Abstract

The milling cutters (2) between two saw blades (1) have teeth, whose width projects outside the cutter body by an amount (B). By suitable angular positioning of the cutters, the teeth on one can project into the spaces of the other. A desired milling cut width between the two saw blades is then achieved by choosing a suitable thickness of distance ring (3) between the milling cutters. USE/ADVANTAGE - Only a small number of milling cutter widths need be stocked to produce desired variety of cut widths.

Description

Es sind zwischen Sägeblättern angeordnete Fräser bekannt, deren Schnittbreite, die sich aus der Summe der Schnittbreiten von mehreren Fräsern zusammensetzen kann, genau dem Abstand der Sägeblätter entspricht. Da diese Abstände je nach gewünschter Brettdicke sehr unterschiedlich sind, ist eine Vielzahl von Fräsern mit unterschiedlicher Schnittbreite erforderlich.They are milling cutters arranged between saw blades known whose cutting width, which results from the Sum of the cutting widths of several cutters can put together exactly the distance of the saw blades corresponds. Since these distances depend on the desired Board thickness are very different is a variety of milling cutters with different cutting widths required.

Der Erfindung liegt die Aufgabe zugrunde, ein Fräser­ system zu schaffen, das mit wenigen Fräserbreiten eine Vielzahl von Fräserschnittbreiten ermöglicht.The invention has for its object a router system to create that with a few router bits enables a large number of cutter cutting widths.

Das erfindungsgemäße Fräsersystem weist jeweils mindestens zwei Fräser auf, die mindestens auf einer Seite axial weit überstehende Zähne aufweisen und die Fräser so zueinander angeordnet sind, daß die Zahnüberstände in die Zahnlücken des benachbarten Fräsers ragen. Dadurch ist es möglich, zwischen den Fräsern einfache Distanzringe anzuordnen, deren Dicke die Schnittbreite proportional verändert, wobei die maximale Distanzringdicke gleich der Summe der einander zugewandten Zahnüberstände sein kann. The cutter system according to the invention has in each case at least two cutters on at least one Side axially protruding teeth and the milling cutters are arranged so that the Tooth projections in the tooth gaps of the neighboring one Cutter stick out. This makes it possible to switch between the Simple spacer rings to arrange their thickness the cutting width changes proportionally, the maximum spacer ring thickness equal to the sum of tooth protrusions facing each other.  

Eine Ausführungsform weist Zahnüberstände auf beiden Seiten der Fräser auf, die in Löcher bzw. Ausnehmungen der Sägeblätter ragen können, wenn keine Distanzringe zwischen Fräser und Sägeblatt angeordnet sind.One embodiment has tooth protrusions on both Sides of the milling cutters that are in holes or recesses the saw blades may protrude if there are no spacer rings are arranged between the milling cutter and the saw blade.

Fig. 1 zeigt hälftig eine Sägeblatt/Fräser-Kombination in axialer Sicht mit einem Sägeblatt (1) und die um etwa eine halbe Zahnteilung versetzten Fräser (2.1) und (2.2) mit dem dazwischen verdeckt angeordneten Distanzring (3) und der Welle (4). Fig. 1 shows half of a saw blade / cutter combination in axial view with a saw blade ( 1 ) and the cutters ( 2.1 ) and ( 2.2 ) offset by about half a tooth pitch with the spacer ring ( 3 ) and the shaft ( 4 ).

Fig. 2 zeigt Fig. 1 nach dem Schnitt I-II in radialer Sicht mit dem Sägenabstand D, der der Dicke der Fräser (2.1) und (2.3) ohne die Schneidenüberstände (B) plus der Dicke (A) des Distanzrings (3) entspricht, wobei A maximal B1 + B3 sein kann. Der Überstand B2 greift durch ein Loch im Sägeblatt (1), so daß zwischen dem Fräser (2.3) und der Säge (1) ebenfalls Distanzringe angeordnet sein können mit der maximalen Dickensumme = B2. Fig. 2 shows Fig. 1 after the section I-II in a radial view with the saw spacing D, the thickness of the milling cutters ( 2.1 ) and ( 2.3 ) without the cutting edge protrusions (B) plus the thickness (A) of the spacer ring ( 3 ) corresponds, where A can be at most B 1 + B 3 . The overhang B 2 reaches through a hole in the saw blade ( 1 ), so that spacer rings with the maximum thickness sum = B 2 can also be arranged between the milling cutter ( 2.3 ) and the saw ( 1 ).

Claims (2)

1. Zwischen je zwei Sägeblättern angeordneter Fräser, dadurch gekennzeichnet, daß der Fräser (2.3) mindestens auf einer Seite Zähne aufweist mit einem axialen Schneidenüberstand (B) von mindestens 2 mm und, daß der benachbarte Fräser (2.1) und/oder (2.2) in Umfangsrichtung um ca. eine halbe Zahnteilung versetzt angeordnet ist und somit die axial überstehenden Fräserschneiden in Lücken des benachbarten Fräsers (2.1) oder (2.2) aufnehmbar sind und zwischen dem Fräser (2.3) und dem Sägeblatt (1) und/oder dem Fräser (2.1) bzw. (2.2) Distanzringe (3) einbaubar sind, deren Dicke (A) kleiner ist als die Summe der Schneidenüberstände (B) der Fräser (2) oder des Fräsers (2) auf der oder den Seiten, gegen die der Distanzring (3) anliegt.1. Between two saw blades arranged cutter, characterized in that the cutter ( 2.3 ) has teeth on at least one side with an axial cutting protrusion (B) of at least 2 mm and that the adjacent cutter ( 2.1 ) and / or ( 2.2 ) is arranged offset in the circumferential direction by about half a tooth pitch and thus the axially projecting cutter edges can be received in gaps of the adjacent cutter ( 2.1 ) or ( 2.2 ) and between the cutter ( 2.3 ) and the saw blade ( 1 ) and / or the cutter ( 2.1 ) or ( 2.2 ) spacer rings ( 3 ) can be installed, the thickness (A) of which is smaller than the sum of the cutting edge protrusions (B) of the milling cutters ( 2 ) or the milling cutter ( 2 ) on the side or sides against which the spacer ring ( 3 ) is present. 2. Zwischen je zwei Sägeblättern angeordneter Fräser nach Anspruch 1, dadurch gekennzeichnet, daß die axial überstehenden Fräserschneiden der Fräser (2) in eine konzentrische Ringnut des Sägeblattes (1) ragen.2. Between two saw blades arranged cutter according to claim 1, characterized in that the axially projecting cutter edges of the cutter ( 2 ) protrude into a concentric annular groove of the saw blade ( 1 ).
