Metal Circular Slitter Blades

1. What Are They & What Do They Do?

Main Uses

• Cut wide metal coils (steel, stainless steel, aluminum, copper, etc.) into narrow strips

• Provide precise materials for downstream manufacturing (auto parts, home appliances, hardware)

• Boost efficiency in high-volume industrial production

2. Core Features

• Hard & Wear-Resistant: Made of high-quality materials (Cr12MoV, SKD11, etc.) with heat treatment (HRC 58-62). Long service life, less frequent replacement.

• High Precision: Micron-level tolerance control. Clean, burr-free, flat cut edges – no extra processing needed.

• Customizable: Adjust outer diameter, inner diameter, thickness, and cutting angle to fit different slitting machines and materials.

• Stable at High Speed: Minimal deformation, no wobbling. Consistent slitting sizes, less waste.

3. Main Types

• Circular Slitting Blades: Standard, disc-shaped. Most common for regular metal coils (steel, aluminum).

• Irregular Slitting Blades: Custom design (stepped, beveled) for hard-to-cut materials (thick coils, special alloys).

• Upper/Lower Matching Blades: Used together as a pair. Standard for all slitting machines, fits all coil types.

4. Applicable Industries

• Metallurgy: Steel/aluminum mills for large-scale coil slitting

• Metal Processing: Sheet metal companies for custom narrow strips

• Auto & Home Appliances: Precision slitting for parts and casings

• Special Materials: Galvanized, color-coated, copper, and titanium strips

5. Core Processing Technology

• Material Selection: High-toughness alloy steel, high-speed steel, or cemented carbide

• Heat Treatment: Vacuum quenching for uniform hardness and toughness

• CNC Machining: Precise cutting with strict tolerance control

• Custom Cutting Edge: Small angle for thin materials, large angle for thick/hard materials

• Surface Strengthening: Nitriding/TiN coating to reduce wear and material sticking

6. Use & Maintenance Tips

Installation

• Check for chipping/burrs on the cutting edge before installation

• Ensure the blade and spindle are aligned; tighten securely

Parameter Adjustment

• Adjust blade spacing and gap based on material type and thickness

• Too large a gap = burrs; too small = more wear

Operation & Storage

• Clean metal chips during operation to avoid scratching the blade

• Rust-proof idle blades; store in a dry, flat place (no collisions)
