- the removal unit 8 is in a first operating position, in which the ends of the disk bearing axes 15 are in the radial direction in the region of the rear side in the direction of rotation of the adjusting plate 42 after rotating the adjusting plate 42 in the first direction of rotation further outward ends of the Zwangs exchangesausappelisme 43 are arranged.
- the impact disks 9, as in the embodiment of the removal unit 8 according to FIG. 2 are raised relative to the cutting edges 28 of the cutting inserts 11 without the action of external forces in the radial direction.
- FIG. 22 shows in a perspective view the further embodiment of a removal unit 8 according to FIG. 21 in a second operating position, which has been adjusted starting from the first operating position according to FIG. 21 in that the adjustment plate 42 is oriented in the direction of that indicated in FIG Arrow has been rotated in a direction opposite to the first rotational direction of the second rotational direction until the ends of the disc bearing axles 15 in the region of the radially inwardly located forward ends of the Zwangs Adjustsausappel 43 are arranged.
- the impact disks 9 relative to the arrangement in the first operating position shown in Fig.
- FIG. 23 shows a side view of a further embodiment of a removal unit 8 for a device according to the invention, wherein in the further embodiment of a removal unit 8 according to FIG.
- the removal unit 8 in the embodiment according to FIG. 23 has cutting bases 10 'acting in two directions of rotation and therefore acting on both sides, which has two circumferentially arranged groups of first cutting plates 11a and second cutting plates 11b each having a cutting edge 28. Each group of first cutting plates 1 1 a and second inserts 1 1 b is preceded by a Abstreifmodul 12.
- Each double-sided cutting base 10 ' is tilted in the circumferential direction with its base body 22 via a tilting axis 45, which crosses the base body 22 in one of its outer side 24 opposite foot, and otherwise secured in the axial direction of the Abtragsaku 8 substantially free of play.
- Each base body 22 of a double-sided cutting base 10 ' is formed on the side facing away from its outer side 24 of the tilting axis 45 with a stop pin 46 which extends in the radial direction inwardly in the direction of the output shaft 6.
- rotatable adjusting sleeves 47 are arranged in the circumferential direction, which have a number of stop ribs 48.
- the abutment ribs 48 extend radially away from the output shaft 6 in a star shape, so that in each case a pin receiving space 49 is formed between pairs of stop ribs 48 adjacent in the circumferential direction.
- Each pin receiving space 49 receives a stop pin 46 of a socket body 22 of a double-sided cutting socket 10 'and is in Um- Starting direction greater than the respective stop pin 46 dimensioned.
- the adjusting sleeves 47 are rotated such that the walls of the stop pins 46 located at the front in the clockwise direction abut against the abutment ribs 48 lying opposite them, so that the cutting edges 28 of the first cutting inserts 1 1 a in FIG radial direction relative to the cutting edges 28 of the clockwise lying on the front side second inserts 1 1 b are raised.
- the Abtragsaku 8 counterclockwise in the radial direction in the clockwise front raised cutting edges 28 of the first cutting 1 1 a with a material 32 engage, while in this direction, the cutting edges 28 of the other group of front-side second cutting inserts. 1 1 b are free of intervention.
- FIG. 24 shows in a side view the further embodiment of a removal unit 8 according to FIG. 23 in a second operating position, in which the adjustment sleeves 47 have been rotated clockwise so far in relation to the first operating position according to FIG. 23 that the walls lying at the rear in the clockwise direction abut the stopper pin 46 on the opposite stop ribs 48.
- the cutting edges 28 of the second cutting inserts 1 1 b lying in the clockwise direction are now raised in the radial direction in relation to the cutting edges 28 of the first cutting inserts 1 1 a located at the rear in the clockwise direction.
