Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den gewöhnlichen, bisher angewendeten Nutenfräsern war es nicht möglich, eine Nut in einem Schnitt zu fräsen, da das infolge der gebräuchlichen Aussparung des Fräsers stehenbleibende Material des Werkstückes den Fräser am Vorschub hinderte.With the usual slot milling cutters used up to now, it was not possible to create a slot to be milled in one cut, as this is due to the common recess in the milling cutter remaining material of the workpiece prevented the milling cutter from advancing.

Den Gegenstand der vorliegenden Erfindung bildet ein Nutenfräser, dessen Hauptkennzeichen darin bestehen, daß ein exzentrisch zur Seelenachse des Fräsers gebohrtes Loch die Schneidkanten in der Weise schneidet, daß eine der Schneidkanten bis zur Seelenachse stehen bleibt, während von den übrigen Schneidkanten ein Stück von der Länge der Sehne des sie schneidenden Bogens des Lochkreises wegfällt.The subject of the present invention is a slot milling cutter, the main characteristic of which is consist in that a hole drilled eccentrically to the core axis of the milling cutter cuts the cutting edges in such a way that that one of the cutting edges remains up to the axis of the soul, while of the rest Cutting edges a piece the length of the chord of the arc of the bolt circle that intersects them ceases to exist.

Ein derartig konstruiertes Werkzeug gestattet, eine Nut in einem einzigen Schnitt zu fräsen, da die bis zur Seelenachse laufende Schneidkante das von den anderen Schneidkanten stehenbleibende Material sicher wegnimmt, so daß eine vollkommen ebene Grundfläche der zu fräsenden Nut entsteht, und der Vorschub des Fräsers ohne Hindernisse vor sich gehen kann.A tool constructed in this way allows a groove to be made in a single cut to mill, since the cutting edge running up to the core axis is that of the others Cutting edges safely removes remaining material, so that a completely flat The base area of the groove to be milled is created and the cutter feeds without obstacles can go on.

Beiliegende Zeichnung veranschaulicht einen derartigen Fräser in zwei Ansichten, und zwar zeigtThe accompanying drawing illustrates such a milling cutter in two views, and although shows

Fig. ι eine Seitenansicht undFig. Ι a side view and

Fig. 2 den Grundriß derselben.Fig. 2 is the plan view of the same.

Die Anordnung der Schneidrippen α selbst ist beliebig, jedoch so, daß die Schneidkanten b nach der Seelenachse zu laufen. Das in der Richtung der Fräserachse gebohrte Loch c ist um das Stück d, welches dem halben Lochdurchmesser entspricht, exzentrisch gesetzt, und zwar in der Weise, daß die Schneidkanten mit Ausnahme einer einzigen in den Punkten e und f geschnitten werden.The arrangement of the cutting ribs α itself is arbitrary, but in such a way that the cutting edges b run along the axis of the core. The hole c drilled in the direction of the cutter axis is set eccentrically around the piece d, which corresponds to half the hole diameter, in such a way that the cutting edges are cut at points e and f with the exception of a single one.
