Circular blades can be categorized into multiple types based on edge structure, shape, and application. Different blade types correspond to different cutting materials and operating conditions, directly impacting cutting effectiveness, precision, and service life.
1. Smooth Edge Circular Blade (Plain Edge)
Features a straight, smooth circular cutting edge. It is the most versatile model.
• Applications: Slicing, trimming, and edge-finishing of soft/thin materials such as films, paper, non-woven fabrics, aluminum foil, and adhesive tapes.
• Characteristics: Produces clean, burr-free cuts with high precision. Suitable for high-speed slitting.
2. Serrated Edge Circular Blade (Toothed Blade)
Features a serrated edge with uniform teeth, available in fine-tooth and coarse-tooth types.
• Applications: Cutting of thicker or more resilient materials like cardboard, paperboard, carpets, leather, and thick non-woven fabrics.
• Characteristics: Provides strong cutting force with minimal slipping. Ideal for rough cutting and intermittent cutting operations.
3. Wavy Edge Circular Blade
Features a wavy, curved cutting edge.
• Applications: Cutting of easily deformable materials like non-woven fabrics, hygiene products, foam, and knitted fabrics.
• Characteristics: Offers low cutting resistance, prevents material sticking, and ensures stable, aesthetically pleasing cuts.
4. Top & Bottom Slitting Circular Blades (Dish/Trapezoidal Blades)
Typically used in matched pairs, featuring angled cutting edges.
• Applications: High-speed slitting of web materials like plastic films, roll paper, non-woven fabrics, and adhesive tapes.
• Characteristics: Paired usage extends service life, increases slitting efficiency, and is suitable for large-scale slitting machines.
5. Notching/Arcuate Circular Blades
Features cutting edges with specific curvatures or grooves.
• Applications: Notching, creasing, and special-shaped cutting of materials like leather, PVC, and paperboard.
• Characteristics: Meets non-standard processing requirements, allows for one-step forming, and enhances processing efficiency.
6. Food-Grade Circular Blades
Made from food-grade materials, featuring a smooth, easy-to-clean cutting edge.
