6" x 1-1/2" 1200 Grit Diamond Resin Grinding Wheel – Nova Soft Wheel for Precision Glass & Stone Grinding

The 6" x 1-1/2" 1200 Grit Diamond Resin Grinding Wheel (Nova Premium Soft Wheel) is an industry-standard lapidary soft grinding wheel engineered for ultra-fine surface pre-polishing, sub-micron scratch elimination, and satin luster development on gemstone cabochons, glass cold work, and mineral specimens. Built with premium resin-bonded diamond abrasives uniformly dispersed over a resilient closed-cell foam cushion mounted on a heavy-duty balanced plastic hub, it effortlessly conforms to curved stone surfaces to eliminate flats and chatter marks.

Key Features

• Resilient Foam Cushioning: Conforms smoothly to cabochon contours, preventing flat spots and ensuring uniform surface contact across all curved workpieces.
• Ultra-Fine 1200-Grit Diamond Formulation: Produces a silky, semi-gloss pre-polish finish, preparing workpieces directly for final mirror polishing.
• Heavy-Duty Precision Plastic Hub: Precision molded plastic core ensures smooth, vibration-free operation at standard cabbing speeds.
• Standard 1-1/2" Working Width: Fits standard 6-inch cabbing machine arbor shafts and multi-wheel setups.
• Superior Wet Grinding Performance: Engineered for continuous water coolant operation to maintain cool cutting and prevent resin glazing.
• Standard 1" Arbor with Reducer Bushings: Precision 1-inch bore supplied with reducer bushings to fit 3/4", 5/8", and 1/2" shafts.

Applications

• Lapidary Cabochon Contouring: Ultra-fine pre-polishing on agate, jasper, jade, quartz, turquoise, and petrified wood.
• Glass Cold Working & Beveling: Semi-gloss pre-polishing and edge refinement on decorative glass and crystal sculptures.
• Ceramic & Specimen Prep: Precision satin finishing on ceramics and mineral display pieces.

Operating Guidelines

• Always operate with continuous water lubrication to flush slurry and prevent thermal damage to the resin matrix.
• Apply light, uniform pressure across the wheel face; excessive force causes premature wear without improving finishing rate.
• Move workpieces continuously across the wheel to ensure even surface wear and maintain concentric wheel balance.
