Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur spanabhebenden Bearbeitung von Werkstücken, wie Kurbelwellen, Nockenwellen oder ähnlich geformten Teilen mit runden, exzentrisch rund umlaufenden oder unrunden Oberflächen.The invention relates to a method and a device for machining workpieces, such as crankshafts, camshafts or similarly shaped parts with round, eccentrically circular or non-circular surfaces.

Es ist die Aufgabe der vorliegenden Erfindung ein Verfahren mit einer verkürzten Zykluszeit aufzuzeigen und bei einer Vorrichtung zur Durchführung des Verfahrens die Zugänglichkeit zu verbessern. Diese Aufgabe wird gelöst mit einem Verfahren nach Patentanspruch 1 und einer Vorrichtung nach Patentanspruch 7. Vorteilhafte Ausführungen ergeben sich aus den Unteransprüchen.It is the object of the present invention to provide a method with a shortened cycle time and to improve accessibility in a device for carrying out the method. This object is achieved with a method according to claim 1 and a device according to
Gemäß einem vorteilhaften Aspekt der Erfindung sind Schrupp- und Schlichtfräser auf gegenüberliegenden Seiten einer vertikalen Spindelachse angeordnet. Sie sind daher zumindest teilweise gleichzeitig an der gleichen oder an verschiedenen zu bearbeitenden Werkstückoberflächen in Eingriff. Ein Bearbeitungszyklus beginnt mit der Bearbeitung durch den Schruppfräser. Nach einer halben Umdrehung des Werkstücks gelangt die geschruppte Werkstückoberfläche in den Wirkbereich des Schlichtfräsers und wird dann von diesem geschlichtet. Sobald der Schrupp- oder Schlichtfräser eine Umfangsfläche fertig bearbeitet haben, wechseln sie zur nächsten, so dass sämtliche zu bearbeitenden Flächen nacheinander mit einer halben Umdrehung Versatz geschruppt und geschlichtet werden.According to an advantageous aspect of the invention, roughing and finishing cutters are arranged on opposite sides of a vertical spindle axis. They are therefore at least partially engaged simultaneously on the same or on different workpiece surfaces to be machined. A machining cycle starts with the roughing cutter. After half a revolution of the workpiece, the scraped workpiece surface passes into the effective range of the finishing cutter and is then sized by this. As soon as the roughing or finishing cutters have finished one peripheral surface, they change over to the next, so that all the surfaces to be machined are successively roughed and finished with a half turn offset.
Analog zur Bearbeitung der Mantelflächen können Flanschflächen oder beispielsweise Planschultern von Kurbelwellen zeitversetzt geschruppt und geschlichtet werden. Bei der Vorrichtung zur Durchführung des Verfahrens sind der Spindelstock und die Frässpindeln mit vertikal verlaufenden Achsen nebeneinander angeordnet. Sie sind daher von der Bedienseite her besonders gut zugänglich.Similar to the machining of the lateral surfaces flange surfaces or, for example, plan shoulders of crankshafts can be roughed and finished with a time lag. In the apparatus for carrying out the method of the headstock and the milling spindles are arranged side by side with vertical axes. They are therefore particularly accessible from the operating side.
Im Folgenden wird die Erfindung an Hand eines Ausführungsbeispiels näher beschrieben.The invention will be described in more detail below with reference to an exemplary embodiment.

Nach dem Pendelverfahren können ebenso auch unrunde Flächen, z. B. Nocken von Nockenwellen bearbeitet werden.After the pendulum method as well as non-circular surfaces, z. B. cams are processed by camshafts.
