Description
Zum Zweck des Schleifens und Polierens von Tiefdruckformzylindern preßt man eine Schleifscheibe, etwa eine mit Schmirgelleinwand überzogene ebene Holz- oder Gummischeibe, gegen die Oberfläche des Kupferzylinders, der auf einer Drehbank oder Schleifmaschine eingespannt ist, und führt sie mit Hilfe einer Leitspindel an der Oberfläche, des . Kupferzylinders entlang. Die Schleif scheibe ist hierbei mit einem besonderen Antrieb· versehen. Um diesen besonderen Antrieb zu ersparen und um die Schleif wirkung zu verbessern, wird erfindungsgemäß einerseits die Spindelachse der Schleifscheibe unangetrieben gegenüber der Senkrechten zur Achse des Werkstückes, wie an sich bekannt, ein wenig geneigt, und anderseits wird der Schleifbelag auf einer elastischen- Unterlage angeordnet, wie an sich gleichfalls bekannt, mit der neuen Gesamtwirkung, daß die ohne Eigenantrieb ihrer Achse wirkende Scheibe bei der Drehung des Zylinders durch die größere einseitige Reibung der gedrückten Zone sicher mitgenommen-wird, während die andere, zum Zylinder gegenläufige Seite der Scheibe, die nur mit geringem Druck am Zylinder anliegt, dabei eine entsprechend Leichte Schleif wirkung an der Zylinderoberfläche zeitigt. -For the purpose of grinding and polishing gravure form cylinders, one presses Sanding disc, such as a flat wooden or sheet covered with emery cloth Rubber washer, against the surface of the copper cylinder that is on a lathe or Grinder is clamped and guides it on the surface with the help of a lead screw, of . Copper cylinder along. The grinding wheel is equipped with a special drive Mistake. To save this special drive and the grinding effect To improve, according to the invention, on the one hand, the spindle axis of the grinding wheel is not driven compared to the perpendicular to the axis of the workpiece, as is known per se, a little inclined, and on the other hand, the abrasive layer is on an elastic base arranged, as is also known per se, with the new overall effect that those without Self-propelled disk acting on its axis as the cylinder rotates greater one-sided friction of the pressed zone is safely carried along while the the other side of the disc, opposite to the cylinder, which only applies a little pressure on the Cylinder, with a correspondingly slight grinding effect on the cylinder surface leads to. -
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung in den Abb. 1 und 2. Der Kupferzylinder α ist auf der Schleifbank b eingespannt und dreht sich unter dem Einfluß einer beliebigen Antriebsvorrichtung c in Richtung des Pfeiles d. Gegen ihn wird in Richtung des Pfeiles e eine mit Schmirgelleinwand überzogene Holzscheibe / gepreßt, die in einem Lagerg· drehbar gelagert ist, das auf einer Leitspindel h sitzt und auf dieser selbsttätig oder von Hand aus in Richtung der Leitspindelachse vorgeschoben wird. Die Scheibe / erhält nun eine ganz geringe Schräge zur Achse des Zylinders a, so daß sie von diesem einseitig mitgenommen wird. Der Überzug von Schmirgelleinwand, der bekanntlich aus mehreren Lagen besteht, wird infolge der Schrägstellung der Scheibe auf der einen Seite leicht zusammengepreßt, während er auf der anderen, nicht gedrückten Seite der Scheibe etwas nachgeben kann und infolgedessen mit ganz geringem Druck am Zylinder anliegt und dadurch eine leichte Schleif wirkung an der Zylinderoberfläche hervorruft. The drawing shows an embodiment of the invention in Figs. 1 and 2. The copper cylinder α is clamped on the grinding bench b and rotates under the influence of any drive device c in the direction of arrow d. Against it, is / pressed a plated with emery cloth wooden disc in the direction of arrow e, which is rotatably mounted in a Lagerg · sitting h on a lead screw and is advanced on this automatically or by hand in the direction of Leitspindelachse. The disc / now receives a very slight slope to the axis of the cylinder a, so that it is carried along on one side by this. The coating of emery cloth, which is known to consist of several layers, is slightly compressed on one side as a result of the inclined position of the disc, while it can give a little on the other, unpressed side of the disc and consequently rests on the cylinder with very little pressure and thereby causes a slight grinding effect on the cylinder surface.
Die Nachgiebigkeit der Schleifscheibe kann auch auf andere Weise erzielt werden, beispielsweise kann die Schmirgelleinwand auf eine Gummiunterlage aufgezogen sein.The compliance of the grinding wheel can also be achieved in other ways, for example the emery canvas can be drawn onto a rubber pad.
