3000x200mm 1200Grit Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 3000mm x 200mm 1200 Grit Flexible Diamond Sanding Belt is crafted for industrial wide-belt sanders, automated glass arris profiling lines, and slab polishing machines. Electroplated 1200-grit fine diamond abrasives distributed across a flexible waterproof backing eliminate scratches from earlier grinding stages to produce a refined, smooth pre-polish surface across wide workpieces.

Key Features

• Fine 1200 Grit Pre-Polish: Blends transitions and removes sub-surface abrasions, smoothing surfaces in preparation for high-gloss buffing.
• Substantial 200mm Working Width: Broad surface area provides steady, uniform contact without grooving or uneven edge wear.
• Waterproof High-Tension Backing: Retains dimensional stability, flexibility, and tracking under continuous water flush and high mechanical tension.
• Precision Butt-Joint Seam: Minimizes joint impact, eliminating surface chatter marks during continuous high-speed passes.

Applications

• Architectural flat glass arrising, tabletop edge pre-polishing, and decorative glass finishing
• Granite, marble, engineered quartz, and porcelain slab edge and surface prep
• Lapidary gemstone slab polishing, mineral specimen prep, and display boulder finishing
• Silicon carbide, technical ceramics, thermal spray coatings, and composite material prep

Operating Guidelines

• Coolant: Always operate with continuous water flood to prevent heat buildup and maintain free-cutting diamond exposure.
• Tension & Tracking: Ensure proper tracking and calibrated tension on wide-span rollers before applying workload.
• Speed: Recommended surface speed 3,000 to 5,500 SFPM.
