A feed line 21 for honing oil which opens into the annular groove 17 is attached to the sliding ring 20. The Honing oil supplied via the supply line 21 passes through the annular groove 17 into the channels 16 and from there from the mouths IS into the chambers 4 between the walls or the tubes 1,2. Between Pipes 1, 2 can pass the honing oil through the chambers to the tool end opposite the clamping end 7 22 of the honing bar, the honing oil in the honing bar flowing through the passages 6 communicated over the entire circumference of the honing bar.

At the tool end 22 of the honing bar, a connecting piece 23 is also provided, which is connected to the corresponding Plug-in collars 24, 25 in the inner tube 2, which is set back at its end, and the outer tube 1 is inserted and thereby secured. The between the plug-in collars 24, 25 or one of the inner tube 2 associated shoulder and the outer plug-in collar 25 lying lateral surface 26 of the connection piece 23 is conical. In the area of the connecting piece 23 are on the circumference of the outer tube 1 Evenly distributed over the circumference outlet openings 27 are provided through the ends of channels 28 are formed, which diverge towards the free end of the honing bar. The inner surface lines the outlet channels 28 lie in the conical jacket surface 26 of the connecting piece 23 the end facing away from the walls 1,2 is the connecting piece 23 with a clamping head 29 for a tool provided.

The cross-sections of the outlet channels 28, 27 and the inlet channels 15, 16, as well as the amount of the supplied Honing oils are expediently chosen so that the Rar.m between the walls 1, 2 of the honing rod is always completely filled with honing oil. The five longitudinal chambers 4 protrude, as explained above the passages 6 with one another in line connection. During work, the honing oil flows into the distributor the individual longitudinal chambers and passes through the bores 27 above the head 29 of the connector 23 off again. By arithmetically

ίο certain small passages 6 can the honing oil additionally still flow from one chamber into the other, so that it is particularly advantageous than Vibration damper works.

As the F i g. 1 and 2 also show is in the axis of the honing bar within the inner tube 2 a feed rod 30 is provided, which is mounted in rings 31. which on the inside of the interior Tube 2 are attached. Furthermore, the feed rod 30 is in corresponding holes of the connection

ao pieces 8. 22 stored. With this delivery rod you can the honing stones of the honing tool to be arranged on the honing bar can be adjusted. When shown In the exemplary embodiment, the connecting heads 19, 29 of the honing rod are designed as ball joints.

leads; however, they can also be designed in a different way, for example as bayonet connections being.

Tests with the honing bar according to the invention result in increased material removal, free of chatter marks Surfaces on the workpieces, a low hone noise, as well as an extension of the service life for Diamond, ceramic or bakelite bonded honing stones.
