMG1827

Diamond polishing wheel is a precision tool used to grind, hone, and polish hard materials like stone, glass, ceramics, and metals to a high-gloss finish. These wheels are embedded with diamond abrasives in various grits and bonds to achieve different levels of refinement.

Key Features & Uses

✔ High-Shine Finishing: For granite, marble, quartz, glass, and engineered stone.
✔ Progressive Grit Levels:

• Coarse (50-200 grit) – Removing scratches, shaping.

• Medium (200-800 grit) – Smoothing surfaces.

• Fine (800-3,000+ grit) – Mirror-like polishing.
  ✔ Bond Types:

• Resin Bond – Most common, flexible for fine polishing.

• Metal Bond – Durable, for aggressive grinding before polishing.

• Hybrid Bond – Combines durability with smoothness.

Types of Diamond Polishing Wheels

1. Rigid Polishing Pads – For flat surfaces (granite slabs, countertops).

2. Flexible Backing Pads – Conforms to curves (sink holes, edges).

3. Electroplated Diamond Wheels – Thin coating for precision work (gemstones, glass).

4. Velcro-Backed Discs – Easy to replace, used with rotary tools.

Best Applications

• Stone Fabrication: Polishing countertop edges, sink cutouts.

• Glass & Ceramics: Beveling, lens polishing.

• Metals & Composites: Deburring, finishing aerospace parts.

Choosing the Right Polishing Wheel

• For Granite/Marble: Start with metal-bond (50-400 grit), finish with resin-bond (800-3,000 grit).

• For Glass/Ceramics: Use electroplated or resin-bond fine grits (1,500+).

• For Metals: Diamond-impregnated felt wheels for mirror finishes.

Polishing Process (Step-by-Step)

1. Grind First – Use a coarse diamond wheel (50-200 grit) to remove imperfections.

2. Hone – Progressively smoother grits (200-800) to eliminate scratches.

3. Polish – Fine grits (1,500-3,000+) with water or polishing compound for shine.

Pro Tips

• Use Water Cooling – Prevents overheating and extends wheel life (for stone/glass).

• Match RPM to Wheel Type – High speed for coarse grit, slower for fine polishing.

• Clean Between Grits – Avoid cross-contamination of abrasive particles.
