Slitting and Shear Knife

Neuenkamp manufactures roll shear knives up to 600 mm (24.00 inches) in diameter for slitting and edge-trimming lines, using our special metallurgies:

    - forged tool steels
    - high speed steels
    - high performance steels
    - special-metals as well as carbides

Knives are available with ground, lapped or polished side faces.

Roll Shear Knives are manufactured to a thickness tolerance of ± 0.001 mm (± 0.000040 inch), and for special requirements knives with a thickness tolerance of ± 0.0005 mm (± 0.000020 inch) can be supplied.

Parallelism and flatness tolerances are within 0.002 mm (0.000080 inch).

These are all prerequisites for the best possible slitting results.

Neuenkamp has been manufacturing high precision longitudinal slitting and side trimming tools for over 80 years. Their main industrial sectors are the steel and non-ferrous metals processors.

Today, Neuenkamp is the world leader in slitting technology, represented in over 30 countries.

Their entire product range of high quality tooling satisfies the entire world market. Special expertise is involved in the manufacturing of the tightest tolerances (accuracies down to ± 0.5µm / ± 0.000020 inch) and the best possible surface finishes. As a standard feature, roll shear knives and spacers have a thickness tolerance of ± 1µm (±0.000040 inch) and parallelism and flatness are within 2 µm (±0.000080 inch). They continuously cooperate with leading steel producers, to develop special knife alloys to obtain the highest wear resistance and prolonged service life.
