A set of upper and lower carbide blades specifically designed for high-precision slitting processes of lithium battery electrodes, capacitor electrodes, and other similar materials. With their ultra-high hardness, exceptional wear resistance, and superior thermal stability, these blades meet the stringent requirements of new energy materials for burr-free, delamination-free, and highly consistent cutting, making them a key industrial tool for improving battery energy density and safety.
Blade assembly components: | Core Functions: | Technical Features: |
|---|---|---|
Upper blade (moving blade) | Active cutting to create the initial incision | Ultra-smooth cutting edge (Ra ≤ 0.1μm), precisely optimized cutting angle |
Lower blade (fixed blade/bottom blade) | Supporting material for precise shearing | High-rigidity base material, ensuring vibration-free and deformation-free cutting process |
Blade assembly matching system | Precise alignment and gap control of the upper and lower blades | Micron-level gap adjustment, guaranteeing cutting edge quality and tool life |
• Surface Finish: Cutting edge roughness Ra ≤ 0.1μm
• Cutting Accuracy: Slitting width tolerance ±0.01mm
• Applicable Materials: Positive and negative electrode sheets (coated aluminum foil/copper foil), separators, capacitor electrode foils
• Cutting Effect: Effectively eliminates defects such as coating peeling, burrs, and wavy edges
• Service Life: 8-10 times longer than ordinary high-speed steel tools
1. Zero-defect cutting: Mirror-finish cutting edges and precise gaps eliminate burrs and micro-cracks on the electrode sheets from the source.
2. Ultra-high wear resistance: The hard alloy substrate easily handles highly abrasive materials such as ceramic coatings.
3. Excellent stability: Superior thermal stability ensures consistent cutting performance during long-term continuous production.
4. Low maintenance costs: The ultra-long service life and resharpenable design significantly reduce the cost per cut.
We provide customized cutting tool solutions for the critical slitting process in lithium-ion battery manufacturing, ensuring high quality throughout the entire process from raw materials to battery cells.
