Slitting Knives and Slitting Spacers

🔧 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.
