<p>An arrangement for supplying coolant to rotating cutting tools (1) for metal machining, in particular boring tools provided with coolant ducts (2,3), includes a coolant ring (4) arranged rotatably on the tool shank and sealed with respect thereto and having a radially projecting coupling piece (6) provided with a radial coolant bore. On a carrier piece (10) there are provided two intermediate parts (12) arranged at a distance from one another, each of which is swingable at one end (12a) with respect to the carrier piece (10) about an axis extending parallel to the boring tool axis (A), is slidable in a plane extending perpendicular to the boring tool axis (A) and can be clamped with respect to the carrier piece (10), and each of which has at its other end (12b) a bore (16) extending parallel to the boring tool axis (A) for a fixing bolt (17) which can be screwed into a stationary machine part (S). On the carrier piece (10), a holder (8, 8a) is adjustable parallel to the boring tool axis (A), is rotatable about its axis of adjustment and can be clamped in position. On the holder (8, 8a) there is arranged a radially adjustable coupling head (7) provided with a radially extending outlet bore (23) which, on rotation of the cutting tool, can be coupled automatically with the coupling piece (6) with the interposition of sealing means (21).</p> |
