This is intended to produce the cylinder tubes 290 economically with the lowest possible material cutting. However, this presupposes that the cutting plates 500, which are generally arranged opposite the peeling blades 5, stabilize each other by the balance of the passive cutting forces (a) and (b). [59] Tools for machining thin and wide chips tend to be unstable in general, which can cause chattering during machining. When this phenomenon occurs, the opposing blades can no longer stabilize sufficiently.

Therefore, the cutting plate has a total of 4 of the described main cutting edges 19 and secondary cutting edges 18, 2 of these cutting edges 19/18 diagonally on the first diamond surface and 2 on the second diamond surface lying opposite to the first.
- the fastening receptacles 9 are formed in the embodiment shown as V-grooves 9a. These extend according to the sectional drawings in Figure 5 on both end faces.
- the rake surfaces 19 of the main cutting edges 16 terminate in the region 15 near a respective highest point of one of the main cutting edges 16.
- a rounding 18 at the leading edge provided in addition to the guide region supporting bevel dulls this region so far that machining in this region is precluded.
- a bevel is used instead of the rounding 18.

Fixed fasteners 10 are located on both ends of the peeling knife. A wedge-shaped engagement element 53 is arranged between the cutting plates and engages in their V-shaped grooves 9a. By tightening the clamping screw 54, the cutting plates are clamped against the fastening means 10.
- Two indexable inserts 500 each with 2 cutting edges with inclined clamping faces 55 on both end faces are fastened in tandem arrangement in the peeling knife 32. Fixed fasteners 10 are located on both ends of the peeling knife. A wedge-shaped engagement element 53 is arranged between the cutting plates and engages their oblique clamping surfaces 55.

- a displaceable engagement member 57 is disposed between the cutting plates and engages in their mounting receivers 9 (embodiments according to position 51, 52 or similar).
- the screw receptacle 58 is located with the clamping screw 54. By tightening the clamping screw 54, the inserts are clamped against the sliding engagement member 57 and the fastening means 10.
