Technical Specifications

Parameter

Description

Material Options D2 (SKD11), HSS (M2), LD, A8, High-Grade Carbide (Customizable)
Hardness (HRC) $58-62$ HRC (Optimized for shearing tough materials)
Tolerances Flatness (Parallelism) $\le 0.003mm$; Runout $\le 0.005mm$
Outer Diameter (OD) Range: $50mm$ to $500mm+$ (Fully Customizable)
Inner Diameter (ID) Precision bore size for secure fit on arbors (e.g., $100mm$)

Main Features

  • Ultra-High Precision: Manufactured to achieve ultra-high flatness slitting tools and parallelism, eliminating common slitting issues like double burr or frayed edges.

  • Superior Material Grade: The utilization of high-chrome tool steels (like D2) ensures a hard, resilient edge required for continuous metal coil rotary shear blades operations.

  • Optimized Wear Life: Optional deep cryogenic treatment enhances the molecular structure, significantly extending the life of the D2 steel rotary slitter replacement.

  • Complex Grooving: Capable of producing intricate custom multi-groove circular knives profiles (as pictured) for specialized multi-cut or sizing applications.

  • Dynamic Balance: All large rotary knives are dynamically balanced for vibration-free, high-speed operation.

Advantages

  • Flawless Edge Quality: Guaranteed minimal burr and clean, straight edges on the slit material, reducing waste and improving product marketability.

  • Extended Running Time: Exceptional wear resistance means less frequent stopping for tool changes, maximizing production uptime.

  • Perfect Fitment: Precise ID and keyway machining ensure perfect alignment and stability on the slitter arbor.

  • Custom Sizing: Experts in providing custom OD/ID rotary cutting tools and non-standard thickness to match any slitting line configuration.

  • Cost-Effective OEM Alternative: Offering premium quality at manufacturer-direct pricing, providing a cost-effective alternative to OEM parts.

Product Specifications

  • Metal Slitting: For carbon steel, stainless steel, aluminum, copper, and specialized metal foils.

  • Film/Paper Slitting: High performance film slitter knives for plastic film, adhesive tape, and thermal paper.

  • Bottom Slitters: Used as the bottom knife or spacer in a set (tool steel bottom circular cutter).

  • Top Slitters: Used as the upper cutting knife.

  • Spacer Rings: Available in steel or rubber to complete the entire slitting set.

  • Custom Service: We require detailed blueprints, including all dimensional tolerances (OD, ID, thickness, runout, parallelism).

Why Choose Us

  • Specialization in Slitting: Deep expertise solely focused on the intricate demands of high-tolerance rotary slitting and shearing tools.

  • Cryogenic Treatment: Advanced optional service to enhance wear resistance far beyond conventional heat treatment.

  • Tolerance Guarantee: Our QA process guarantees the demanding flatness ($\le 0.003mm$) required for clean metal slitting.

  • Full Slitting Set Supplier: We provide not just the knife, but the full custom multi-groove circular knives setup, including spacers and wear rings.
