Circular Blade Applications

Shengao circular blades are versatile cutting tools used across numerous industries for processing various materials. Key applications include:

• Slitting Operations: Converting wide rolls of paper, plastic films, non-woven fabrics, rubber, and metal coils into narrower strips with clean, burr-free edges.
• Die-Cutting: Precise cutting and perforation in packaging and industrial product manufacturing.
• Sheet Metal Cutting: Handling thin metal sheets including steel, aluminum, and copper alloys for automotive, construction, and appliance manufacturing.
• Pipe Cutting: Providing clean, precise cuts for plastic, PVC, and thin-walled metal pipes in plumbing and industrial piping applications.
• Food Processing: Meeting strict hygienic standards for slicing food products with materials suitable for food contact.

Our circular blades are engineered for precision to minimize burrs and ensure smooth edges:

• CNC Grinding: Blades are ground to tight tolerances (as precise as ±0.002mm) for exceptional edge sharpness and consistency.
• Tooth Design: Laser-cut Tungsten Carbide Tipped (TCT) teeth are specifically designed to reduce burrs on material edges, particularly important for films and sensitive materials.
• Balanced Design: Reduces vibration during operation, which enhances cutting accuracy and minimizes imperfections.
• Material Selection: Using premium tool steels or carbides that maintain a sharp edge longer, ensuring consistent cut quality throughout the blade's life.

Selecting the right blade material is crucial for performance and longevity. Considerations include:

• Material Being Cut: Abrasive materials may require tungsten carbide for superior wear resistance, while stainless steel is chosen for food processing due to its corrosion resistance.
• Operational Environment: Wet or humid conditions necessitate corrosion-resistant materials like stainless steel.
• Cutting Speed and Hardness: High-speed steel (HSS) handles moderate speeds well, while carbide-tipped blades are better for higher speeds and harder materials.
• Cost-Effectiveness: High-carbon steel offers a balance of durability and cost for general-purpose cutting.

Yes, we offer extensive customization options to ensure compatibility and optimal performance:

• Dimensions: Outer diameter (from 50mm to 500mm or beyond), thickness, and bore size can be tailored to fit specific machinery.
• Material Upgrades: Different grades of tungsten carbide (e.g., YG12X for abrasive materials) or specialized coatings like TiAlN for high-heat environments.
• Edge Configuration: Options include smooth, serrated, or specially beveled edges to suit the cutting task.
• Technical Specifications: We can work with your technical drawings and requirements for expedited solutions.

Tooth geometry is a key determinant of cut quality, speed, and material handling:

• Tooth Count: Higher tooth counts generally produce smoother cuts but may cut slower, while lower tooth counts remove material faster but leave a rougher edge.
• Tooth Shape: Designs like flat-top, alternate top bevel, or triple-chip grind are suited to different materials and cutting styles.
• Tooth Pitch: Fine pitch (teeth close together) is better for thin materials, while coarse pitch (teeth widely spaced) aids in chip evacuation for thicker materials.
• Specialized Designs: For instance, wave blades create decorative edges, and perforation blades create small holes for easy tearing.

Carbide-tipped blades offer several advantages for demanding industrial applications:

• Extended Lifespan: They typically last 3-5 times longer than HSS blades due to the superior wear resistance of carbide.
• Higher Cutting Speeds: Suitable for faster production rates without compromising edge integrity.
• Cleaner Cuts: The hard carbide tips provide sharper edges, resulting in less burr formation and superior cut quality.
• Cost-Effectiveness Over Time: Although the initial cost is higher, reduced downtime for changes and sharpening can lead to lower long-term costs.

Proper care and maintenance are essential for maximizing blade life and performance:

• Regular Cleaning: Remove resin, metal shavings, or dust after use to prevent buildup and corrosion.
• Proper Storage: Store blades in a dry, cool place to prevent moisture damage and avoid contact with other metals.
• Sharpening: Sharpen HSS and carbon steel blades regularly using appropriate techniques; carbide-tipped blades can be reground.
• Inspection: Check blades for cracks, missing teeth, or dullness before use to ensure safety and cut quality.
• Professional Regrinding: Services like Shengao's blade regrinding can extend a blade's lifespan by up to 200%.
