Rubber Diamond Grinding
Engineered for high-efficiency polishing of dental prostheses, the Rubber Diamond Grinding integrates advanced materials and precision engineering to deliver dry-processing solutions for zirconia, precious metal alloys, ceramics, and resin workpieces. Its medical-grade silicone matrix is uniformly embedded with 20–50 μm diamond particles, enabling three-layer grinding (coarse grinding, contour refinement, and mirror polishing) without water cooling. The temperature rise is controlled at ≤3°C (at 20,000 RPM), eliminating thermal damage risks to restorations.

Advantage
1. Advanced Dry-Grinding Technology
- Waterless Operation: Proprietary heat dissipation channels reduce friction-induced temperature rise to ≤3°C at 20,000 RPM, enabling safe dry processing of zirconia/ceramics.
- Multi-Layer Diamond Matrix:
- 50 μm Coarse Layer: Achieves 0.2–0.3 mm/s material removal rate (lab-tested on zirconia blocks).
- 20 μm Medium Layer: Refines contours with Ra 0.5 μm surface roughness.
- 5 μm Polish Layer: Delivers mirror finishes (Ra ≤0.1 μm) in a single tool.
2. Enhanced Durability & Material Innovation
- Synthetic Diamond Reinforcement: Grade 6 industrial diamonds (1100GPa hardness) ensure 3x lifespan vs. resin-bonded alternatives (60+ restorations/bur) .
- Uniform Abrasive Distribution: Electrostatic bonding technology prevents diamond shedding (<0.01% loss after 50 cycles) .
3. Workflow Optimization
- Time Efficiency: Completes crown adjustments in 2–3 minutes (vs. 5–8 mins for water-cooled systems) .
- Ergonomic Compatibility: 45° angled head design facilitates access to posterior implant prostheses (compatible with NSK/Bien Air handpieces) .
4. Cost-Effective Performance
- Reduced Consumable Costs: 60% lower replacement frequency compared to conventional burs.
- Multi-Material Adaptability: Single tool handles zirconia crowns, lithium disilicate margins, and PMMA dentures, reducing inventory needs.
