3000x200mm 1800Grit Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 3000mm x 200mm 1800 Grit Flexible Diamond Sanding Belt is crafted for high-performance industrial wide-belt sanders, automated glass edging machines, and stone slab polishing equipment. Featuring electroplated 1800-grit ultra-fine industrial diamond crystals evenly bound to a heavy-duty waterproof backing, this belt delivers an exceptionally smooth, uniform fine-polish luster across large glass sheets, stone panels, and hard composite workpieces.

Key Features

• Ultra-Fine 1800 Grit Polishing: Delivers superior surface refinement, eliminating sub-surface microscopic scratches and prepping materials for a mirror gloss.
• Wide 200mm Commercial Span: Ample working surface covers large areas smoothly without line marks or surface unevenness.
• Waterproof Heavy-Duty Backing: Engineered for continuous wet processing under high mechanical tension and sustained water flush.
• Seamless Butt Joint: Precision vulcanized joint ensures quiet, chatter-free operation and seamless tracking at high belt speeds.

Applications

• Architectural flat glass arris polishing, thick glass tabletop edge finishing, and decorative glass prep
• Granite, marble, engineered stone, and quartz slab high-luster surface and edge polishing
• Gemstone slab polishing, large specimen faceting, and mineral display prep
• High-density ceramic substrate finishing, optical glass prep, and tungsten carbide polishing

Operating Guidelines

• Coolant: Always operate with continuous water flow or synthetic coolant to protect diamond bond integrity and flush fine polishing swarf.
• Tension & Tracking: Verify alignment and calibrate belt tension on wide-span rollers before starting production runs.
• Speed: Recommended surface speed 3,000 to 5,500 SFPM.
