Description
Die Erfindung betrifft eine Schleifmaschine für wellenförmige, an beiden Enden eingespannte Werkstücke, mit einem Werkstückspindelstock und einem Reitstock, zwischen denen das Werkstück einspannbar ist, mit mindestens zwei Schleifeinheiten.The The invention relates to a grinding machine for undulating, Workpieces clamped at both ends, with a workpiece headstock and a tailstock, between which the workpiece can be clamped is, with at least two grinding units.

derartige Schleifmaschine ist aus der
Es ist die Aufgabe der vorliegenden Erfindung die Bearbeitungszeit für die Werkstücke zu verkürzen und eine entsprechende Vorrichtung aufzuzeigen.It the object of the present invention is the machining time for the workpieces to shorten and one show appropriate device.
Gelöst wird diese Aufgabe durch eine Vorrichtung nach Anspruch 1.Solved this object is achieved by a device according to claim 1.
Der Kerngedanke der Erfindung besteht darin das Werkstück zwischen zwei gegenüberliegenden Schleifeinheiten anzuordnen und gleichzeitig durch ein Stützelement abzustützen. Bei dieser Anordnung heben sich die Normalkomponenten der Zerspankräfte gegenseitig auf und die tangential auf das Werkstück einwirkenden Zerspankräfte werden vom Stützelement aufgenommen. Lediglich die in Richtung der Werkstücklängsachse wirkenden Kräfte werden durch Werkstückspindel- und Reitstock kompensiert. Durch die symmetrische Anordnung und das gleichförmige Zustellen der Schleifeinheiten und des Stützelements kann die Werkstückdurchbiegung vernachlässigt werden. Auf diese Weise sind hohe Zustellgeschwindigkeiten möglich und die Bearbeitungszeit für die Werkstücke kann deutlich verkürzt werden. Bei einer vorteilhaften Ausführung werden vor dem Schleifvorgang die Durchmesser der Schleifscheiben und des zu bearbeitenden Werkstücks bestimmt und der erforderliche Zustellweg zur Erzielung eines vorgegebenen Werkstückdurchmessers berechnet. Anschließend werden die Schleifscheiben und das Stützelement entsprechend zugestellt. Bei Bedarf können zur Erzielung eines gewünschten Schleifergebnisses zusätzliche Relativbewegungen zwischen Werkstück und Schleifeinheiten in Richtung der Werkstücklängsachse ausgeführt werden.Of the Core idea of the invention is the workpiece between to arrange two opposite grinding units and simultaneously supported by a support element. In this arrangement, the normal components of Zerspankräfte lift on each other and the tangential acting on the workpiece Cutting forces are absorbed by the support element. Only in the direction of the workpiece longitudinal axis acting forces are generated by workpiece spindle and tailstock compensated. Due to the symmetrical arrangement and the uniform infeeds of the grinding units and the support element can neglect the work piece deflection become. In this way, high delivery speeds are possible and the processing time for the workpieces can be shortened significantly. In an advantageous embodiment Before grinding, the diameter of the grinding wheels and the workpiece to be machined and determines the required Feed path to achieve a given workpiece diameter calculated. Subsequently, the grinding wheels and the support element delivered accordingly. If necessary you can additional to achieve a desired grinding result Relative movements between workpiece and grinding units in Direction of the workpiece longitudinal axis are executed.
