Rotary / Counter Knives

Well-known manufacturers of shredder installations and granulators use compact rotor and stator blades.
Hagedorn supplies such tools in various steel qualities, grades of hardness and cutting geometries, depending on the application.
The service includes special grinding procedures tailored to the materials being cut:

  • swing-frame grinding, suitable for standard knives and HSS knives
  • lapping, suitable for all hard metals
  • abrasive belt grinding (micro-finish), provides dust-free cutting and maximum service life
  • hollow grinding (microtome cutting), for cutting high-volume materials
