Bei Verdrehen der Einstellkappe 23 schraubt sich diese in den Ansatz 19 hinein oder aus diesem heraus. Die Distanz des aus der Ausbuchtung 23' vorstehenden Teiles des Fräsers 22 mit der chneide 22' lässt sich damit verändern und die Tiefe der Fräsung 10 esp. Gravierung innert bestimmten Grenzen einstellen. Die im Ansatz 19 befindliche Schraube 18 greift den hohlzylindrischen Vandteil der Einstellkappe 23 an und hält diese fest. iner adjustment cap 23. The milling cutter 22 passes through the hole 24 in the apex of the adjusting cap 23. The cutting edge 22 'of the' cutter 22 projects somewhat in relation to the bulge 23 '. The adjusting cap 23, which partially engages in the extension 19, is provided in the peripheral wall with an external thread 26, 5 richly screwed to the internal thread 27 of the extension 19> t. When the adjusting cap 23 is rotated, it screws into or out of the projection 19. The distance of the part of the milling cutter 22 projecting from the bulge 23 'with the cutting edge 22' can thus be changed and the depth of the milling 10 esp. Set engraving within certain limits. The screw 18 located in the shoulder 19 engages the hollow cylindrical Vand part of the adjusting cap 23 and holds it in place.

und dem Fräsgerät 9 drücken den Fräser 22 auf den Bearbeitungskörper A. Die Schneide 22' des Fräsers 22 greift entsprechend der Einstellkappe 23 mehr oder weniger in das Bearbeitungsstück A ein, und die Ausbuchtung 23' passt sich der Bearbeitungsfläche selbsttätig genau an. Der Fräser 22 bleibt immer im gleichen Abstand zum Bearbeitungskörper A, auch wenn die Formen der Oberfläche sich ändern. Es wird dabei eine gleichmässige Strichfräsung resp. Gravur erzeugt. and the milling device 9 press the milling cutter 22 onto the machining body A. The cutting edge 22 'of the milling cutter 22 engages more or less in the machining piece A in accordance with the adjusting cap 23, and the bulge 23' automatically adapts itself precisely to the machining surface. The milling cutter 22 always remains at the same distance from the machining body A, even if the shapes of the surface change. There is a uniform line milling resp. Engraving creates.

Das Fräsgerät 9 lässt sich bei Nichtgebrauch nach Lösung der Schraube 18 wegnehmen und für andere Fräs- oder Bohrarbeiten verwenden. The milling device 9 can be removed when the screw 18 is not in use and can be used for other milling or drilling work.

Das ästhetische Aussehen der erzeugten Gravierungen auf Bearbeitungskörpern, welche Hinweis-, Orientierungs-, Reklame- oder Anzeigetafeln sein können, wird beträchtlich verbessert, wenn deren sichtbare Oberflächen gewölbte Konturen besitzen. Die drei Achsenbewegungen des Führungsarmes 7 mit dem Fräser 22 ermöglichen die Bearbeitung dreidimensionaler Bearbeitungskörper mit einer gewölbten Oberfläche. The aesthetic appearance of the engravings produced on processing bodies, which can be information, orientation, advertising or display boards, is considerably improved if their visible surfaces have curved contours. The three axis movements of the guide arm 7 with the milling cutter 22 enable the machining of three-dimensional machining bodies with a curved surface.

Die Schablone28' (Fig. 3) kann die Gestalt eines Spielplanes haben, so dass aus dem dreidimensionalen Bearbeitungskörper A' (Fig. 3) ein auf Strichen basierendes Spielbrett, wie beispielsweise ein sogenanntes Mühle-, Puffspiel usw. hergestellt werden kann. Der dreidimensionale Bearbeitungskörper A, A' ist beim Fräsen von Spielplanen durch Klemmorgane B auf dem Tisch 2 fixiert. The template 28 '(FIG. 3) can have the shape of a game board, so that a three-dimensional machining board A' (FIG. 3) can be used to produce a dashboard-based game board, such as a so-called mill, puff game, etc. The three-dimensional processing body A, A 'is fixed on the table 2 by means of clamping elements B when milling game boards.

The milling device 9 is formed by a removable, lever which, on the one hand, a motor-driven milling cutter, conventional, electromotively driven drive unit, and on the other hand, a spindle guide 16 guided by templates or cartridges, the stepped guide ring 17 button owns. For engraving three-dimensional shaped bodies 60 and is locked in place by the screw 18. The pern with a strongly irregularly curved surface on the guide ring 17 partially engages in a hollow cylindrical visible side, such devices are unusable. The need for attachment 19 on the free end part of the guide arm 7 and in improvement of the aesthetic appearance, especially in the case of a large one, is supported by the screw 18, which engages the spindle guide part 16 with signs such as inscriptions in uniform manner. The forward lines from the spindle guide part 16 on a curved base are considerable. Up to now, 65 spindles 20 have been provided with a chuck 21, which can only be produced by time-consuming manual work, which the cutter 22 is clamped in. The latter is cylindrical
