27 July 2025
Diamond Glass Cutting Wheels: Precision Tools for Modern Industries  
 
Diamond scribing wheels deliver unmatched precision in glass processing. Their superior hardness and wear resistance make them essential for advanced applications like LCD panels, touchscreens, and automotive glass.  
 
 
6 Key Diamond Wheel Classifications  
 
1. High-Penetration Diamond Wheels  
   - Features: Controlled vertical crack depth  
   - Applications: High-end LCD panels, substrate glass, automotive thin glass  
 
2. Micro-Tooth Diamond Wheels
   - Features: Flawless cutting lines, damage-free sections  
   - Applications: Ultra-thin TFT panels (pressure-resistant certified)  
 
3. Standard Diamond Wheels  
   - Subtypes: Double-sided polished / Double-sided matte (economy)  
   - Applications: LCDs, substrate glass, touchscreens, automotive glass  
 
4. Economy Diamond Wheels  
   - Advantages: Extended lifespan, premium cut quality, cost-effective  
   - Benefit: Combines diamond performance with alloy wheel affordability  
 
5. Composite Diamond Wheels  
   - Features: 3x longer lifespan than alloy wheels, high ROI  
   - Applications: Mid-range LCDs, substrate glass (≤5mm thickness)  
 
6. Tooth Profile Classification  
   - Toothless (True-Round) | U-Shape | V-Shape | DBT (concave design by Nihon Kenko, Japan)  
 
 
Tooth Profile Comparison  
Performance varies by geometry for different glass types:  
 
Profile Material Angle/Gear Penetration Specs (D×H×T mm) Lifespan
Toothless Diamond + Tungsten Carbide Angle: 100-160° Minimum 2.5×0.8×0.65 ~100,000m
U-Shape Diamond + Tungsten Carbide
Angle: 100-160°
Gears: 110-360
Medium 2.0×0.8×0.65 20,000-60,000m
V-Shape Diamond + Tungsten Carbide Angle: 100-160° Moderate 2.0-3.0×0.8×0.65 20,000-50,000m
DBT
Diamond Sintered
Angle: 100-160°
Gears: 120-600
Maximum 2.0/3.0×0.8×0.65 ~150,000m
