Diamond Coated Grinding Discs: Backing Plate Selection Guide
For optimal performance with diamond-coated grinding discs, choose the appropriate backing system based on your workflow and equipment.
Backing Plate Options
-
Magnetic Backing:
-
Use with Metal Master Laps for instant, tool-free attachment.
-
Ideal for quick disc swaps and heavy-duty grinding.
-
-
Pressure-Sensitive Adhesive (PSA) or Velcro:
-
Pair with Plastic or Aluminum Backing Plates.
-
Perfect for hobbyists or tasks requiring frequent disc changes.
-
-
Non-Backed Discs:
-
Attach directly to custom or existing plates using adhesives.
-
Diamond Disc Features:
- Ultra-Thin Design: 1.0mm diamond-coated surface for precision grinding and minimal material waste.
- Controlled Diamond Concentration: Ensures consistent material removal and smooth finishes.
- Mesh Size Range:
Mesh/Grit |
Application |
---|---|
60–220 |
Rough grinding, rapid stock removal |
325–600 |
Fine grinding, pre-polishing |
1200–3000 |
Ultra-fine finishing, mirror-like surfaces |
Master Lap Compatibility:
Diamond discs can be mounted on:
- Plastic Master Laps: Lightweight and corrosion-resistant.
- Metal Master Laps: Durable for heavy use with magnetic discs.
- Aluminum Backing Plates: Rigid and heat-resistant for precision tasks.
Applications:
- Gemstone Grinding: Shape and refine quartz, sapphire, and other gemstones.
- Lapidary Work: Achieve flat, parallel surfaces on cabochons or faceting rough.
- Commercial Cutting: Efficiently process large volumes of hard materials.
Why Choose Diamond-Coated Discs?
- Versatility: Switch between rough grinding and fine polishing with different grits.
- Durability: Electroplated diamond grit resists wear, even on hardened metals.
- Precision: Flat, rigid backing ensures even pressure for flawless results.
Pro Tips
- Adhesive Care: Clean PSA surfaces with alcohol before reapplying discs.
- Speed Control: Use lower RPM for fine grits to avoid overheating.
- Storage: Keep discs flat and dry to prevent warping.
