20. Moving bezel (optional)
Bezels counteract the bending of longer shafts that is caused by shaving forces. The roll jaws
prevent the bending of the turning elements.
They are to be set in such a way that the rotating axis of the work piece is precisely flush with the
rotating axis of the machine. At eth support position, the turning parts must be accurately rounded.
20.1 Operating the moving bezel
1. The moving bezel is used, primarily, when turning thin, long shafts and when turning longer
threaded spindles.
2. The bezel (1) is screwed to the intended threaded holes in the tool skid using the two fixture
screws (2).
3. The roll jaws should be as close to the tool cutting edge of the turning chisel as possible to ensure
that the work piece cannot bend.
4. The slider (3) can be moved by opening the clamping screws (4), afterwards the clamping screws
(4) must be tightened up again.
