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

  1. Magnetic Backing:

    • Use with Metal Master Laps for instant, tool-free attachment.

    • Ideal for quick disc swaps and heavy-duty grinding.

  2. Pressure-Sensitive Adhesive (PSA) or Velcro:

  3. Non-Backed Discs:

    • Attach directly to custom or existing plates using adhesives.

Diamond Disc Features:

  1. Ultra-Thin Design: 1.0mm diamond-coated surface for precision grinding and minimal material waste.
  2. Controlled Diamond Concentration: Ensures consistent material removal and smooth finishes.
  3. 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:

  1. Plastic Master Laps: Lightweight and corrosion-resistant.
  2. Metal Master Laps: Durable for heavy use with magnetic discs.
  3. Aluminum Backing Plates: Rigid and heat-resistant for precision tasks.

Applications:

  1. Gemstone Grinding: Shape and refine quartz, sapphire, and other gemstones.
  2. Lapidary Work: Achieve flat, parallel surfaces on cabochons or faceting rough.
  3. Commercial Cutting: Efficiently process large volumes of hard materials.

Why Choose Diamond-Coated Discs?

  1. Versatility: Switch between rough grinding and fine polishing with different grits.
  2. Durability: Electroplated diamond grit resists wear, even on hardened metals.
  3. Precision: Flat, rigid backing ensures even pressure for flawless results.

Pro Tips

  1. Adhesive Care: Clean PSA surfaces with alcohol before reapplying discs.
  2. Speed Control: Use lower RPM for fine grits to avoid overheating.
  3. Storage: Keep discs flat and dry to prevent warping.
