Ma'anshan Sheng Ao Heavy Industry Co. Ltd

DESCRIPTION:

Paper Guillotine Knives are precision-engineered cutting blades designed for guillotine paper cutters and industrial paper-cutting machines. They deliver clean, burr-free cuts on various materials, including paper stacks, cardboard, packaging materials, and specialty papers. These blades are critical in industries requiring high accuracy and efficiency, such as printing, bookbinding, packaging, and paper manufacturing. Key Features: High-Quality Materials: Made from high-speed steel (HSS), tungsten carbide, or alloy steel to ensure superior sharpness, wear resistance, and longevity. Precision Engineering: Features a sharp cutting edge (e.g., 21° edge angle) polished to a mirror finish, minimizing friction and ensuring smooth, dust-free cuts. Customization Options: Available in standardized or custom sizes (e.g., lengths from 500mm to 4000mm) with tailored hole configurations, thicknesses, and edge angles to fit specific machinery. Enhanced Durability: Heat-treated and hardened to a Rockwell hardness of HRC 58–68, providing exceptional toughness and resistance to deformation under high-speed operations. Wide Compatibility: Compatible with leading paper-cutting machine brands such as Polar, Wohlenberg, Ideal, Horizon, and Muller Martini. Technical Specifications: Materials: HSS (M2, W18), tungsten carbide, alloy steel (e.g., D2, Cr12MoV). Hardness: HRC 58–68 (varies by material; carbide blades reach HRC 82–84 HRA). Sizes: Common dimensions include 1390×160×13.75mm (Polar 115), 1080×115×11.7mm (Polar 90), and 520×65×10mm (Osaka models). Edge Angles: Typically 19°–23°, optimized for reduced cutting resistance and extended blade life. Applications: These knives are used in: Paper and Packaging: Trimming paper stacks, cardboard, and corrugated materials. Printing and Binding: Precision cutting of books, brochures, and labels. Industrial Processing: Slitting or cutting rolls of paper, films, and composites . Advantages: Efficiency: Mirror-finished edges and sharp angles reduce operational friction and energy consumption. Long Life Span: Hardened materials and reforging capabilities allow repeated regrinding, reducing yearly replacement costs. For example, HSS-inlaid blades can last up to 16 hours of continuous operation. Quality Output: Ensures clean, precise cuts with minimal material waste or fraying. Compatible Machinery Suitable for brands like Polar, Ideal, Wohlenberg, Horizon, and models such as Osaka 2490/368, Polar 115/137, and Perfecta. Custom orders are available for unique machine specifications.
