Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Fräsen, insbesondere zum Rundfräsen eines aus abgekürzten und abgeschrägten Dielen zusammengesetzten Schild für eine Haspel für Kabel und dergleichen, wobei das Schild auf einem Dorn oder einem Drehtisch wird angebracht und mittels - wenigstens eines, auf dem Schild angreifenden Reibungsrad wird rundgedreht, während dabei mit einem oder mehreren zerspanenden . Werkzeugen den Umfang des Schildes wird rundgefräst und/oder eine Nute oder Rille in dem Schild wird eingefräst..The invention relates to a method and a device for milling, in particular for round milling a shield composed of abbreviated and chamfered planks for a reel for cables and the like, the shield being attached to a mandrel or a rotary table and by means of - at least one on the shield attacking friction wheel is turned while doing so with one or more cutting. The circumference of the shield is milled round and / or a groove or groove in the shield is milled.

Nach dem bekannten Verfahren zum Rundfräsen eines Haspelschildes wird dieses abgefräst durch im algemeinen eine Vorfräse welche gefolgt wird durch eine Fertigfräse oder Abarbeitungsfräse, und von denen die Drehungsachsen.senkrecht auf der Fläche des Schildes verlaufen.
Das Abrauhen des eckig verlaufenden Umfangs des Schildes mit einer Vorfräse von der die Drehungsachse senkrecht auf die Fläche des Schildes verläuft, hat die Beschwerde, dass dort, wo die Schnittbewegung hauptsächlich gegen den Nerf des Holzes verläuft, auf unerwünschter Weise grösseren Brocken aus das Schild ausgebrochen werden.
Dieses findet bei jeder Schilddiele an wenigstens einem der beiden Enden statt, sodass das Schild ein sehr geschundenes Aussehen bekommt, und das mit dem Nachfräsen oder Abarbeitungsfräsen mit einer Fertigfräse nicht oder nur schwierig ab zu helfen ist.According to the known method for round milling a reel shield, it is milled off by generally a pre-milling cutter, which is followed by a finish milling cutter or processing milling cutter, and of which the axes of rotation run perpendicular to the surface of the shield.
The roughening of the angular circumference of the sign with a milling cutter, from which the axis of rotation runs perpendicular to the surface of the sign, has the complaint that where the cutting movement mainly runs against the nerf of the wood, larger chunks have undesirably broken out of the sign will.
This takes place at every sign board at at least one of the two ends, so that the sign gets a very battered appearance, and which cannot be remedied or only with difficulty with the milling or finishing with a finish milling machine.

Eine weitere Beschwerde des bekannten Verfahrens ist, das die Standzeit der Vorfräse relativ kurz ist.Another complaint of the known method is that the life of the roughing machine is relatively short.

Die Erfindung beabsichtigt diese Beschwerden des bekannten Verfahrens zu beseitigen.The invention intends to eliminate these complaints of the known method.

Das Verfahren nach der Erfindung ist dazu gekennzeichnet, dass das Rundfräsen wenigstens teilsweise stattfindet mit einer Vorfräse wovon die Schnittrichtung hauptsächlich senkrecht auf die Fläche des Schildes verläuft.The method according to the invention is characterized in that the round milling takes place at least partially with a pre-milling machine, of which the cutting direction is mainly perpendicular to the surface of the shield.

Dadurch dass die Schnittrichtung hauptsächlich senkrecht auf den Nerf des Holzes verläuft, wird ein ungewünschtes Spalten, wie dieses sehr wohl auftreten kann bei der Anwendung des bekannten Verfahrens, verhütet.The fact that the cutting direction is mainly perpendicular to the nerf of the wood prevents undesired splitting, as can occur when using the known method.

Zur Erzielung des notwendigen Freiwinkels an der Kopffläche der Fräse, kreuzt sich die hauptsächlich parallel an der Schildfläche verlaufende Drehungsachse der Vorfräse, nach einem folgenden Merkmal des erfindungsgemässen Verfahrens, mit der Drehungsachse des Schildes.In order to achieve the necessary clearance angle on the top surface of the milling cutter, the rotation axis of the roughing mill, which runs mainly parallel to the shield surface, crosses with the rotation axis of the shield according to a following feature of the method according to the invention.

Die Bewegungsrichtungen der Vorfräse und des Schildes können auf unterschiedlichen Weisen hinsichtlich einander verlaufen.The directions of movement of the router and the shield can run in different ways with respect to each other.

Im günstiger Weise wird, nach einem weiteren Merkmal des erfundenen Verfahrens,dass Schild durch die Vorfräse im Gleichlauf zerspant.According to a further feature of the invented method, the shield is advantageously machined in synchronism by the roughing mill.

In zweckmässigeriveise wird das Schild, nach einem Merkmal des erfundenen Verfahrens, in der Nähe der Vorfräse an der unteren Seite und entgegen der Schnittkraft gestützt.In accordance with a feature of the invented method, the shield is expediently supported near the roughing mill on the lower side and against the cutting force.

Bei einer Ausführungsform des erfundenen Verfahrens ist hinter der Vorfräse eine Fertigfräse geschaltet, und wovon die Drehungsachse hauptsächlich senkrecht auf die Schildfläche verläuft.
Dadurch dass die Schnittrichtungen der Vorfräse und der Fertigfräse hauptsächlich senkrecht auf einander verlaufen, wird eine gute Abarbeitung des Umfangrandes des Schildes bekommen.In one embodiment of the invented method, a finishing mill is connected behind the roughing mill, and of which the The axis of rotation is mainly perpendicular to the shield surface.
The fact that the cutting directions of the roughing mill and the finishing mill run mainly perpendicular to one another means that the peripheral edge of the shield is processed well.

Die Vorfräse für Anwendung des erfundenen Verfahrens und Vorrichtung kann in unterschiedlichen Weisen ausgeführt'sein.The pre-milling cutter for application of the invented method and device can be implemented in different ways.

Nach einem Merkmal der Vorrichtung nach der Erfindung ist die Vorfräse aufgebaut aus einem Paket Scheibenfräsen. Jede Scheibenfräse ist in an sich bekannter Weise.aufgebaut aus einem Scheibenförmigen Stützkörper, dass an dem Umfang versehen ist mit Zähnen, welche nach der Scheidkante zu verbreitet und bis ausserhalb des Stützkörpers auslaufen zur Bildung der gewünschten Freiwinkel.According to a feature of the device according to the invention, the roughing mill is constructed from a package of disk milling. Each disk milling machine is constructed in a manner known per se from a disk-shaped support body that is provided on the circumference with teeth that spread too far after the cutting edge and run out outside the support body to form the desired clearance angles.

Die Erfindung wird jetzt näher erläutert an hand der Zeichnung eines Ausführungsbeispiels.The invention will now be explained in more detail with reference to the drawing of an embodiment.

Wie in der Zeichnung in Draufsicht schematisch ist dargestellt, ist auf dem Dorn (1) eines unterliegenden Drehtisches ein Schild (2) angebracht, und dassmittels zwei, auf beiden Seiten auf dem Schild angreifenden Reibungsräder, wovon nur das obene Reibungsrad (3) ist dargestellt, rundgedreht werden kann, und wobei mittels der Vorfräse (4), die Fertigfräse (5) und die Walzenstirnfräse (6) respectiv der Umfangsrand des Schildes wird abgerauht und fertiggefräst und die Nut (7) in der Schildfläche eingefräst. Während des Fräsens wird das Schild in der Nähe der Vorfräse an der unteren Seite unterstützt durch ein in gestrichelte Linien angegebenen hölzernen Stützorgan.As is shown schematically in the drawing in plan view, a plate (2) is attached to the mandrel (1) of an underlying turntable, and that by means of two friction wheels acting on both sides of the plate, of which only the upper friction wheel (3) is shown , can be turned round, and by means of the roughing cutter (4), the finishing cutter (5) and the end milling cutter (6) or the peripheral edge of the shield is roughened and milled and the groove (7) milled into the shield surface.
