Description
Beim Gewindeschneiden auf der Drehbank nimmt der Dreher bekanntlich, um die Arbeit zu beschleunigen, zuerst stärkere, dann immer schwächer werdende Späne.As is well known, when thread cutting on the lathe, the lathe operator takes to the work to accelerate, first stronger, then weaker and weaker chips.
Die vorliegende Erfindung betrifft eine weitere Ausbildung des Gegenstandes des Patents 416989, wodurch mit einem Gewindeschneidzeug ebenfalls zunächst starke, dann schwächere Späne geschnitten werden. Durch die zuletzt arbeitenden Gewindeschneidzähne wird also das Schlichten der vorher grob eingeschnittenen Gewindegänge besorgt.The present invention relates to a further embodiment of the subject matter of the patent 416989, whereby with a thread cutting tool also initially strong, then weaker chips are cut. Through the last working thread cutting teeth So the finishing of the previously roughly cut threads is taken care of.
Diese Wirkung wird dadurch erreicht, daß bei dem Schneidzeug nach dem obigen Patent die Mittenentfernungen der Schneidzähne vom Ende des Schneidzeuges nach dem Anschnitt hin zunehmen. Die .Hauptspanabnahme erfolgt durch die eine Gewindeflanke, während die andere stets einen gleichmäßig dünnen Span abnimmt, damit die an dieser Flanke anlie-This effect is achieved in that in the cutting tool according to the above patent the center-to-center distances of the cutting teeth from the end of the cutting tool after the first cut to increase. The .Main chip removal takes place through one thread flank, while the others always take an evenly thin chip so that the
gende Wandung der Gewindenut unter keinen Umständen bei dem Ausschruppen der Gewindenuten durch die andere Flanke zu leiden hat. Dasselbe läßt sich auch erreichen, wenn die Mittenentfernungen der Schneidzähne vom Ende des Schneidzeuges nach dem Anschnitt hin abnehmen, indem alsdann die Zerspanung· der Gewindenut in Richtung der anderen Flanke erfolgt.lowering wall of the thread groove under none Circumstances suffer when roughing out the thread grooves through the other flank Has. The same can be achieved if the center-to-center distances of the cutting teeth from the end of the cutting tool after the first cut decrease by then cutting the thread groove in the direction of the other Edge occurs.
