200mmx40mm Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 200mm x 40mm Flexible Diamond Sanding Belt (designed for 200mm / 8-inch diameter expandable rubber drums, 628mm circumference x 40mm width) is engineered for fast stock removal, edge leveling, and precision surface pre-polishing. Electroplated industrial diamond particles bonded to a tear-resistant, flexible backing provide cool cutting and uniform stock removal on hard brittle materials.

Key Features

• Multiple Grits & Patterns: Available in Dot and Arrow patterns across coarse dimensioning to fine polishing grits (60 to 1800 Grit).
• Expandable Drum Fit: Tailored for 200mm (8-inch) expandable rubber drums and expanding wheels (628mm developed length x 40mm width).
• Flexible & Tear-Resistant Backing: Conforms smoothly to curved workpieces, expanding wheels, and contours without cracking or delamination.
• Precision Butt Splice: Smooth, reinforced joint prevents bouncing and chatter during high-speed rotation.

Applications

• Glass cold-working, bottle neck edging, and glass bevel leveling
• Lapidary gemstone rough grinding, cabochon smoothing, and mineral specimen finishing
• Ceramic tile beveling, porcelain edge leveling, and composite finishing

Operating Guidelines

• Coolant: Always run with continuous water flood or mist coolant to flush slurry and prevent diamond thermal wear.
• Mounting: Slide securely over compatible 200mm (8-inch) expanding rubber wheels before startup.
• Speed: Recommended operating speed 2,500 to 5,000 SFPM.
