Description
Precision Roll to Roll Slitting Machine for Lithium Battery Electrodes | ±0.03mm Accuracy
Product Overview
Our Roll to Roll Slitting Machine is a high-precision bench-top slitter designed for the continuous slitting of lithium battery electrodes, metal foils, optical films, and other functional roll materials.
Featuring an ultra-fine tungsten steel blade system and independent upper/lower circular knife design, it delivers burr-free, wave-free slitting with an accuracy of ±0.03mm. Ideal for R&D labs, pilot lines, and small-batch production where material quality is critical.
The machine is PLC-controlled with an HMI touchscreen for easy operation, and features independent tension control on upper and lower rewinding shafts for optimal material handling.

How It Works
- Unwinding: The roll material is mounted on the unwinding shaft with automatic tension control to maintain constant tension throughout the process.
- Slitting: Material passes through the upper and lower circular knife assembly. Blade cutting depth is precisely adjustable via micrometer (0.2~0.4mm). The ratio of knife speed to material linear speed is adjustable to suit different materials and thicknesses.
- Dust Removal: An integrated dust removal device continuously removes particles generated during slitting, keeping the material clean.
- Rewinding: The slit strips are independently rewound on upper and lower shafts. Each shaft’s tension can be independently adjusted within 0-50N, ensuring neat rewinding without wrinkles.
- Control: All parameters (speed, tension, length count) are set via the HMI touchscreen, with the PLC automatically executing the process.
Equipment Features
- Precision Knife Seat Design: Independent knife seat structure ensures long-term stability and achieves extremely high-precision foil slitting.
- Ultra-Fine Tungsten Steel Blades: Excellent slitting quality with smooth, burr-free edges. Ultra-long service life reduces replacement frequency.
- Defect-Free Finished Product: No burrs, no wave edges, no indentations – meeting high-quality battery production standards.
- Adjustable Cutting Depth: Blade penetration can be finely adjusted with micrometer display, adapting to different material thicknesses.
- Angle Adaptability: By adjusting the feeding and discharging angles, the machine can accommodate materials of different compositions and thicknesses.
- Single Vertical Plate Structure: Compact structure with excellent rigidity, easy to clean and maintain.
- Dust Removal Device: Standard equipment to keep materials and workspace clean.
- Independent Tension Control: Upper and lower rewinding shafts have independently adjustable tension (0-50N) to suit different material rewinding characteristics.

Frequently Asked Questions (FAQ)
Q: What material thicknesses can this machine handle?
A: The standard cutting thickness range is 100~300μm. For thinner or thicker materials, please contact us for customization options.
Q: How do I adjust the slitting width?
A: Width adjustment is achieved by changing the spacers on the knife shafts. The standard adjustment range is 20~280mm, and custom ranges are available upon request.
Q: Will there be burrs after slitting?
A: No. Our machine uses ultra-fine tungsten steel blades and a precision knife seat design, controlling burrs to ≤25μm – meeting strict lithium battery electrode standards.
Q: Can I adjust the rewinding tension?
A: Yes. The upper and lower rewinding shafts have independently adjustable tension from 0-50N, allowing you to optimize for different materials and prevent wrinkling or stretching.
Q: Does the machine require special installation?
A: It’s a bench-top unit with a compact footprint (850×800×700mm). Simply place it on a stable workbench in a clean environment (25±3℃, 30-90% humidity, no vibration).
Q: Do you provide spare blades?
A: Yes, we offer spare blade sets. While our tungsten steel blades have an exceptionally long life, we recommend keeping a spare set for continuous production.
Q: What’s the delivery time?
A: Please contact our sales team for current lead times based on your configuration and destination.
