Fräser mit unterschiedlichen Zahnhöhen und ZahnteilungenMilling cutters with different tooth heights and tooth pitches

Die bekannten Fräser haben den Nachteil, daß sie entweder zu dünne Späne oder unebene Oberflächen erzeugen.The known milling cutters have the disadvantage that they produce either chips that are too thin or uneven surfaces.

Der Erfindung liegt die Aufgabe zugrunde, einen Fräser zu schaffen, der zum großen Teil relativ dicke Späne und glatte Fräsflächen erzeugt.The invention is based on the object of creating a milling cutter which largely produces relatively thick chips and smooth milling surfaces.

Der erfindungsgemäße Fräser weist periodisch abwechselnd ungleich hohe Zähne mit ungleichen Zahnabständen auf, dergestalt, daß die kleinen Zahnabstände vor den hohen Zähnen und die großen Zahnabstände vor den niedrigen Zähnen angeordnet sind, wodurch die hohen Zähne aufgrund der geringen Zahnvorschübe eine glatte Oberfläche erzeugen und die niedrigen Zähne aufgrund der großen Zahnteilung dickere Späne.The milling cutter according to the invention has periodically alternating teeth of unequal height with unequal tooth spacings, such that the small tooth spacings are arranged in front of the high teeth and the large tooth spacings in front of the low teeth, whereby the high teeth produce a smooth surface due to the low tooth feeds and the low teeth produce thicker chips due to the large tooth pitch.

Die einzige Figur zeigt den erfindungsgemäßen Fräser (1) mit den hohen Zähnen (1.1) und den kleinen Zahnabständen (B) und den niedrigen Zähnen (1.2) mit den großen Zahnabständen (A), wobei die hohen Zähne (1.1) mit ihren Spitzen auf dem großen Zahnspitzenflugkreis (R1) liegen und die niedrigen Zähne (1.2) den kleinen Zahnspitzenflugkreis (R2) und die Zähne (1.1) bzw. (1.2) die Zahnhöhendifferenz (H) aufweisen. Zur Gewichtsreduzierung sind die Löcher (1.3) vorgesehen.The single figure shows the milling cutter (1) according to the invention with the high teeth (1.1) and the small tooth spacing (B) and the low teeth (1.2) with the large tooth spacing (A), whereby the high teeth (1.1) lie with their tips on the large tooth tip flight circle (R1) and the low teeth (1.2) have the small tooth tip flight circle (R2) and the teeth (1.1) or (1.2) have the tooth height difference (H). The holes (1.3) are provided to reduce weight.

Claims (4)

1. Fräser dadurch gekennzeichnet, daß die Zähne periodisch abwechselnd ungleiche Höhen und Teilungen aufweisen, dergestalt, daß die hohen Zähne (1.1) auf dem größeren Zahnspitzenflugkreis (R1) liegen und die niedrigen Zähne auf dem kleineren Zahnspitzenflugkreis (R2) liegen und daß die großen Zahnabstände (A) vor den niedrigen Zähnen (1.2) und die kleinen Zahnabstände (B) vor den hohen Zähnen (1.1) sind. 1. Milling cutter characterized in that the teeth have periodically alternating unequal heights and pitches, such that the high teeth (1.1) lie on the larger tooth tip flight circle (R1) and the low teeth lie on the smaller tooth tip flight circle (R2) and that the large tooth spacings (A) are in front of the low teeth (1.2) and the small tooth spacings (B) are in front of the high teeth (1.1). 2. Fräser nach Anspruch 1 dadurch gekennzeichnet, daß mindestens jeweils zwei hohe Zähne (1.1) mit kleinem Zahnabstand (B) hintereinander angeordnet sind und deren Zahnhöhendifferenz kleiner ist als die Zahnhöhendifferenz (H) zwischen den hohen Zähnen (1.1) und den niedrigen Zähnen (1.2). 2. Milling cutter according to claim 1, characterized in that at least two high teeth (1.1) with a small tooth spacing (B) are arranged one behind the other and their tooth height difference is smaller than the tooth height difference (H) between the high teeth (1.1) and the low teeth (1.2). 3. Fräser nach einem oder mehreren der Ansprüche 1 bis 2 dadurch gekennzeichnet, daß der Fräser (1) aus mehreren Scheiben besteht, die in einer Sonderausführung Löcher (1.3) aufweisen. 3. Milling cutter according to one or more of claims 1 to 2, characterized in that the milling cutter (1) consists of several discs which, in a special design, have holes (1.3). 4. Fräser nach einem oder mehreren der Ansprüche 1 bis 3 dadurch gekennzeichnet, daß mindestens auf einer Fräserstirnseite eine Kreissäge angeordnet ist, deren Zähne sich mit den Zähnen (1.1) bzw. (1.2) des Fräsers (1) axial überlappen und etwa den gleichen Flugkreis (R1) bzw. (R2) aufweisen und die Zähne (1.1) bzw. (1.2) in einer Sonderausführung gegen die Zähne der Trägerscheibe des Kreissägeblattes durch entsprechende Dickenreduzierung der Trägerscheibe anliegen. 4. Milling cutter according to one or more of claims 1 to 3, characterized in that a circular saw is arranged at least on one end face of the milling cutter, the teeth of which axially overlap with the teeth (1.1) or (1.2) of the milling cutter (1) and have approximately the same flight circle (R1) or (R2) and the teeth (1.1) or (1.2) in a special design rest against the teeth of the carrier disk of the circular saw blade by correspondingly reducing the thickness of the carrier disk.
