3500mmx50mm Multi-Grit Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 3500mm x 50mm Flexible Diamond Sanding Belt (approx. 138" length x 2" width) is an extra-long industrial continuous grinding belt engineered for long-bed stroke sanders, automatic glass arrising machines, and pipe/tube finishing equipment. Premium electroplated industrial diamond crystals bonded securely to a flexible, high-tensile waterproof backing provide concentrated contact pressure, rapid material removal, and extended abrasive life under continuous coolant flow.

Key Features

• Full Range of Grits & Patterns: Available in Dot and Arrow diamond patterns from coarse 60 Grit calibration down to 1800 Grit ultra-fine polishing.
• Extra-Long 3500mm (138") Length: Maximizes thermal dissipation and minimizes heat build-up across continuous industrial production shifts.
• 2" (50mm) Concentrated Face: Ideal for edge profiling, seam arrising, beveling, and cylindrical contour grinding.
• Heavy-Duty Waterproof Backing: Reinforced synthetic backing resists stretching, edge fraying, and moisture fatigue under high tension.
• Precision Low-Vibration Splice: Smooth, reinforced butt joint eliminates vibration and prevents workpiece chatter marks.

Applications

• Architectural flat glass arrising, beveling, and heavy cold-working
• Lapidary cabochon shaping, quartz pre-polishing, and mineral contour finishing
• Granite, marble, engineered quartz countertop edge profiling, and ceramic tile beveling
• Thermal spray coatings, hard facing alloys, and technical ceramics

Operating Guidelines

• Coolant: Always operate with continuous water flood or mist coolant to flush swarf and maximize diamond abrasive performance.
• Tension & Tracking: Verify alignment and run belt on idle before processing workpieces.
• Speed: Recommended surface speed 3,000 to 5,500 SFPM.
