Description
Den Gegenstand der Erfindung bildet ein Fräser mit eigenartig ausgebildeten Schneiden.The subject of the invention is a milling cutter with peculiarly designed cutting edges.
Das Neue an demselben besteht darin, daß er über seine ganze Länge am Umfang mit sich kreuzenden Rechts- und Linksspiralnuten versehen ist, wobei die Anzahl der rechten und linken Nuten gleich oder verschieden sein kann. .What is new about it is that it is with it over its entire length intersecting right and left spiral grooves is provided, the number of right and left grooves can be the same or different. .
Fräser mit rechts- und linksgängig verlaufenden Spiralnuten sind bekannt, doch reichen bei diesen die Spiralnuten nicht über die ganze Länge des Fräsers.Milling cutters with right-hand and left-hand spiral grooves are known, but they are sufficient in these, the spiral grooves do not run over the entire length of the milling cutter.
Auf der Zeichnung zeigen:On the drawing show:
Fig. ι eine Ansicht des Fräsers und
Fig. 2 eine Abwicklung hierzu.Fig. Ι a view of the milling cutter and
Fig. 2 shows a development of this.
Nach dem dargestellten Ausführungsbeispiel besteht der Fräser α (Fig. ι und 2) aus Rechtsund Linksspiralnuten b und vereinigt somit die Eigenschaften eines rechts- und linksgenuteten Fräsers in vollkommener Weise, da sich an jeder Stelle seiner ganzen Breite die Achsendrücke gegenseitig aufheben.According to the illustrated embodiment, the milling cutter α (Fig. 1 and 2) consists of right and left spiral grooves b and thus combines the properties of a right and left grooved milling cutter in a perfect way, since the axial pressures cancel each other out at every point along its entire width.
Neben äußerst ruhigem Gang ergibt der neue Fräser den bisherigen bekannten Konstruktionen gegenüber bedeutend erhöhte Lei- as stung, wobei auch bei tiefen Schnitten ein sogenanntes Rattern vermieden wird und glatte Flächen erzeugt werden.In addition to extremely smooth walking, the new milling cutter results in the previously known designs compared to significantly increased performance, even with deep cuts so-called chattering is avoided and smooth surfaces are generated.
Der. Fräser α kann natürlich in jeder zweckdienlichen Größe und Form, insbesondere mit verjüngend verlaufender bzw.· konischer Form hergestellt werden, wobei die Anzahl der rechten und linken Nuten δ gleich oder verschieden sein kann.Of the. Milling cutters α can of course be produced in any suitable size and shape, in particular with a tapering or conical shape, with the number of right and left grooves δ being the same or different.
