<p>The device i.e. hydraulic expansion chuck (1), has a retainer (4) provided at an axial end area of a base body (2). Radial threaded boreholes are distributedly formed along a circumference of the retainer in the base body. The threaded boreholes are screwed into adjusting screws for alignment of a cylindrical shaft (W). The threaded boreholes are formed as passage boreholes. The threaded boreholes are led into an axial inner end area of the retainer such that the adjusting screws indirectly come in contact with the cylindrical shaft.</p> |
