Abstract
Die Erfindung betrifft eine mehrschichtige kreisscheibenförmige Schleifscheibe 1 mit mindestens drei im wesentlichen planen Schichten 2, 3 und 4, die eine innere Schicht 2 und zwei unmittelbar an die innere Schicht angrenzende äußere Schichten 3 und 4 umfassen, von denen wenigstens die innere Schicht einen Anteil an Diamantschleifkorn aufweist, wobei der Anteil an Diamant in dem Schleifkorn in der inneren Schicht größer ist als in den äußeren Schichten.The invention relates to a multi-layer circular disk-shaped grinding wheel 1 with at least three essentially planar layers 2, 3 and 4, which comprise an inner layer 2 and two outer layers 3 and 4 directly adjoining the inner layer, of which at least the inner layer has a proportion of Having diamond abrasive grain, the proportion of diamond in the abrasive grain in the inner layer is greater than in the outer layers.
Description
Die vorliegende Erfindung betrifft eine Schleifscheibe mit den Merkmalen des Oberbegriffs des Anspruchs 1 sowie eine Verwendung einer derartigen Schleifscheibe.The present invention relates to a grinding wheel with the features of the preamble of
Schleifscheiben, die aus einer einzigen homogenen Schicht abrasiven Materials bestehen, sind allgemein bekannt. Beispielsweise zeigt das Dokument
Mehrschichtige Schleifscheiben sind ebenfalls bekannt, beispielsweise aus dem Dokument
Schleifscheiben mit einer Matrix, die homogen oder in allen Schichten gleich viel Diamantschleifkorn enthält, sind kostspielig in der Fertigung. Eine dreischichtige Schleifscheibe mit einer mittleren oder inneren Schicht, die frei von Diamantschleifkorn ist, ist nicht zum Schleifen von keramischen Kugeln geeignet.Grinding wheels with a matrix that is homogeneous or contains the same amount of diamond abrasive grain in all layers are costly to manufacture. A three-layer grinding wheel with a middle or inner layer that is free of diamond abrasive grain is not suitable for grinding ceramic balls.
Es ist deshalb Aufgabe der vorliegenden Erfindung, eine mindestens dreischichtige Schleifscheibe zu schaffen, die in der Fertigung gegenüber dem Stand der Technik preiswerter ist und die insbesondere zum Schleifen von keramischen Kugeln geeignet ist.It is therefore the object of the present invention to create a grinding wheel with at least three layers, which is cheaper to manufacture than the prior art and which is particularly suitable for grinding ceramic balls.
Diese Aufgaben werden von einer Schleifscheibe mit den Merkmalen des Anspruchs 1 und durch eine Verwendung einer solchen Schleifscheibe gelöst.These objects are achieved by a grinding wheel with the features of
Weil die Schleifscheibe mit einer inneren oder mittleren Schicht und wenigstens zwei äußeren Schichten versehen ist und die innere Schicht einen höheren Anteil an Diamant im Schleifkorn aufweist als die beiden unmittelbar an die innere Schicht angrenzenden äußeren Schichten, ist eine Einsparung von Diamantschleifkorn gegenüber homogen aufgebauten Schleifscheiben oder solchen Schleifscheiben, deren Schichten sich nur durch die Korngröße, nicht aber durch den Gehalt an Diamant unterscheiden, möglich. Außerdem kann eine solche Schleifscheibe vorteilhaft zum Schleifen von keramischen Kugeln eingesetzt werden, da sich in der mit den Kugeln in Kontakt kommenden äußeren Schicht schnell die erforderlichen Führungsrillen ausbilden und die innere Schicht vorwiegend oder ausschließlich abrasiv wirken muss, also den eigentlichen Schleifvorgang bewirkt.Because the grinding wheel is provided with an inner or middle layer and at least two outer layers and the inner layer has a higher proportion of diamond in the abrasive grain than the two outer layers immediately adjacent to the inner layer, there is a saving in diamond abrasive grain compared to homogeneously structured grinding wheels or such grinding wheels, the layers of which differ only in the grain size, but not in the diamond content, are possible. In addition, such a grinding wheel can be used advantageously for grinding ceramic balls, since the necessary guide grooves quickly form in the outer layer that comes into contact with the balls and the inner layer must have a predominantly or exclusively abrasive effect, i.e. the actual grinding process.
Vorteilhaft ist zumindest die innere Schicht mit Schleifkorn in Kunstharzbindung ausgeführt. Es ist weiter von Vorteil, wenn die beiden unmittelbar jeweils an einer Planseite der inneren Schicht an die innere Schicht angrenzenden äußeren Schichten das gleiche Schleifkorn aufweisen, und insbesondere dass diese beiden äußeren Schichten die gleiche Dicke in Axialrichtung aufweisen.At least the inner layer is advantageously made with abrasive grain in a synthetic resin bond. It is also advantageous if the two outer layers directly adjoining the inner layer on a plane side of the inner layer each have the same abrasive grain, and in particular that these two outer layers have the same thickness in the axial direction.
Bei ihrer Verwendung zum Kugelschleifen wird die neue Schleifscheibe vorzugsweise mit einer äußeren Planseite auf eine metallische Trägerplatte geklebt. Die unmittelbar auf der Trägerplatte aufliegende äußere Schicht wir dann nicht zu Schleif- oder Führungszwecken beim Kugelschleifen genutzt. Es hat sich aber als vorteilhaft erwiesen, diese der baugleich ausgeführten anderen äußeren Schicht gegenüber liegende Schicht vorzusehen, da sich dadurch ein Verzug der gesamten Schleifscheibe und insbesondere der inneren Schicht während der Fertigung minimieren lässt.When used for ball grinding, the new grinding wheel is preferably glued to a metal carrier plate with an outer flat side. The outer layer lying directly on the carrier plate is then not used for grinding or guiding purposes during ball grinding. However, it has proven to be advantageous to provide this layer opposite the structurally identical other outer layer, since this allows distortion of the entire grinding wheel and in particular of the inner layer to be minimized during manufacture.
