How The Circular Flat Knife Was Produced？

1.1 Precision Manufacturing, Material-Based
Our circular flat knive utilize a diverse material system to meet the needs of diverse working conditions:

440C stainless steel: Contains 1.2% carbon and 16-18% chromium. After cryogenic treatment, it reaches a hardness of HRC59-61. It offers both corrosion resistance and toughness, making it suitable for high-precision applications such as food packaging and aluminum foil slitting.

ASP23 high-speed steel: Contains 8% cobalt, achieves a hardness of 64-66 HRC as quenched and stabilizes at 58-60 HRC after tempering. It offers excellent high-temperature strength and is suitable for difficult-to-cut materials such as stainless steel and titanium alloys.

HSS high-speed steel: An economical choice for cutting carbon steel and aluminum, offering an outstanding cost-effectiveness.

1.2 Specifications and Technological Innovations
Diameter Range: ∮300-1000mm, Thickness: 0.5-300mm. We offer a wide range of options, including flat circular knives, serrated circular knives, and alloy circular knives. Slitting Process: Supports tangential/non-tangential shearing and extrusion slitting, achieving micron-level precision, low cutting resistance, and high wear resistance.
Waste Removal Technology:
Ejector-Type Waste Removal: Minimum processing aperture 0.6mm, silent, suitable for small-aperture waste removal.
Air Blowing Waste Removal: Effectively removes waste from regular apertures 3-10mm. Combined with an air guide ring and waste removal box, it offers high cleaning efficiency.

2.1 Standardized Customization Process
Requirement Confirmation: Customers submit parameters such as blade type, material, and dimensions, and engineers coordinate the details.
Design Verification: Generate CAD drawings to confirm material machinability and heat treatment solutions.
Production and Processing:
Forging and Heat Treatment: Optimize carbide distribution and enhance hardness and toughness through annealing, quenching (in brine/oil-based media), and tempering (low-temperature controlled).
Precision Grinding: Use an optical curve grinder to process complex blade shapes, ensuring precise geometric parameters. Quality Inspection and Packaging: Full-process dimensional and hardness testing, five-layer corrugated cardboard reinforcement, foam/sponge filling, plastic blade protection, and rust-proofing.
2.2 Customization Scope and Case Studies
Non-Standard Support: Custom diameters, thicknesses, and waste discharge structures (such as a dual-fluid burner blade pattern) can be customized.
Typical Case Studies:
Aluminum Foil Slitting: Customized ∮800mm alloy circular blades for a company, achieving a slitting accuracy of ±0.05mm and extending service life by 30%.
Rubber Extrusion: Providing ejector-type waste discharge circular blades, increasing waste handling efficiency by 50% and reducing downtime.
