Frequently asked questions

Common questions

Do you make circular knives to size or to drawing?

Yes. We manufacture every circular knife to drawing or from a sample, with the outer diameter, inner diameter, thickness and edge type your longitudinal slitting line requires.

What materials and hardnesses do you work with?

We work with tool steel, HSS and tungsten carbide. We choose the material according to what you will cut and your production volume, seeking the best balance between edge quality and service life.

What tolerances do you manufacture to?

High-precision tolerances —down to the micron— in thickness, flatness and concentricity, to guarantee clean, consistent cuts even in continuous production.

Do you offer circular knife regrinding?

Yes. We regrind and recondition circular knives to restore their cutting geometry and extend their service life, reducing your operating costs.
