Abstract
Description
Die Erfindung betrifft einen Konturfräser umfassend einen Schaft, an dem stirnseitig radial verlaufend Schneiden angeordnet sind.The invention relates to a contour milling cutter comprising a shaft on the front radially arranged cutting are.
Aus dem Stand der Technik sind insbesondere Fräser bekannt, die zur Bearbeitung von Konturen eingesetzt werden. Derartige Konturfräser bestehen aus einem Hartmetallschaft, der derart beschaffen ist, dass er eine geformte Schneide an seiner Stirnseite aufweist. Diese Schneiden können dabei radial verlaufend, beispielsweise sternförmig, angeordnet sein. Als Nachteilig bei derartig bekannten Konturfräsern wird es angesehen, dass der Fräser aus Vollhartmetall besteht, so dass die Herstellungskosten eines derartigen Fräsers sehr hoch sind. Weiter erfordert es, dass insbesondere derartige Vollhartmetallkonturfräser in entsprechenden Durchmessern mit unterschiedlichen Schneidradien vorgehalten werden müssen, so dass für jede Schneidkontur ein entsprechender Konturfräser vorzuhalten ist.From the prior art are in particular milling cutter known that are used for machining contours. such contour milling consist of a hard metal shaft, which is designed in such a way that it has a shaped cutting edge on its face. This Can cut be arranged radially, for example star-shaped. As A disadvantage of such known contour milling cutters is that the router consists of solid carbide, so that the manufacturing costs of a such router are very high. It also requires that in particular such Solid carbide contour milling in corresponding diameters with different cutting radii must be kept available so for a corresponding contour cutter must be available for each cutting contour.
Hieraus ergibt sich die der Erfindung zugrunde liegende Aufgabe. einen Konturfräser derart weiter zu bilden, der hinsichtlich seiner Kostenstruktur wesentlich günstiger ausfällt, wobei dessen Einsatz wesentlich flexibler ist.This results in that of the invention underlying task. to further develop a contour milling cutter in such a way which is much cheaper in terms of its cost structure fails, its use is much more flexible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der die Schneiden bildende Bereich mittels einer lösbaren Formschlussverbindung mit dem Schaft zusammenwirkt. Aufgrund dieser Ausbildung wird erreicht, dass der verschleißanfällige Stirnbereich des Konturfräsers auswechselbar gehalten ist. Weiter wird durch diese Ausbildung erreicht, dass unterschiedliche Schneiddurchmesser mit unterschiedlichen Radien an einem Schaft angesetzt werden können, so dass letztendlich nur ein Schaft benötigt wird. Dadurch können kostenintensive Umrüstzeiten an den Fräsautomaten eingespart werden.This object is achieved according to the invention solved, that the area forming the cutting edges by means of a releasable positive connection the shaft cooperates. Because of this training it is achieved that the wear-prone forehead area of the contour cutter is held interchangeably. Furthermore, through this training, that different cutting diameters with different radii can be attached to a shaft, so that ultimately only one shaft needed becomes. This allows costly changeover times on the milling machines be saved.
In Weiterbildung der Erfindung weist der Schneidbereich eine zentrale Öffnung zu einer Halteschraube auf. Die Halteschraube greift dabei in den Schaftbereich ein, so dass in Verbindung mit der Formschlussverbindung auch eine Halteverbindung gegeben ist. Dabei nehmen die radial verlaufenden Schneiden eine gewölbte Kontur ein. Denkbar für die Form der Schneiden sind auch gerade Formen. V-Formen oder dergleichen. Um insbesondere den Schneidbereich zu kühlen, aber auch um den anfallenden Span abzuführen, sind vor den Schneiden radial verlaufenden Spül- oder Spanabfuhrkanäle vorgesehen.In a further development of the invention the cutting area has a central opening to a retaining screw on. The retaining screw engages in the shaft area, see above that in connection with the positive connection there is also a holding connection is. The radially running cutting edges take on a curved contour on. Possible for the shape of the cutting edges are also straight shapes. V-shapes or the like. To cool the cutting area in particular, but also around the area to be cut To remove chip radial flushing or chip removal channels are provided in front of the cutting edges.
Nach einer vorteilhaften Weiterbildung der Erfindung besteht die Formschlussverbindung aus einer Tasche am stirnseitigen Ende des Schaftes, in die in Formschluss ein Unterseitenbereich der Schneide greift. Hierbei nimmt insbesondere der Formschluss die Form einer Polygonverbindung ein, dabei kann der Formschluss auch die Form eines Dreiecks, eines Vierecks oder eines Zylinders oder dergleichen einnehmen.After an advantageous further education the invention, the positive connection consists of a pocket at the front end of the shaft, in the form of a bottom area the cutting edge grips. In particular, the form fit takes place the shape of a polygon connection, the form fit also the shape of a triangle, a square or a cylinder or the like.
Die Formschlussverbindung kann dabei eine leichte Konizität aufweisen, so dass durch die Halteschraube eine Pressverbindung in der Tasche des Schaftes hervorgerufen wird.The positive connection can a slight taper have, so that a press connection by the retaining screw is caused in the pocket of the shaft.
