Dies zusätzlich bei 8 unterteilt bzw. geriffelt, wobei die ist umständlich sowie die Einstellung ungenau und Spannhülse für außenseitig dichten Abschluß sorgt, die Halterung nicht immer einwandfrei. 45 Das Druckmedium (Öldruck) gelangt über diehave fractures distributed over the circumference, which is with, the expansion shaft consists of the hollow shaft I ₁ corresponding pads are closed, which is closed at both ends at 2 and 3 and in radial bores 5, sowk, running from the inside against the attached tools or outer grooves 4 Guides are pressed to their tension. 40 has an enclosing clamping sleeve 6. The outer grooves 4 on the hollow shaft 1 for adjusting the tools and brackets are to be loosened by means of transverse grooves, the retaining cushions are to be loosened and the parts to be designed in a grid-like manner and the locking fields to be pushed and then re-tightened. This is also subdivided or corrugated at 8, which is cumbersome and the setting is imprecise and the clamping sleeve ensures a tight seal on the outside, the bracket is not always perfect. 45 The pressure medium (oil pressure) reaches the
