🔧 1. Slitting Knives
Slitting knives are the core cutting components used in slitting lines. They are designed to longitudinally slit wide steel coils into narrower strips. Suitable for a wide range of materials including stainless steel, carbon steel, galvanized steel, silicon steel, and aluminum.
Features:
-
Premium Materials: Commonly used materials include alloy tool steel and powder metallurgy high-speed steel (e.g., D2, SKD11, H13, Cr12MoV, ASP2053).
-
High Hardness: HRC 58–65 for excellent wear resistance and long service life.
-
Sharp Edges: Ensure clean cuts with minimal burrs.
-
Precise Heat Treatment: Delivers superior heat resistance and fracture toughness.
🧩 2. Slitting Spacers
Slitting spacers are placed between slitting knives to maintain consistent knife spacing and ensure precise slitting. They are essential for knife gap adjustment, positioning, and cushioning.
Features:
-
High Dimensional Accuracy: Tolerance up to ±0.001 mm.
-
Durable Materials: Typically made from high-hardness tool steel or stainless steel.
-
Surface Finishing: Includes black oxide, chrome plating, or nickel plating.
-
Various Types Available: Includes rubber spacers, metal shims, and solid precision spacers.

🛠 Maintenance Guidelines
🔪 Slitting Knives
-
Regular Sharpness Check: Regrind when burrs appear or cutting quality declines.
-
Use Proper Cleaning Agents: Avoid metal debris buildup on the blade edge.
-
Storage: Keep knives separated using dedicated racks or boxes to avoid chipping.
-
Regrinding Schedule: Typically every 8–12 hours of cutting, depending on material hardness.
-
Avoid Overheating: Control cutting pressure and speed to prevent annealing or deformation.
🧩 Slitting Spacers
-
Avoid Scratches and Damage: Ensure spacer surfaces remain smooth for precise positioning.
-
Rust Prevention: Apply anti-rust oil regularly and clean before use.
-
Dimensional Calibration: Verify thickness when adjusting for different material gauges.
-
Labeled Storage: Store different thicknesses separately and clearly marked to prevent mix-up.
