Main Features
- Precision Multi‑Groove Profile: Integral multi‑edge grooved structure completes multiple cutting tracks in one rotation, matching upper slitter knives for synchronous multi‑strip separation.
- Strict Dimensional Tolerance: Ultra‑tight parallelism and runout control prevent offset cutting during high‑speed equipment operation.
- Premium Tool Steel Substrate: High‑alloy tool steel raw material supports long‑duration heavy‑load slitting work conditions.
- Optional Cryogenic Treatment: Optimizes internal material microstructure to strengthen edge stability and anti‑abrasion performance.
- Precision Bore Machining: High‑accuracy inner bore ensures concentric installation on slitter arbor, reducing runtime vibration.
Advantages
- Consistent Multi‑strip Cutting Effect: Uniform groove precision generates neat cutting sections with low burr rate, lowers finished‑product rejection rate.
- High Production Efficiency: Realizes multiple strands cutting in single pass, reduces tool replacement frequency and improves line throughput.
- Excellent Wear Resistance: Heat‑treated tool steel extends service life, cuts down downtime caused by blade maintenance.
- Stable High‑speed Operation: Fine‑tuned concentricity suppresses vibration, adapts to long‑time continuous running of slitting equipment.
- Flexible Custom Support: Groove number, groove pitch, outer‑inner diameter and hardness can be adjusted according to actual slitting requirements.
Product Applications
- Metal processing: Slitting for aluminum foil, copper foil, thin stainless‑steel coil strips.
- Paper & packaging industry: Paper roll, composite paper, adhesive base‑paper multi‑strip dividing.
- Film & new‑material industry: Plastic film, laminated composite material multi‑track slitting.
- Equipment matching: Serves as bottom mating knife for various rotary slitting machines.
