Ultra-Precision Resin Diamond Polishing Disc | Sub-Nanometer Surface Finishing Lap for Optical Glass & Sapphire
R&D engineered specifically for the ultra-precision surface finishing and mirror polishing of hard and brittle materials—including optical glass, sapphire (LED substrates & smartphone camera cover glass), quartz crystals, semiconductor substrates, and advanced technical ceramics.
Formulated with high-purity micro-grade synthetic diamond/CBN abrasives and a specialized high-performance elastic resin bond, this disc achieves sub-nanometer surface roughness (Ra 0.01–0.05μm) and ultra-high surface flatness.
Featuring superior elastic buffering, rapid heat dissipation, and exceptional polishing efficiency, it effectively prevents micro-scratches and thermal damage, satisfying the most stringent surface quality standards of the global optics and semiconductor industries.
1. Product Overview
In advanced manufacturing sectors like precision optics, 3C consumer electronics, semiconductor wafer substrates, and high-end sensors, creating defect-free, scratch-free, and distortion-free mirror surfaces is paramount. Traditional rigid polishing pads or free-abrasive slurries often present significant pain points: slow processing speed, high slurry waste, uneven wear, micro-scratches, and severe thermal deformation during extended polishing cycles.
Zhengzhou Guantong’s Ultra-Precision Resin Diamond Polishing Disc provides an ideal fixed-abrasive polishing solution. By embedding tightly graded diamond/CBN micro-powders inside an engineered elastic resin matrix, the disc balances aggressive micro-cutting action with soft, responsive compliance. The flexible matrix absorbs microscopic peak loads to eliminate surface scratches and subsurface lattice damage, while the porous resin structure promotes coolant flow and heat evacuation. This ensures stable batch-to-batch consistency, ultra-high surface flatness, and significantly reduced overall polishing costs.
2. Core Technical Advantages
- 1. Sub-Nanometer Surface Roughness Ra 0.01–0.05μm
Achieves ultra-smooth surface finishes with a roughness down to Ra 0.01–0.05μm and high interferometric flatness (within 3 fringe lines), delivering optical-grade mirror surfaces. - 2. Superior Elastic Buffering & Zero Micro-Scratches
The specialized elastic resin matrix absorbs impact forces and distributes pressure evenly across delicate substrates, preventing edge chipping and orange-peel micro-scratches on sapphire and glass. - 3. Excellent Thermal Dissipation & Cool Running
Formulated with heat-dissipating organic resins and structured cooling channels, the wheel keeps operating temperatures low to eliminate thermal stress cracks and optical distortion. - 4. High Polishing Efficiency & Long Tool Life
Controlled self-sharpening matrix continuously exposes fresh micro-diamond cutting edges, providing faster stock removal rates than conventional polishing pads and extending service life by 3–5 times.
