PCT No. PCT/SE86/00385 Sec. 371 Date May 1, 1987 Sec. 102(e) Date May 1, 1987 PCT Filed Aug. 29, 1986 PCT Pub. No. WO87/01320 PCT Pub. Date Mar. 12, 1987.A self-centering steady rest with extensive diameter clamping range for centering cylindrical workpieces on machine tools using a constant linear displacement clamping force. The steady rest includes two pivoting levers arranged symmetrically about a linearly displaceable slide with the levers being swingable from their starting position, i.e. the maximum open position of the steady rest, in which the levers have a V-shaped configuration, to a final position in which the levers are substantially parallel to each other. The steady rest is of compact construction reducing the amount of space required for the steady rest in a machine tool. |
