Description

Der Stirnfräser vorliegender Erfindung soll dann verwendet werden. w6nn Flächen gefräst werden sollen, bei denen der Fräser in der Richtung der Achse an das Werkstück heran geführt wird. Der Fräser hat die bekannten Stirnzähne α in der Anordnung, daß diese untör einem Winkel α zum Radius gefräst sind (siehe Fig. 2). Infolgedessen eilt die innere Kante c des Stirnzahnes im gleichen Sinne der Drehrichtung vor.The end mill of the present invention is then to be used. w6nn surfaces are to be milled in which the milling cutter is guided towards the workpiece in the direction of the axis. The milling cutter has the known face teeth α in the arrangement that these are milled at an angle α to the radius (see FIG. 2). As a result, the inner edge c of the front tooth leads in the same sense of the direction of rotation.

Die Stirnseite des Fräsers besitzt eine radiale Einbohrung von dem Durchmesser e und der Tiefe /V Parallel zur Zahnschneidkante a sind Einschnitte von der Breite b eingefräst, die bis zur nächsten Schneidkante gehen, so daß an der inneren Kante c ein1 spitzer Winkel β entsteht; durch den Einschnitt b . erhält die innere Kante c einseitig den Schnittwinkel β (Fig. 2), wodurch die innere Kante cThe end face of the cutter has a radial single bore of the diameter e and the depth / V parallel to the tooth cutting edge A are incisions of a width b milled to go to the next cutting edge, so that at the inner edge c a 1 acute angle β is formed; through the incision b . the inner edge c receives the cutting angle β on one side (Fig. 2), whereby the inner edge c

beim seitlichen Vorschub des Stirnfräsers den beim Einsetzen entstehenden inneren Zapfen von dem Durchmesser e wegfräst. ' Der Einschnitt b erleichtert den Austritt der in der Mitte stehenden Frässpäne nach außen. Die Flankenschneiden des Fräsers können auch. unter einem Winkel γ (Fig. 1) zur Achse gelegt werden, wodurch an der Schneidkante α ein besserer Schnitt entsteht und die Späne besser abgehoben werden.When the face milling cutter advances laterally, mills away the inner journal from the diameter e which is created during insertion. 'The incision b facilitates the exit of the milling chips standing in the middle to the outside. The flank cutting edges of the milling cutter can also. be placed at an angle γ (Fig. 1) to the axis, whereby a better cut is created at the cutting edge α and the chips are better lifted.

. In einer weiteren Ausführungsform des 3c Fräsers nach Fig. 3 besitzt der Stirnfräser an den Flankenschneiden eine Fase d, die radial nach . außen ausläuft und dem Fräser einen besseren Umfangsschnitt gibt. Dadurch wird der Winkel α an der Umfangsschneidkante 0°, dagegen bleibt der Winkel α an der inneren. Schneidkante bestehen.. In a further embodiment of the 3c milling cutter according to FIG. 3, the face milling cutter has a chamfer d on the flank cutting edges which radially follows. runs out on the outside and gives the cutter a better circumferential cut. As a result, the angle α at the circumferential cutting edge is 0 °, while the angle α remains at the inner one. Cutting edge exist.

Es wird durch solchen Fräser das Fräsen wesentlich erleichtert und befördert.Milling is considerably facilitated and promoted by such milling cutters.
