Description

DEUTSCHESGERMAN

Die Erfindung bezieht sich auf ein Werkzeug für spanabnehmende Bearbeitung mit in eine Ausnehmung des Halters eingesetzter Schneide.The invention relates to a tool for cutting machining with a recess cutting edge inserted in the holder.

Es ist bekannt, derartige Schneiden, die meist in Form von Plättchen verwendet werden, an einen Werkzeughalter aus Stahl anzulöten, sofern die Plättchen aus einem lötbaren Werkstoff bestehen. Nach einer anderen bekannten Art erfolgt die Befestigung der Schneidplatten am Werkzeughalter durch eine Klemmverbindung mittels Schrauben od. dgl. Dabei werden vielfach infolge eines örtlichen Druckes die meist sehr spröden Schneidplatten beschädigt oder gar zerstört.It is known that cutting edges of this type, which are mostly used in the form of platelets, are attached to a Tool holder made of steel to be soldered, provided that the plates are made of a solderable material. To Another known type is the attachment of the cutting inserts to the tool holder by a Clamping connection by means of screws or the like. Often, as a result of local pressure, the mostly very brittle cutting inserts damaged or even destroyed.

Bei einer anderen bekannten Befestigungsart wird die Schneidplatte in eine Aussparung am Halter eingeschrumpft, indem die kalte Schneidplatte in die durch die Erwärmung des Halters erweiterte Aussparung eingelegt wird, in der die Schneidplatte durch die Schrumpfspannungen festgehalten wird. Aber auch hier ist die Gefahr einer Beschädigung der spröden Schneidplatte nicht ganz vermieden, insbesondere wenn die Aussparung nicht ganz exakt und maßhaltig gearbeitet ist oder die Schneidplatte geringe Maßabweichungen aufweist. Diese Gefahr ist bei dem erfindungsgemäßen Werkzeug vermieden!, da hier unabhängig von etwaigen Maßabweichungen ein gleichmäßiger Klemmdruck erzielt wird.In another known type of fastening, the cutting insert is shrunk into a recess on the holder, by placing the cold cutting insert in the recess that has been enlarged by the heating of the holder is inserted, in which the insert is held by the shrinkage stresses. but Here too, the risk of damage to the brittle cutting insert is not entirely avoided, in particular if the recess is not made exactly and true to size or the cutting insert has minor dimensional deviations having. This risk is avoided with the tool according to the invention, since it is independent here an even clamping pressure is achieved from any dimensional deviations.

Die Erfindung ist dadurch gekennzeichnet, daß die in eine Ausnehmung des Werkzeughalters eingesetzte Schneide mit einem Werkstoff umgössen ist, dessen Dichte im flüssigen Zustand größer ist als im festen Zustand. Eine derartige Eigenschaft hat beispielsweise Wismut, das im flüssigen Zustand eine Dichte von 10,055, im gegossenen Zustand eine Dichte von 9,82 g/cm3 hat.The invention is characterized in that the cutting edge inserted into a recess of the tool holder is encapsulated with a material whose density is greater in the liquid state than in the solid state. Bismuth, for example, has such a property, which has a density of 10.055 in the liquid state and a density of 9.82 g / cm3 in the cast state.

Ein Ausführungsbeispiel ist in der Zeichnung gezeigt, in der ein erfindungsgemäßes Werkzeug in der Seitenansicht, teilweise geschnitten (Fig. 1), und in der Vorderansicht (Fig. 2) dargestellt ist.An embodiment is shown in the drawing, in which a tool according to the invention in the Side view, partially in section (Fig. 1), and shown in the front view (Fig. 2).

Der Werkzeughalter 1 weist die Ausnehmung 1 α auf, in die die Keramikschneidplatte 2 eingesetzt ist.The tool holder 1 has the recess 1 α into which the ceramic cutting plate 2 is inserted.

Der Zwischenraum 3 ist mit Wismut oder einer Wismutlegierung ausgegossen. Bei der Erstarrung dehnt sich die Vergußmasse entsprechend der Dichteabnahme aus und preßt dadurch die Schneidplatte unter gleichmäßiger Druckverteilung in der Ausnehmung 1 a fest, wobei die gegenüber dem Halter und der Schneide weichere Vergußmasse als Druckkissen dient.The space 3 is filled with bismuth or a bismuth alloy. During solidification, the potting compound expands according to the decrease in density and thereby presses the cutting plate firmly in the recess 1 a with uniform pressure distribution, the potting compound, which is softer than the holder and the cutting edge, serving as a pressure pad.
