The 6" Resin Bond Diamond Pre-Polishing Pad is engineered for high-precision surface smoothing and pre-polishing on gemstones, cabochons, glass, ceramics, and hard mineral specimens. Formulated with a flexible resin-bonded diamond matrix, this pad conforms to both flat and contoured workpieces, eliminating pits, scratches, and subsurface damage left by coarse grinding stages.
Key Features
Flexible Resin Bond Matrix: Conforms slightly to curved surfaces to prevent faceting and edge chipping on cabochon domes and contoured glass.
Rapid Scratch Removal: Efficiently smooths surfaces after metal-bond lap grinding, preparing workpieces for final optical polishing without diamond paste contamination.
Multi-Backing Compatibility: Designed for standard 6" flat lap platens, compatible with Magnetic Backing, Pressure-Sensitive Adhesive (PSA), and Hook & Loop (Velcro) systems.
Broad Grit Versatility: Available across fine pre-polishing grades (60 to 50,000 grit) to complete every stage of surface refinement.
Recommended Applications
Lapidary cabochon smoothing and dome pre-polishing (agate, jasper, quartz, jade, turquoise, opal).
Stained glass, artistic glass sculpture edge smoothing, and bevel refinement.
Precision mineral specimen flattening and preparation for optical microscopy.
Operating Guidelines
Always operate with continuous water cooling to prevent thermal resin degradation and extend disc longevity.
Recommended operational speeds: 400 – 1,000 RPM on standard flat lap machines. Apply light, even pressure.
