830mmx70mm Diamond Flexible Abrasive Finishing Sanding Belts For Polishing Glass Ceramic Porcelain Lapidary and Stone

Overview: The 830mm x 70mm Flexible Diamond Sanding Belt (approx. 32-5/8" length x 2-3/4" width) is engineered for broad contact grinding on specialized bench sanders, wet robotic finishing cells, and wide-platen contour polishers. Industrial electroplated diamond abrasive arranged in open patterns on a flexible waterproof backing delivers aggressive stock removal and durable, cool-running wet operation across hard stone, glass, and ceramics.

Key Features

• Full Range of Grits & Patterns: Available in Dot and Arrow patterns across grit sizes from coarse 60 Grit calibration down to 1800 Grit ultra-fine pre-polishing.
• Wide 70mm Format: Provides expanded contact surface area for fast leveling of broad facets, countertop bevels, and thick glass panels.
• Waterproof High-Tensile Backing: Impervious to continuous water flush and synthetic coolants without swelling, stretching, or edge fraying.
• Precision Butt-Joint Seam: Smooth, seamless joint prevents bumping, vibration, and chatter marks under high work pressure.

Applications

• Glass cold-working, thick architectural glass edge smoothing, and bevel prep
• Lapidary gemstone roughing, large cabochon shaping, and agate slab finishing
• Granite, marble, engineered stone countertop profiling, and porcelain tile beveling
• Thermal spray coatings, hard alloy weld dressing, and ceramic deburring

Operating Guidelines

• Coolant: Use with continuous water mist or coolant spray when feasible to prevent diamond thermal wear and clear swarf.
• Tension & Tracking: Verify alignment and proper machine tension before applying heavy grinding pressure.
• Speed: Recommended surface speed 2,500 to 5,000 SFPM.
