Technical Specifications

Material Advantage: Why Cr12MoV?

Cr12MoV is one of the most reliable cold-work alloy tool steels for industrial slitting blade manufacturing.

For this 390mm Outer Diameter Cr12MoV Large Bevel Flat Blade, it provides:

• Excellent wear resistance for long production cycles

• High compressive strength under heavy cutting loads

• Strong anti-chipping performance

• Superior edge retention after repeated operation

• Good dimensional stability after heat treatment

Compared with standard carbon steel blades, service life is typically extended by 2–3 times under identical operating conditions.

Key Features and Technical Advantages

1. Optimized Large Bevel Cutting Edge

The large bevel angle significantly reduces cutting resistance, allowing smoother material entry and minimizing deformation. This design is particularly effective for thick rubber sheets, conveyor belts, and other high-toughness materials, ensuring clean, burr-free edges without sticking or tearing.

2. Precision Flat Blade Structure

The flat blade body ensures superior flatness and concentricity, which directly impacts slitting accuracy. Stable installation and balanced rotation eliminate vibration and deviation, maintaining consistent strip width during high-speed operation.

3. Industrial Compatibility

With a standard outer diameter of 390mm, this blade is compatible with most slitting machines and strip-cutting equipment. It can be integrated into complete tooling systems with spacers and holders, making it a reliable option for OEM and replacement markets.

Typical Applications

· Rubber conveyor belt slitting and strip cutting

· Industrial belt and canvas processing

· PVC, PU, silicone sheet and film slitting

· Leather, textile, and paper roll cutting

· Flexible material continuous slitting lines

Frequently Asked Questions

Q1: What materials can this blade cut?

The 390mm Outer Diameter Cr12MoV Large Bevel Flat Blade performs best on flexible and semi-flexible materials such as rubber, conveyor belts, leather, plastic films, paper rolls, and industrial textiles.

Q2: How long is service life?

Under standard conveyor belt slitting conditions, service life is typically 2–3 times longer than ordinary alloy steel blades, depending on cutting speed and material hardness.

Q3: Can it be re-sharpened?

Yes. The Cr12MoV substrate supports multiple precision regrinding cycles without affecting structural stability.

Q4: Can you manufacture according to our machine drawing?

Yes. Xinzhe Blades provides full drawing-based customization for industrial blade procurement projects.
