Abstract
The invention relates to an end-milling cutter for mechanical milling, comprising an insert holding element having a clamping shaft and a receiving body, said receiving body being provided with a diametrical open slit on the side which is at a distance from the clamping shaft. An indexable insert consisting of hard metal is detachably positioned in said slit, said insert having two rotationally symmetrical bezels protruding at least past the front side of the receiving body of the insert holding element. The aim of the invention is to be able to guide the coolant to the bezels of the indexable insert through the end-milling cutter. To this end, a coolant channel coaxially extends through the clamping shaft of the insert holding element and continues towards the slit of the receiving body in two separate branches which are, in turn, connected to end channels leading towards the bezels on both sides of the insert.
Description
FINGERFRÄSER MIT WENDESCHNEIDPLATTEFINGER MILLING CUTTER WITH INSERT
Technisches GebietTechnical field
Die Erfindung bezieht sich auf einen Fingerfräser für maschinelle Fräsungen bestehend aus einem Schneidplattenhalter mit einem Spannschaft und einem Aufnahmekörper, der ei- nen diametral durchgehenden, an der vom Spannschaft abliegenden Stirnseite offenen Schlitz hat und aus einer in diesen Schlitz lösbar eingesetzten Wendeschneidplatte aus Hartmetall, die zwei zumindest über die Stirnseite des Auf- nahmekörpers des Schneidplattenhalters vorstehende, mitein- ander drehsymmetrische Schneiden hat.The invention relates to a end mill for machine milling consisting of a cutting insert holder with a clamping shank and a receiving body, which has a diametrically continuous slot open on the end face remote from the clamping shank, and a carbide indexable insert that is detachably inserted into this slot has two, at least over the end face of the receiving body of the insert holder, mutually symmetrical cutting edges.
Stand der TechnikState of the art
Bei Bearbeitungsvorgängen mit Fingerfräsern der gattungsge- mäßen Art wird in dem Bereich, in dem sich die Schneiden der Wendeschneidplatte im Materialeingriff befinden, durch zusätzliche, mitgeführte Vorrichtungen zugeleitet. In der Regel handelt es sich bei dem Kühlmittel um eine Kühl- oder Schneidflüssigkeit, grundsätzlich kann es sich bei dem Kühlmittel auch um Luft handeln.In the case of machining operations with end mills of the generic type, the area in which the cutting edges of the indexable insert are in the material engagement is fed in by additional devices that are carried along. As a rule, the coolant is a coolant or cutting liquid; in principle, the coolant can also be air.
In der Frästechnik gibt es rotierende Fräswerkzeuge, die durchbohrt sind, um durch die Werkzeuge hindurch das Kühlmittel an die Werkzeugschneiden heranzubringen. Dies Fräs- maschinen, in denen solche Fräswerkzeuge verwendet werden
können, haben eine entsprechend ausgebildete Werkzeugaufnahme, um koaxial mit der Rotationsachse das Kühlmittel in das Fräswerkzeug einführen zu können.In milling technology, there are rotating milling tools that are drilled through to bring the coolant through the tools to the cutting edges. These are milling machines in which such milling tools are used can have a suitably designed tool holder in order to be able to introduce the coolant into the milling tool coaxially with the axis of rotation.
Bei Fingerfräsern der eingangs genannten Art gibt es bislang die Kühlmittelzufuhr durch dieses Werkzeug hindurch nicht. Denn ein Durchbohren der aus Hartmetall bestehenden Wendeschneidplatten scheidet aus, weil hierdurch die Festigkeit des Hartmetalls zu sehr beeinträchtigt würde.In the case of end mills of the type mentioned at the outset, there has been no coolant supply through this tool. Drilling through the carbide indexable inserts is ruled out because this would impair the strength of the hard metal too much.
Die ErfindungThe invention
Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Fingerfräser der gattungsbildenden Art zu schaffen, durch den hindurch das Kühlmittel bis an die Schneiden der aus Hartmetall bestehenden Wendeschneidplatte herangeführt werden kann, wobei die für die Führung des Kühlmittels dienen- den Kanäle dort vorgesehen sind, wo die Materialfestigkeit des gesamten Werkzeug nicht beeinträchtigt wird.The invention is therefore based on the object of providing a end mill of the generic type, through which the coolant can be brought up to the cutting edges of the carbide indexable insert, the channels used for guiding the coolant being provided where the material strength of the entire tool is not affected.
Diese Aufgabe wird bei einem gattungsgemäßen Fingerfräser dadurch gelöst, daß sich koaxial durch den Spannschaft des Schneidplattenhalters hindurch eine Kühlmittelkanal erstreckt, der sich zum Schlitz des Aufnahmekörpers hin in zwei Kanalzweigen fortsetzt, an die im Bereich zu beiden Seiten der Schneidplatte zu deren Schneiden hinführende Endkanäle anschließen.
Für die Erfindung ist wesentlich, daß die zu den Schneiden der aus Hartmetall bestehenden Wendeschneidplatte hinfüh- renden Endkanäle sich im Bereich der Flanke des Schlitzes im Aufnahmekörper des Schneidplattenhalters sowie den gegenüberliegenden, sich daran abstützenden Seitenflächen der aus Hartmetall bestehenden Wendeschneidplatte befinden. So muß die Wendeschneidplatte, welche im Schneidplattenhalter diametral zur Rotationsachse angeordnet ist, nicht in Richtung dieser Achse oder parallel dazu durchbohrt werden. Anders verhält es sich beim Schneidplattenhalter selbst, hier ist insbesondere der Kühlmittelkanal im Bereich des Spannschaftes koaxial angeordnet, womit ein erfindungsgemäßer Fingerfräser bei solchen Fräsmaschinen verwendet werden kann, welche die Zuführung des Kühlmittels koaxial mit der Rotationsachse in das Fräswerkzeug hinein ermöglichen.This object is achieved in a generic end mill in that a coolant channel extends coaxially through the clamping shank of the insert holder and extends to the slot of the receiving body in two channel branches, to which end channels leading to the cutting edges in the area on both sides of the insert , It is essential for the invention that the end channels leading to the cutting of the indexable insert made of hard metal are located in the region of the flank of the slot in the receiving body of the indexable insert holder and the opposite side surfaces of the indexable insert made of hard metal which are supported thereon. The indexable insert, which is arranged in the insert holder diametrically to the axis of rotation, does not have to be drilled through in the direction of this axis or parallel to it. The situation is different with the insert holder itself, in particular the coolant channel is arranged coaxially in the region of the clamping shank, with which a finger milling cutter according to the invention can be used in milling machines which allow the coolant to be fed coaxially with the axis of rotation into the milling tool.
Bei ausreichender Dicke kann die Festigkeit der aus Hartme- tall bestehenden Wendeschneidplatte groß genug sein, um die Endkanäle in die Seitenflächen der Schneidplatte einzufor- men. In diesem Fall befindet sich der Übergang zwischen den beiden Kanalzweigen, in denen sich der Kühlmittelkanal im Schaft des Schneidplattenhalters fortsetzt, zu den in die Seitenflächen der Schneidplatte eingeformten Endkanälen im Bereich des Schlitzgrundes im Aufnahmekörper des Schneidplattenhalters .If the thickness is sufficient, the hard metal insert can be strong enough to form the end channels in the side surfaces of the insert. In this case, the transition between the two channel branches, in which the coolant channel continues in the shaft of the insert holder, is to the end channels formed in the side surfaces of the insert in the area of the slot base in the receiving body of the insert holder.
Bei Wendeschneidplatten mit geringerer Dicke können die Endkanäle ganz oder zumindest teilweise in die den Schlitz
des Aufnahmekörpers des Schneidplattenhalters begrenzenden Stützflächen eingeformt sein. Entsprechend divergieren die an den Kühlmittelkanal im Spannschaft des Schneidplattenhalters anschließenden Kanalzweige etwas stärker.In the case of indexable inserts with a smaller thickness, the end channels can be wholly or at least partially in the slot of the receiving body of the insert holder delimiting support surfaces. Accordingly, the channel branches adjoining the coolant channel in the clamping shank of the insert holder diverge somewhat more.
