Main Features
- Micron-Level Precision Machining: Manufactured to industry-leading flatness and runout tolerances, ensuring uniform cutting pressure across the entire blade circumference.
- Mirror-Polished Cutting Edge: Ultra-smooth edge finish prevents material adhesion and tearing, critical for slitting delicate copper foil and thin films.
- Premium Tungsten Carbide Option: Tungsten carbide blades provide longer service life than tool steel blades for high-volume copper foil slitting.
- Full dynamic balancing: All blades undergo precision dynamic balancing in accordance with G1.0 standards to ensure vibration-free operation at high speeds.
- Precision Mounting System: Accurately machined bores and keyways ensure perfect alignment with slitter arbors, eliminating blade slippage.
Advantages
- Flawless Slit Quality: Guaranteed burr-free, straight edges on all thin materials, eliminating secondary finishing operations and improving product marketability.
- Exceptional Edge Retention: Advanced material and heat treatment processes significantly extend blade life, reducing the frequency of blade changes.
