  • Fig. 1 discloses on embodiment of the ring cutter according to the present invention and Fig. 2 discloses a further embodiment of the ring cutter according to the invent ⁇ ion, whereby Fig. 2 discloses that the ring cutter is devided, namely in two half circle shaped parts . According to the invention, the ring cutter 1 also can be devided into more than two parts .
  • the root portion 2 of the ring cutter 1 comprises a downfall shape, corresponding with a groove 3 in the rotation body 3 of the ring cutter.
  • the groove 3 is constituted by the rotation body itself in one side and in the other side of a nut 4 which by means threads is threaded on to the rotation body 5.
  • the groove 3 will be widend so much that the two segments of the ring cutter 1 can be removed radially and new ring cutter segments can be inserted, whereafter the nut 4 is threaded and tightend in a suitable way to secure the ring cutter 1 in the groove 3 by locking the root portion 2 of the ring cutter 1 in the groove 3.
  • Fig. 2 discloses a cross section of another embodiment for securing the two segments of the ring cutter.
  • the two segments of the ring cutter are together not a complete circle, but wedges 6 -are inserted diametrically to each other between the two segments , whereby the extreme phases of the segments are provided with inclined surfaces corresponding to the inclined surfaces of the wedge 6.
  • the wedge 6 is tight- end with bolts 7 to the rotation body 5 to ensure that the ring cutter segments are secured to the rotation body.
  • Guidings 8 are secured to the rotation body 5 on each side of the ring cutter 1 for axial guding of the ring cutter segments.
  • a centric guide 9 is secured to the rotation body 5.
