    Rotary Slitter Knives

    We manufacture rotary slitter knives for all common machine types:

    Advantages of the TKM Rotary slitter knife:

    • Adherence to the smallest possible thickness tolerance down to ± 0.0005 mm
    • Subdivision of thickness tolerance in
      3 areas (-, 0, +)
    • 4 highly precise surface finishes
    • Suitable for sheet metal thicknesses from 0.006 to approximately 16 mm and in exceptional cases also to 40 mm
    • Rotary slitter knives ground with a single-sided facet and an exact edge

    Surface finishes & Cutting edge quality


    Surface finishes Cutting edge quality
    We manufacture rotary slitter knives with four surface finishes, depending on the cutting application. Our aim is the continual optimization of the cutting edges with respect to their execution and quality (break-out- and burr-free).
    Surface finishes Optimized Cutting Edges

     

    Surface Gloss Level (GU(20°))
    Surface finish roughness Ra (µm)
    Ground ≈ 50-200 ≤ 0,40
    Lapped ≈ 0-5 ≤ 0,20
    KSF-microplan ≈ 50-200 ≤ 0,10
    Mirror polished ≈ 600-1.100 ≤ 0,03

    Rotary Slitter Knives

    We are constantly working on the development of new knife materials in order to perfect the wear resistance and toughness for specific tasks.
    This pride in discovery ensures an optimal balance between the determination of the knife material and the tuned heat treatmentprocesses.
    As a result we produce the right "recipe" for your cutting application.


    We produce rotary slitter knives in four different tolerance classes to meet the requirements of our customers.
