PCT No. PCT/EP90/01300 Sec. 371 Date Feb. 19, 1992 Sec. 102(e) Date Feb. 19, 1992 PCT Filed Aug. 8, 1990 PCT Pub. No. WO91/02612 PCT Pub. Date Mar. 7, 1991.The feeding apparatus has a holding plate (15) which is provided with passage bores (18) for the accommodation and mounting of the rear end of the guide tubes (12) of the turning machine. The holding plate (15) is mounted on a supporting frame (16) for rotation about the central axis of the spindle drum of the turning machine. On the side of the holding plate (15) facing away from the spindle drum there is a cover plate (26) which is coupled non-rotatably to the supporting frame (16) and which is sealed against the holding plate (15). Between the holding plate (15) and the cover plate (26) is a distribution passage (38) with which on the one hand the openings of the guide tubes (12) are in communication and to which on the other hand a damping fluid feed line is connected. Advantageously, a passage bore (42) is present in the cover plate (26) in the alignment of one of the guide tubes (12), and can be closed by a closure (43) whose passage width is at least approximately equal to the largest diameter of the workpieces.
