ABSTRACT:
A centerless turning machine for rods. The machine includes a cutter-head mounted at the front end of a rotating hollow shaft, and further includes a plurality of advancing rollers of an infeed device operatively mounted at the inlet end of the turning machine. The turning machine further includes a front guide mechanism and a rear guide mechanism, respectively mounted on opposite sides of the cutter head, and also includes a clamping carriage which is mounted on the outlet side of the turning machine. The rear guide mechanism takes the form of a tubular support which is provided with a flange mounted in the machine housing and which extends into the rotating hollow shaft. The rear guide mechanism has, at its free end, which protrudes into the hollow shaft, three individually spring biased guide elements for the rod. The springs for each individual guide element form a first resilient abutment for each guide element. The movements of the three guide elements are synchronized by a rotatable ring. The rotational position of the ring is prestressed against the housing. Upon a closing movement of the adjustmeent ring, the individual springs are compressed and finally each guide element abuts against a second rigid abutment.
