Description

Die Erfindung bezieht sich :auf einen Schnellstahl-Drehling für allgemeine Metallbearbeitung. Die üblichen Drehlinge müssen einen bestimmten Querschnitt haben, damit sie die beim Drehen notwendige Biegefestigkeit aufweisen. Vor allem darf der Schnellstahl-Drehling bei der Bearbeitung eines Werkstückes nicht vibrieren, da sonst die Maßhaltigkeit des Werkstückes leidet.The invention relates to: to a high-speed steel turning ring for general Metalworking. The usual turning tools must have a certain cross-section, so that they have the necessary flexural strength when turning. Above all, the Do not vibrate high-speed steel lathe when machining a workpiece, because otherwise the dimensional accuracy of the workpiece will suffer.

Wenn die Schneide des Drehlinges stumpf ist, muß meist die ganze der Höhe des Stahles entsprechende Freifläche nachgeschliffen werden. Dabei wird hochwertiges Material unausgenutzt verschliffen.If the cutting edge of the turning tool is blunt, the whole of the Height of the steel corresponding open space must be reground. It is high quality Material sanded down unused.

Um diesem Übel abzuhelfen, ist nach der Erfindung der Drehling parallel zu seiner Auflagefläche in zwei Hälften geteilt, die mit ihren Rückseiten aufeinanderliegen und mindestens an je einem Ende mit einer Schneide versehen sind. Ist der Drehling jetzt stumpf, so dreht man ihn um i8o° und kann die noch unverbrauchte Schneide verwenden. Außerdem ist beim Nachschleifen die abzuschleifende Freifläche wesentlich geringer.In order to remedy this evil, according to the invention, the rotating part is parallel divided into two halves to its support surface, the backs of which lie on top of one another and are provided with a cutting edge at least at one end. Is the turntable now blunt, you turn it 180 ° and you can remove the unused cutting edge use. In addition, the open area to be abraded is essential when regrinding less.

Es ist an sich bekannt, Drehwerkzeuge an beiden Enden mit je einer Schneide zu versehen, die nacheinander in Arbeitsstellung gebracht werden. Ferner ist es auch bekannt. Drehwerkzeuge aus zwei etwa gleichartigen Teilen mit darin hintereinanderliegenden, als Schneidwerkstoff eingefügten härteren Schneidschichten in Längsrichtung so zusammenzuschweißen, daß die Schneidschichten gegeneinander versetzt sind und unter entgegengesetztem Winkel zur gemeinsamen Ebene der beiden Teile liegen. Nach dem Verbrauch einer Schneide des Werkzeuges werden dann die beiden Teile des Werkzeugschaftes so weit abgeschliffen, daß die nächste Schneidschicht des vorher unwirksamen Schaftteiles nunmehr zum Gebrauch geeignet ist, Dieses Werkzeug erfordert verhältnismäßig viel Nacharbeit, wenn eine neue Schneide angeschliffen werden soll.It is known per se, turning tools at both ends with one each To provide cutting edge, which are brought into working position one after the other. Further it is also known. Turning tools from two roughly similar parts with it one behind the other, harder cutting layers inserted as cutting material to be welded together in the longitudinal direction so that the cutting layers against each other are offset and at opposite angles to the common plane of the two Parts lie. After one cutting edge of the tool has been used, the two Parts of the tool shank ground off so that the next cutting layer of the previously ineffective shaft part is now suitable for use, This tool requires a relatively large amount of reworking when a new cutting edge is ground shall be.

In Fig.I, Il und III ist ein Drehling nach der Erfindung in Grundriß; Seiten- und Stirnansicht gezeigt. Der Drehling besteht aus zwei Hälften, die an einem Ende je eine Schneide 2 und 2 aufweisen.In Fig.I, II and III, a rotary element according to the invention is in plan; Side and front views shown. The rotating part consists of two halves that are attached to each have a cutting edge 2 and 2 at one end.

Damit die beiden Drehlinghälften sicher aufeinanderliegen, sind sie an ihren Rückenflächen mit einer zusammenpassenden Spitzverzahnung i, i versehen. .So that the two halves of the rotating part are securely on top of each other, they are on their back surfaces with matching serrations i, i. .

Man kann auch beide Enden jeder Drehlingshälfte mit einer Schneide versehen und diesen je nach Bedarf verschiedene Form geben, so daß dadurch weitere Ersparnisse bei der Arbeit erzielt werden.You can also use a cutting edge at both ends of each half of the turning tool provided and give this different shape as required, so that more Savings can be made at work.
