Технические характеристики
Advanced Synchronization Technology
In double-gob operations, even a micro-second difference in cut timing can lead to variations in gob temperature and weight. Nexmek blades are ground as a single unit to ensure absolute geometric identity.
- Matched-pair manufacturing for simultaneous gob separation
- Uniform blade tensioning to prevent uneven wear patterns
- Consistent drag-coefficient across all cutting edges
Center Distance & Feeder Compatibility
We provide a wide range of center distance configurations to ensure direct compatibility with your existing feeder setup and shear mechanism.
| Machine Standard | Center Distance | Compatibility |
|---|---|---|
| Small DG | 4 1/4" (108mm) | Standard IS Machines |
| Medium DG | 5" (127mm) | High-Capacity Feeders |
| Large DG | 6" (152mm) | Wide-Body IS Machines |
| Custom | On Request | Specialized Production Lines |
Thermal Management & Spray Retention
Multi-gob cutting generates significant friction and heat. Our DG blades feature a specialized matte surface designed to hold shear spray more effectively than polished alternatives.
- Increased lubricant retention for cooler operation
- Prevents 'glass pickup' and material build-up
- Extends the interval between regrinding cycles
- Reduces the risk of thermal shock on the blade edge
