Zusammenfassung:PCT No. PCT/SU88/00015 Sec. 371 Date Sep. 19, 1989 Sec. 102(e) Date Sep. 19, 1989 PCT Filed Jan. 20, 1988 PCT Pub. No. WO89/06579 PCT Pub. Date Jul. 27, 1989.Disclosure is made of a bar-clamping device having a hollow spindle carrying first and second collets, each provided with a closing drive ensuring independent axial motion of one of the collets relative to the other. The closing drives of each collet are installed in the spindle and designed so that the axial efforts produced during clamping of a bar are directed in the opposite directions.
