The circular blade of a slitting machine is a core precision component of roll-to-roll slitting equipment, specifically designed for the precise slitting of materials such as paper, film, metal foil, and composite materials. Utilizing high-hardness alloy steel and nano-level precision grinding technology, it ensures stable cutting accuracy, exceptional sharpness, and long-lasting wear resistance even at high speeds, making it widely used in industries such as new energy, packaging, electronics, and printing.

Core Advantages

Ultra-precision cutting edge: Nano-level precision grinding technology ensures a cutting edge sharpness Ra≤0.2μm, guaranteeing a smooth, burr-free cut surface.

Superior wear resistance: Utilizes imported alloy tool steel with a hardness of HRC58-62, improving wear resistance by over 50%.

Excellent dynamic balance: Dynamic balance grade G2.5 ensures stability and low-noise operation during high-speed cutting.

Long lifespan design: Special surface treatment technology extends service life by 2-3 times compared to conventional blades.

Application Areas

New Energy Materials: Lithium-ion battery electrodes, separators, photovoltaic backsheets

Packaging Materials: BOPP, CPP, PET films, aluminum-plastic composite films

Specialty Papers: Capacitor paper, insulating paper, high-grade packaging paper

Electronic Materials: Copper foil, aluminum foil, flexible circuit board substrates
