Mauser-Werkβ Oberndorf OmbH, 7238 Oberndorf Facing head

The invention relates to a facing head with a Facing slide, which can be adjusted transversely using a toothed slide by means of a longitudinal movement of a tension core, for which the tension core is interlocked with the toothed slider is.

In such a known facing head, two tooth slides move during a longitudinal movement of the

Pull core opposite to each other. A backlash-free

Connection between the facing slide and the tension core can hardly be achieved. To the necessary To achieve drive accuracy, tight tolerances must be provided.

The object of the invention is to provide a backlash-free connection between the tension core and the »facing slide to accomplish.

According to the invention, the above object is in a facing head of the type mentioned in the introduction,

that the teeth between the tension core and the Toothed sliders are designed so that a longitudinal movement the pull core both toothed slides in the same way Direction shifts that on the first tooth slide at least an arm is provided which overlaps the second tooth slide laterally, and that the one tooth slide affl facing slide is attached and the other toothed slide against the facing slide in the transverse direction is relocatable and with a the locking screw provided on the arm against the Zugeeele clamped on the facing slide is fixed. This means that the facing slide is connected to the tension core without play · The connection without play can be achieved Adjust slightly on the facing head.

In a preferred embodiment of the invention is the

second toothed slide mounted displaceably against the face slide in the transverse direction. Two of the arms reach over the second tooth slide on the side * However, it is also possible to place the arms on the second tooth slide to be arranged, these then overlapping the first tooth slide laterally.

The one toothed slide is preferably on one side of the tension core and the other toothed slide arranged on the opposite side of the tension core

In an embodiment of the invention, flat guides are between the second toothed slide and the facing slide

stanchions provided «Calibration is not necessary for the arrangement otherwise necessary whale tail guides.

An embodiment of the invention is as follows described. Owned in the drawing
