They are key precision cutting tools for metal sheet slitting lines.
Use: Cut wide metal coils (steel, stainless steel, aluminum, copper) into narrow strips of your desired width.
Used in industries like metallurgy, metal processing, auto parts, home appliances, and hardware.
Their precision affects the cut edge’s flatness, burr-free quality, and production speed.
Made of high-quality materials (Cr12MoV, D2, high-speed steel, cemented carbide).
Treated with professional heat (vacuum quenching), hardness HRC58-62.
Optional surface treatment (nitriding, TiN coating) for better wear resistance; fewer blade changes, lower cost.
Cutting edge tolerance is controlled at micron level.
After slitting, edges are flat (no curling, no burrs); no need for secondary processing.
Customize size (outer diameter, inner diameter, thickness) and cutting edge angle.
Supports circular, irregular shapes, and upper/lower blade sets for different needs.
Minimal deformation after heat treatment; no wobbling at high speed.
Ensures consistent narrow strip width; reduces waste, improves material use.
Circular Slitting Knives: Most common, disc-shaped. Adjust multiple blades for different widths; fits ordinary metal coils.
Irregular-Shaped Knives: Custom (stepped, beveled). For thick/hard metal coils and high-precision slitting.
Upper/Lower Matching Knives: Used together for even cutting force; standard for all slitting machines.
Metallurgy: Slit steel/aluminum/stainless steel coils before shipment.
Metal Processing: Secondary slitting for custom narrow coils.
Auto/Home Appliances: Precision slitting for parts, casings, and hardware.
Special Materials: Slit galvanized/color-coated/copper/titanium strips; protect surface quality.
Carbon steel strips (cold/hot rolled): Cr12MoV/SKD-11, HRC58-60; tough and wear-resistant.
Stainless steel (304/316/430): Cr12MoV1/D2, HRC60-62; no chipping, burr-free.
Soft metals (aluminum, copper): High-speed steel (HSS); smooth cut, no material sticking.
Galvanized/color-coated strips: Cr12MoV (mirror-polished/nitrided), HRC58-60; protect coating.
Installation: Check for chipped edges; ensure blade and spindle alignment; tighten securely.
Adjustment: Set blade spacing based on material thickness (too big = burrs; too small = more wear).
Operation/Storage: Clean metal chips timely; rust-proof idle blades; store in dry, flat place; avoid collisions.
