Our company specializes in the production of high-precision slitting and shearing blades, designed for the precise slitting and cutting of various metal sheets (stainless steel, carbon steel, copper, aluminum, etc.). Using top-grade tool steel and mold steel, combined with advanced heat treatment and precision grinding processes, we ensure that our blades possess exceptional sharpness, wear resistance, and dimensional stability, meeting the stringent requirements for cutting edge quality and slitting accuracy in high-end precision slitting production lines.
We utilize high-grade tool steel and cemented carbide to ensure optimal performance matching under various working conditions:
Material/Grade | Main Features: | Recommended Applications: |
|---|---|---|
Cr12MoV / SKD-11 | High hardness, high wear resistance, good toughness | General carbon steel and stainless steel thin and medium plate slitting |
D2 | Extremely high wear resistance and dimensional stability | Continuous high-speed slitting of stainless steel and alloy steel |
H13K | Good high-temperature strength and thermal fatigue resistance | Slitting of silicon steel and high-hardness special steel |
LD | Combination of strength and toughness, impact resistance | Initial cutting and slitting of thick plates and high-strength plates |
W18Cr4V (High-speed steel) | Good red hardness, suitable for high-speed continuous operation | Precision slitting of non-ferrous metals and thin strips |
YG series cemented carbide | Ultra-high hardness, ultimate wear resistance | Slitting of ultra-thin strip materials (such as foils) and abrasive materials |
• Forged Base Material: Utilizing multi-directional forging technology to improve material density and isotropy.
• Heat Treatment System: Vacuum quenching + multiple tempering + deep cryogenic treatment to eliminate internal stress, stabilize the microstructure, and enhance overall performance.
• Precision Machining:
• Ultra-precision grinding: Ensuring straightness and sharpness of the cutting edge.
• Mirror polishing: Surface roughness of the cutting edge can reach below Ra0.1μm, reducing cutting friction and adhesion.
• Dimensional Control: Parallelism ≤0.002mm, thickness tolerance within ±0.001mm.

Q: How to choose between single blades and complete blade sets?
A: Single blades are suitable for flexible production lines with varying product specifications and frequent blade changes. Complete blade sets are suitable for mass production lines with fixed widths, where ultimate efficiency and stability are desired. They avoid adjustment errors during each installation through pre-set precision.
Q: What is the recommended sharpening cycle and number of times for the blades?
A: This depends on the type, thickness, and production volume of the slitting material. Sharpening is usually required after a certain tonnage of material has been processed or when the cutting edge quality deteriorates. High-quality blades can be sharpened 10-15 times or more.
Q: Can you solve the burr problem during slitting?
A: Yes. Burrs are usually related to blade sharpness, gap setting, and equipment condition. We will first inspect your equipment and provide targeted blade edge optimization solutions and process parameter adjustment suggestions.
