Description

Um Kugeln oder Teile von Kugelflächen herzustellen, bedient man sich in den meisten Fällen einer Schablonendrehbank, bei der ein Drehmesser an dem sich drehenden Werkstück im Kreisbogen herumgeführt wird. Diese Führung erfolgt als kreisförmiger Vorschuh um eine senkrecht zum Drehmesser stehende lotrechte Achse. Man kann aber auch dem Drehmesser schon von vornherein die Form :des zu drehenden Kreisprofils geben, was jedoch bei der Bearbeitung den Nachteil eines zu großen Spanangriffes mit untereinander sehr verschiedenen Schnittwinkeln und Schnittgeschwindigkeiten hat. Eine an diese Art anknüpfende Herstellung ist nun das Fräsen der Kugelflächen, bei dem man bisher ebenfalls an die vorgenannten Profilformen des sich nunmehr auch selbst drehenden Werkzeuges gebunden war.In order to produce spheres or parts of spherical surfaces, one uses in most cases a template lathe with a rotary knife attached to it rotating workpiece is guided around in a circular arc. This guidance takes place as a circular Shoe around a perpendicular axis perpendicular to the rotary knife. But you can the shape of the rotary knife from the start: the circular profile to be rotated give, which has the disadvantage of too great a chip attack when machining with very different cutting angles and cutting speeds Has. A production linked to this type is the milling of the spherical surfaces, in which one has so far also used the aforementioned profile shapes even turning tool was bound.

Die Erfindung vereinfachte nun die Arbeiten an den für die Herstellung von Kugelflächen vorgesehenen Fräsmaschinen durch die Verwendung eines Fräskopfes, der in besonderer Weise auf das Werkstück einwirkt, wobei die Drehmesser dieses Fräskopfes nach einem Kreis an dem um eine andere Achse sich drehenden Werkstück spanabhebend angesetzt werden.The invention now simplified the work on the production milling machines provided by spherical surfaces through the use of a milling head, which acts in a special way on the workpiece, the rotary knives this Milling head according to a circle on the workpiece rotating around another axis can be applied by machining.

In der Zeichnung des dargestellten Ausführungsbeispfeles der Erfindung bezeichnet i das Werkstück, welches um .die Achse 2 der nicht näher dargestellten Einspannvorrichtung dreht. Die Bearbeitung des Werkstückes i erfolgt von einem senkrecht dazu stehenden Fräserschlitten 3 aus, der an seinem konischen Drehzapfen q. deii,Fräskopf'5 mit seinen axial herausstehenden Messern 6 trägt. Die Messer 6 drehen um die Achse 7 und beschreiben dabei Kreise 8,. die sich auf dem mehr oder weniger langsam darunter hinwegdrehenden Werkstück i als eng nebeneinanderliegende Teile von Schraubenlinien abzeichnen. Die Schneidkante 9 jedes Messers 6 nimmt dabei stets so viel an Spanstärke entlang der Kreislinie 8 weg, als das Werkstück i sich seit dem Angriff des vorhergehenden. Messers weitergedreht hat. Dadurch entsteht in der Schnittebene der Messerspitzen 9, .die gleich einem Ring sich an die Kugelfläche legen, das gewünschte Kreisprofil so, ohne daß dafür besondere Messerformen erforderlich werden, sondern ein ganz gewöhnlicher Messerkopf, wie er beispielsweise zum Planfräsen verwendet wird, genügt, um eine Kugelfläche herzustellen. Dabei ist es gleichgültig, ob es sich -um eine nach außen oder nach innen gewölbte Fläche handelt. Im letztgenannten Falle muß dann nur der Fräser innerhalb der Kugelfläche liegen.In the drawing of the illustrated Ausführungsbeispfeles of the invention i denotes the workpiece, which around .die axis 2 of the not shown Jig rotates. The workpiece i is machined from a vertical in addition standing milling carriage 3, which on its conical pivot q. deii, milling head '5 with its axially protruding knives 6 carries. The knives 6 rotate around the axis 7 and describe circles 8 ,. which is on the more or less slowly underneath rotating workpiece i as closely spaced parts of helical lines sign off. The cutting edge 9 of each knife 6 always takes so much chip thickness along the circular line 8 away than the workpiece i has been since the attack of the previous one. Has continued to turn the knife. This creates the knife tips in the cutting plane 9, which lie like a ring on the spherical surface, the desired circular profile so, without the need for special knife shapes, but rather a whole Ordinary cutter head, such as that used for face milling, is sufficient, to create a spherical surface. It does not matter whether it is a is an outwardly or inwardly curved surface. In the latter case, must then only the milling cutter will lie within the spherical surface.
