Trennmaschine für die Bearbeitung schwer zerspanbarer Werkstoffe (wie z.B. Hartmetall, Keramik, Glas, Hss).Cutting machine for machining difficult-to-machine materials (such as hard metal, ceramic, glass, Hss).

Für die Zerspanung dieser schwer zerspanbaren Werkstoffgruppe werden schon des längeren Diamant- und CBN-Trennscheiben eingesetzt. Um die Standzeit der Trennscheiben noch zu erhöhen, sollten diese mit Kühlmittel eingesetzt werden.Diamond and CBN cutting discs have long been used to machine this group of materials that are difficult to machine. To increase the service life of the cutting discs, they should be used with coolant.

Bei Trennmaschinen einfacher Bauart werden die Werkstücke im Trockenschliff bearbeitet oder die Werkstücke müssen im Kühlmittelbad in die Spannvorrichtung eingelegt werden.In simple cutting machines, the workpieces are processed using dry grinding or the workpieces must be placed in the clamping device in a coolant bath.

Es gibt auch Trennmaschinen, bei denen die Spannvorrichtung in einem Kühlmittelbehälter mittels einer Kühlmittelpumpe geflutet wird und nach der Bearbeitung das Kühlmittel wieder abgelassen wird.There are also cutting machines in which the clamping device is flooded in a coolant tank using a coolant pump and the coolant is drained again after machining.

Außerdem gibt es Trennmaschinen, die im Naßschliff durch eine Kühlmittelpumpe mit 2-6 bar Druck arbeiten. Diese sind aber mit einer komplizierten Bauweise und dementsprechenden Kosten verbunden.There are also cutting machines that work in wet grinding using a coolant pump with 2-6 bar pressure. However, these have a complicated design and are therefore expensive.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine unkomplizierte Trennmaschine zu schaffen, wobei die Standzeit der Trennscheiben und die Bedienfreundlichkeit im Vordergrund stand.The invention specified in claim 1 is based on the problem of creating an uncomplicated cutting machine, whereby the service life of the cutting discs and the ease of use were the main focus.

Dieses Problem wird mit den im Schutzanspruch 1 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claim 1.

Mit der Erfindung wird erreicht,The invention achieves

- daß die zu bearbeitenden Teile im Trockenbereich eingespannt werden, die Bearbeitung aber unter Kühlung erfolgt- that the parts to be machined are clamped in the dry area but the machining takes place under cooling

— 2 ——2—

- daß ein weicheres Aufsetzen der Trennscheibe auf das Werkstück ermöglicht wird, weil Trennscheibe und Werkzeug in gleicher Richtung aber doch mit unterschiedlichen Geschwindigkeiten bewegt werden- that a softer placement of the cutting disc on the workpiece is possible because the cutting disc and tool are moved in the same direction but at different speeds

- daß eine komplizierte Kühlmittelzufuhr, verbunden mit aufwendiger Verkleidung sich erübrigt.- that a complicated coolant supply, combined with complex cladding, is unnecessary.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Schutzanspruch 2 angegeben.An advantageous embodiment of the invention is specified in claim 2.

Durch das Verdrehen der Führungswelle/Spannvorrichtung können auch Schrägschnitte/Gehrungen hergestellt werden.By turning the guide shaft/clamping device, bevel cuts/mitres can also be made.

Ein Ausführungsbeispiel der Erfindung wird anhand der Figur 1 und 2 erläutert; es zeigen:An embodiment of the invention is explained with reference to Figures 1 and 2; they show:

FunktionsbeschreibungFunctional description

-Fig. 1 - Fig.1

Wird der Hauptarm 1 in Richtung Spannvorrichtung 2 geschwenkt wird gleichzeitig das Hebelgestänge 4, das mit dem Hauptarm 1 durch die Zugstange 3 verbunden ist, über die Drehpunkte nach oben gezogen. Dadurch wird die Führungswelle 5, die auch mit dem Hebelgestänge 4 indirekt durch den Klemmring 6 und den Gleit schuh 7 verbunden ist, nach unten gezogen.If the main arm 1 is pivoted in the direction of the clamping device 2, the lever rod 4, which is connected to the main arm 1 by the pull rod 3, is simultaneously pulled upwards via the pivot points. This causes the guide shaft 5, which is also indirectly connected to the lever rod 4 by the clamping ring 6 and the sliding shoe 7, to be pulled downwards.

•. *•. *

Durch die Anordnung der Hebelverhältnisse entstehen unterschiedliche Wegstrecken. Der Hauptarm 1 legt immer den größeren Weg in vertikaler Richtung gegenüber der Führungswelle 5 in gleicher Zeit zurück. Dadurch erfolgt in jedem Fall ein Zusammentreffen zwischen der Trennscheibe und der Spannvorrichtung 1, was zu einer zwangsläufigen Bearbeitung führt.The arrangement of the lever ratios results in different distances. The main arm 1 always covers the greater distance in the vertical direction compared to the guide shaft 5 in the same time. This always results in a collision between the cutting disc and the clamping device 1, which inevitably leads to machining.

Wird der Kühlmittelbehälter 8 in einer bestimmten Höhe mit Kühlmittel gefüllt, taucht beim Schwenken des Hauptarmes 1 zuerst die Spannvorrichtung 2 und mit Verzögerung die Trennscheibe ins Kühlmittelbad ein und die Bearbeitung findet im Kühlmittel statt.If the coolant tank 8 is filled with coolant to a certain height, when the main arm 1 is pivoted, first the clamping device 2 and, with a delay, the cutting wheel are immersed in the coolant bath and the machining takes place in the coolant.

Fig. 2Fig.2

Durch Lösen der Verbindungsschrauben zwischen dem Klemmring 6 und dem Gleitschuh 7 kann die Führungswelle 5 mit montierter Spannvorrichtung 2 bis zu 45 Grad geschwenkt werden.By loosening the connecting screws between the clamping ring 6 and the sliding shoe 7, the guide shaft 5 with the mounted clamping device 2 can be pivoted up to 45 degrees.
