Es ist bekannt, daß die erste Lagerstelle für die Lünette an langen Wellen o. dgl. nach dem bisherigen Arbeitsverfahren niemals genau rund wird; man versuchte dieses Übel dadurch zu beseitigen, daß diese Lagerstelle mit der Feile nachgearbeitet wurde. Trotzdem zeigten sich dann an der fertiggedrehten Welle beträchtliche Toleranzen, die beim Zusammenbau äußerst störend wirkten. Es sind to bereits Lünetten mit eingebautem Schneidwerkzeug bekannt, die lediglich zur allgemeinen Bearbeitung dienen und bei denen das Schneidwerkzeug ständig neben der Lagerstelle des Werkstückes in der Lünette arbeitet, nicht aber zum Egalisieren dieser Lagerstelle verwendet wird.It is known that the first bearing point for the steady rest on long shafts o the previous working process never gets exactly round; one tried this evil to be eliminated by reworking this bearing point with the file. Nevertheless Then there were considerable tolerances on the finished shaft, which during assembly were extremely disturbing. There are already known steady rests with built-in cutting tools, which are only used for general purposes Machining are used and in which the cutting tool is constantly next to the bearing point of the workpiece in the steady rest works, but not to equalize this bearing point is used. Um nun genau runde Lagerstellen an langen Wellen o. dgl. für die Lünette zu erzielen, besteht die Erfindung darin, daß das Schneidwerkzeug in der Spannvorrichtung der Lünette in der Ebene der Druckstücke der Lünette liegt und mindestens die Breite einer Druckfläche hat.In order to achieve exactly round bearings on long shafts or the like for the bezel, The invention is that the cutting tool in the jig of the Steady rest in the plane of the pressure pieces of the steady rest and at least the width of a Has printing area. Hierdurch werden genau runde Lagerstellen für die Lünette und dadurch auch genau runde Wellen erzielt, so daß nicht nur viel Zeit, Mühe und unnötige Arbeit, sondern auch viel Kosten erspart werden. jThis results in exactly round bearings for the steady rest and thereby also achieved exactly round waves, so that not only a lot of time, effort and unnecessary work, but also a lot of costs can be saved. j Die Zeichnung zeigt in bekannter Weise j eine Lünette α mit den Spannbacken b. Auf I dieser Lünette α sitzt eine Vorrichtung c, in der ein Stahl d befestigt ist. Die Vorrichtung c kann von beliebiger Form sein und läßt sich auf jeder Lünette anbringen.The drawing shows in a known manner a steady rest α with the clamping jaws b. On I of this bezel α sits a device c in which a steel d is attached. The device c can be of any shape and can be attached to any bezel. Soll nun eine vorgedrehte, für die Lünette bestimmte Lagerstelle genau rund werden, so wird die mit der Vorrichtung c versehene Lünette α in bekannter Weise um die vorgedrehte Lagerstelle gelegt. Ein in die Vor-. richtung r. gespannter Stahl d, der aber mindestens die Breite der vorgedrehten Lagerstelle hat, beseitigt beim Drehen die auf der Lagerstelle vorhandenen Unebenheiten dadurch, daß die dem Stahl gegenüberliegende Spannbacke diese Unebenheiten gegen den Stahl drückt und so eine genau rund werdende Lagerstelle erzeugt wird; danach erfolgt weitere Fertigbearbeitung der geschmiedeten, gewalzten oder gezogenen Welle o. dgl. in bekannter Weise.If a pre-rotated bearing point intended for the steady rest is now to be precisely round, the bezel α provided with the device c is placed around the pre-rotated bearing point in a known manner. One in the fore. direction r. tensioned steel d, which has at least the width of the pre-turned bearing point, removes the unevenness present on the bearing point when turning, in that the clamping jaw opposite the steel presses these unevenness against the steel and thus a precisely round bearing point is created; this is followed by further finishing of the forged, rolled or drawn shaft or the like in a known manner. Patkn'i'ansi'kucii :Patkn'i'ansi'kucii: Lünette mit eingebautem Schneidwerkzeug zum genauen Runddrehen der Lagerstelle für Lünetten, dadurch gekennzeichnet, daß das Schneidwerkzeug (d) in der Ebene der Druckstücke (b) der Lünette liegt und mindestens eine Breite der Druckfläche hat.Steady rest with built-in cutting tool for precise turning of the bearing point for steady rests, characterized in that the cutting tool (d) lies in the plane of the pressure pieces (b) of the steady rest and has at least the width of the pressure surface.
