  • the cutting means is formed by a plurality of cutting elements which are secured to a slip ring, which is releasably secured by a plurality of distributed on the circumference arranged screws on the grinding wheel.
  • both the grinding wheel and the slip ring can be assembled or disassembled not only by complex construction and production, but also with a high handling and time expenditure.
  • This is due to the fact that a plurality of screw holes and screws must be made and assembled or disassembled to secure the slip ring can.
  • the invention has for its object to design a grinding wheel or a slip ring or a wheel body or a closure piece of the types mentioned above so that the adjustment or Umrüs device is easy for different types of material to be ground and with little time and / or Manufacturing and / or assembly work can be done.
