Kolekcja: Diamond Smoothing Pads

Professional resin bond diamond pre-polishing pads for flat lap machines and polishing systems. The flexible resin bond conforms slightly to surface irregularities for consistent diamond contact across the full pad face. Available in 6"–24" diameters across 60–50,000 grit with magnetic, PSA, and plain backing options — used as the intermediate pre-polish stage between coarse diamond flat lap discs and final polishing compounds on stone slabs, cabochons, glass, and gem materials.

Recommended Workflow

• Stage 1: Coarse grinding with Diamond Flat Lap Discs (60–325 grit)
• Stage 2: Pre-polish with Diamond Smoothing Pads (600–8,000 grit)
• Stage 3: Fine pre-polish with Diamond Smoothing Pads (14,000–50,000 grit) for hard gems
• Stage 4: Final polish with Felt Polishing Pads + Cerium Oxide or Diamond Compound

Frequently Asked Questions

• Q: What is the difference between diamond smoothing pads and diamond flat lap discs?
  A: Diamond flat lap discs use a rigid or semi-rigid metal bond for efficient material removal in coarse grinding stages (60–325 grit). Diamond smoothing pads use a flexible resin bond that provides a softer, more consistent cutting action for pre-polish stages — removing the scratches left by coarse discs and preparing the surface for final polishing compound. Smoothing pads are always used after flat lap discs, never before.
• Q: Which grit smoothing pad should I use before final polishing?
  A: For most lapidary stone and glass work, finish with 3,000–8,000 grit smoothing pads before applying polishing compound on a felt pad. For very hard gem materials (Mohs 8+) or mirror-quality finishes, continue through 14,000–50,000 grit before the final polish stage. The higher the grit you finish with on the smoothing pad, the easier and faster the final polish will be.
• Q: What backing type should I choose — magnetic, PSA, or plain?
  A: Choose magnetic backing if your flat lap machine uses a magnetic backing plate — magnetic pads allow instant disc swapping between grit stages without tools. Choose PSA backing for semi-permanent mounting on PSA backing plates — pads adhere firmly during use but can be peeled off and replaced. Choose plain (no backing) for custom mounting setups or hand lapping applications.
• Q: Can diamond smoothing pads be used on a bench grinder?
  A: Diamond smoothing pads are designed for flat lap machines where the pad rotates horizontally on a flat platen. They are not designed for bench grinder arbor mounting. For bench grinder pre-polish work, use diamond resin soft wheels or REZ wheels instead.
• Q: What diameter smoothing pad do I need?
  A: Match the pad diameter to your flat lap machine's platen size. Common sizes: 6" and 8" for small bench-top flat lap machines, 12" for mid-size production machines, 16"–24" for large production flat lap systems. Always verify your machine's platen diameter before ordering.
