Paper Guillotine Knives

Shengao Precision Paper Guillotine Knives are crafted from premium materials to ensure exceptional cutting performance and durability:

• High-Speed Steel (HSS): M2, W18, and T1 grades for excellent sharpness retention and heat resistance in high-volume paper cutting
• Tungsten Carbide: Superior wear resistance for cutting abrasive materials and extended lifespan
• Alloy Steel: D2, 9CrSi, Cr12MoV for long-lasting sharpness and durability
• Ceramic-Coated: Non-stick surface for cutting adhesive materials and specialized applications

Each material undergoes specialized heat treatment to achieve optimal hardness (HRC 58-64) while maintaining toughness for precision paper cutting applications.

Selecting the appropriate paper guillotine knife depends on several key factors:

1. Material Type: Different paper grades and cardboard materials require specific blade compositions and edge geometries
2. Cutting Thickness: Thicker paper stacks and cardboard require blades with appropriate hardness and edge geometry
3. Production Speed: High-speed applications need blades with specialized steel grades and heat treatment
4. Cut Quality: Fine-cut applications require blades with precision grinding and optimal edge angles (typically 21°-25°)
5. Machine Compatibility: Ensure proper fit for Polar, Wohlenberg, Perfecta, and other guillotine systems

Our technical team provides customized recommendations based on your specific requirements and machine specifications.

Proper maintenance extends blade life and ensures optimal cutting performance:

• Regular Cleaning: Remove paper dust and residue after each use to prevent buildup and maintain cutting precision
• Periodic Sharpening: Maintain cutting edge sharpness using appropriate grinding equipment and techniques
• Proper Storage: Store blades vertically in dry, temperature-controlled environments with protective coatings
• Rotation: Rotate blades in multi-blade systems to ensure even wear and consistent performance
• Lubrication: Apply appropriate lubricants to reduce friction and prevent rust during storage

Shengao offers professional sharpening services and provides detailed maintenance guides with every purchase.
