Description

Die Erfindung betrifft ein Verfahren zum Abrichten von insbesondere profilierten Schleifscheiben mit Diamant oder kubisch kristallinem Bornitrid als Schleifmittel, bei dem eine Abrichtrolle und eine mit gegenüber der Schleifscheibenumfangsgeschwindigkeit unterschiedlicher Umfangsgeschwindigkeit angetriebene Abrichtshilfsrolle aus Siliziumkarbid oder Korund verwendet wird.The invention relates to a method for dressing, in particular, profiled grinding wheels with diamond or cubic crystalline boron nitride as the abrasive, in which a dressing roller and a dressing aid roller made of silicon carbide or corundum, which is driven with a peripheral speed that is different from the peripheral wheel peripheral speed, is used.

Zum Abrichten von Diamantschleifscheiben unter Anwendung einer sogenannten Crushierrolle aus Hartmetall wird diese bei relativ langsamer Umlaufgeschwindigkeit gegen die abzurichtende Schleifscheibe gedrückt, welche die gleiche Umfangsgeschwindigkeit aufweist. Bei einem bekannten Verfahren (DE-B 2534872) wird zusätzlich eine feststehende Abrichthilfe unter konstantem Druck gegen die Schleifscheibe gedrückt. Dadurch soll ein Zusetzen der Schleiffläche durch Verdichtung beim Einrollen des Profils vermieden werden, indem durch den feststehenden Abrichtstein aus der erzeugten Oberfläche der Schleifscheibe Körner, die zunächst durch das plastische Verformen eingedrückt wurden, wieder aus der Bindung herausgearbeitet werden und eine verbesserte Oberfläche erhalten wird. Dem Abrichtstein kommt damit die Aufgabe einer Reinigung der Schleifscheibenoberfläche zu.To dress diamond grinding wheels using a so-called crushing roller made of hard metal, it is pressed against the grinding wheel to be dressed at a relatively slow rotational speed, which wheel has the same peripheral speed. In a known method (DE-B 2534872) a stationary dressing aid is additionally pressed against the grinding wheel under constant pressure. This is to prevent clogging of the grinding surface due to compaction when the profile is rolled in. By means of the fixed dressing stone, grains, which were initially pressed in by the plastic deformation, are worked out of the bond again and an improved surface is obtained by the fixed dressing stone. The dressing stone therefore has the task of cleaning the grinding wheel surface.

Bei einem weiteren, aus der DE-A 2 655 533 bekannten Verfahren, das ebenfalls zum Abrichten einer Diamant- oder CBN-Schleifscheibe eine Hartmetall- bzw. Crushierrolle vorsieht, ist als Abrichthilfe eine angetriebene Abrichthilfsrolle vorgesehen. Zum Abrichten und Schärfen muss auch bei diesem Verfahren die Schleifscheibe auf eine Umfangsgeschwindigkeit von etwa 1 m/sek abgebremst werden, um Diamantkörner aus der Oberfläche der abzurichtenden Schleifscheibe herauszubrechen. Damit ist dieses Verfahren jedoch mit einem unwirtschaftlich hohem Zeitaufwand verbunden.In a further method known from DE-A 2 655 533, which likewise provides a hard metal or crushing roller for dressing a diamond or CBN grinding wheel, a driven auxiliary dressing roller is provided as the dressing aid. For dressing and sharpening, the grinding wheel must also be braked to a peripheral speed of approximately 1 m / sec in this method in order to break diamond grains out of the surface of the grinding wheel to be dressed. However, this process is associated with an uneconomically high expenditure of time.

Auch Schleifscheiben mit einem Belag aus kubisch kristallinem Bornitrid oder Diamant, die mit einer Diamantabrichtrolle abgerichtet werden, zeigen nach dem Abrichten kein ausreichendes Schleifvermögen. Das ist u.a. darauf zurückzuführen, dass beim Durchschneiden der kubisch kristallinen Körner mit Diamanten auf den Körnern Flächen erzeugt werden, zwischen denen sich keine freien Zwischenräume befinden. Um einen Kornüberstand über die Bindung hinaus zu schaffen, der für eine ausreichende Spanabfuhr beim Schleifen notwendig ist, erfolgte bisher nach einem Abrichten einer Diamantschleifscheibe mit einer Diamantabrichtrolle ein nachträgliches Schärfen der Schleifscheibe mit einem feststehenden Abrichtstein. Durch ein derartiges Schärfen lässt sich die Bindung soweit zurücksetzen, dass die einzelnen Körner der Schleifscheibe über sie hinaus vorstehen, so dass zwischen ihnen ein freier Spanraum geschaffen wird. Die Anwendung eines feststehenden Abrichtsteines zum Schärfen einer mit einer Diamantabrichtrolle abgerichteten profilierten Schleifscheibe hat sich jedoch in der Praxis als unvollkommen gezeigt. Soll nämlich beispielsweise eine Schleifscheibe mit einem Gewindeprofil versehen werden, dessen Zähne nur sehr geringe Spitzenradien aufweisen, deren Zähne sich also im Querschnitt gesehen als Spitz darstellen, so wird durch die nachträgliche Anwendung der feststehenden Abrichthilfe eine unerwünschte Abrundung der Zahnspitzen hervorgerufen, wenn die Relativgeschwindigkeit zwischen der feststehenden Abrichtshilfe und der Schleifscheibe nicht sehr gering ist. Ausserdem muss die Relativgeschwindigkeit zwischen der Schleifscheibe und dem Abrichtstein gering sein, um genügend Bindungsmaterial beim Schärfen abzutragen. Die Anwendung des feststehenden Abrichtsteines erfordert deshalb eine sehr geringe Umfangsgeschwindigkeit der Schleifscheibe, so dass der Abrichtprozess zeitaufwendig ist.Even grinding wheels with a coating of cubic crystalline boron nitride or diamond, which are dressed with a diamond dressing roller, do not show sufficient grinding capacity after dressing. Among other things, this is attributable to the fact that when the cubic crystalline grains are cut with diamonds, surfaces are created on the grains with no free spaces between them. In order to create a grain protrusion beyond the bond, which is necessary for sufficient chip removal during grinding, the grinding wheel was subsequently sharpened with a fixed dressing stone after dressing a diamond grinding wheel with a diamond dressing roller. By sharpening in this way, the bond can be reset to such an extent that the individual grains of the grinding wheel protrude beyond it, so that a free chip space is created between them. In practice, however, the use of a fixed dressing stone to sharpen a profiled grinding wheel dressed with a diamond dressing roller has proven to be imperfect. If, for example, a grinding wheel is to be provided with a thread profile, the teeth of which have only very small tip radii, i.e. whose teeth are pointed in cross-section, the subsequent use of the fixed dressing aid will undesirably round off the tooth tips if the relative speed between the fixed dressing aid and the grinding wheel is not very low. In addition, the relative speed between the grinding wheel and the dressing stone must be low in order to remove sufficient bonding material when sharpening. The use of the fixed dressing stone therefore requires a very low peripheral speed of the grinding wheel, so that the dressing process is time-consuming.

Ausgehend vom Stand der Technik gemäss DE-A 2 655 533, wonach der Oberbegriff gebildet wurde, ist es Aufgabe der Erfindung, die Wirtschaftlichkeit dieses bekannten Abrichtverfahrens zu verbessern und insbesondere dahingehend weiterzubilden, dass der Zeitbedarf für den Abrichtvorgang geringer ist.Starting from the prior art according to DE-A 2 655 533, according to which the preamble was formed, it is the object of the invention to improve the economy of this known dressing method and in particular to further develop the fact that the time required for the dressing process is less.

Nach der Erfindung ist zur Lösung dieser Aufgabe vorgesehen, dass die Abrichtrolle eine angetriebene Diamantrolle ist und die Relativgeschwindigkeit zwischen der Schleifscheibe und der Abrichthilfsrolle 0,5 bis 6 m/s beträgt. Dies ermöglicht ein Abrichten bei Einhaltung einer hohen Umlaufgeschwindigkeit der Schleifscheibe und damit auch während ihres Arbeitseinsatzes, denn wenn nur eine Relativgeschwindigkeit zwischen der Abrichthilfsrolle und der von einer Diamantabrichtrolle profilierten Schleifscheibe in der Grössenordnung von vorzugsweise 1 m/s vorliegt, so ist diese einerseits ausreichend, um einen genügenden Kornüberstand zu schaffen, und andererseits zu gering für die Gefahr der Abrundung der Diamant- bzw. Profilspitzen.According to the invention, in order to achieve this object it is provided that the dressing roller is a driven diamond roller and the relative speed between the grinding wheel and the auxiliary dressing roller is 0.5 to 6 m / s. This enables dressing while maintaining a high rotational speed of the grinding wheel and thus also during work, because if there is only a relative speed of preferably 1 m / s between the auxiliary dressing roller and the grinding wheel profiled by a diamond dressing roller, this is sufficient on the one hand, to create a sufficient grain protrusion, and on the other hand too low for the risk of rounding the diamond or profile tips.

Die Diamantabrichtrolle kann dabei eine andere Umfangsgeschwindigkeit als die Schleifscheibe aufweisen, wobei davon auszugehen ist, dass es allgemein zweckmässig ist, zum Vorprofilieren einer Schleifscheibe die Diamantabrichtrolle im Gegenlauf rotieren zu lassen, so dass also beispielsweise die Schleifscheibe und auch die Diamantabrichtrolle gegen den Uhrzeigersinn rotieren, während beim Fertigprofilieren beide Scheiben im sogenannten Gleichlauf arbeiten, wobei dann die eine im Uhrzeigersinn und die andere gegen den Uhrzeigersinn rotiert, um dadurch bereits einen gewissen Kornüberstand über die Bindung zu erzielen. Dieser Kornüberstand wird danach durch die mit geringer Relativgeschwindigkeit arbeitende Abrichthilfsrolle auf das gewünschte Mass vergrössert.The diamond dressing roller can have a different circumferential speed than the grinding wheel, it being assumed that it is generally expedient to rotate the diamond dressing roller in the opposite direction to pre-profile a grinding wheel, so that, for example, the grinding wheel and also the diamond dressing roller rotate counterclockwise, while in finished profiling both discs work in the so-called synchronism, one rotating clockwise and the other counter-clockwise in order to achieve a certain grain protrusion over the bond. This grain protrusion is then increased to the desired level by the dressing aid roller operating at a low relative speed.

Ein Ausführungsbeispiel der Erfindung ist nachstehend unter Bezugnahme auf eine Zeichnung erläutert.An embodiment of the invention is explained below with reference to a drawing.

Die in der Zeichnung wiedergegebene Schleifscheibe 1 mit einem Belag 2 aus Diamant oder kubisch kristallinen Bornitrid rotiert entsprechend dem Pfeil 3 im Uhrzeigersinn. Zum Abrichten und Profilieren der Schleifscheibe 1 ist eine drehangetriebene Diamantabrichtrolle 4 vorgesehen, die entsprechend dem Pfeil 5 entgegen dem Uhrzeigersinn rotiert und entsprechend dem Pfeil 6 zustellbar ist.The grinding shown in the drawing disc 1 with a coating 2 of diamond or cubic crystalline boron nitride rotates clockwise according to arrow 3. For dressing and profiling the grinding wheel 1, a rotary-driven diamond dressing roller 4 is provided, which rotates counterclockwise according to the arrow 5 and can be set in accordance with the arrow 6.

Eine zusätzliche, aus keramisch oder bakelitisch gebundenen Siliziumkarbid oder Korund bestehende Abrichthilfsrolle 7 rotiert entsprechend dem Pfeil 8 ebenfalls entgegen dem Uhrzeigersinn und wird entsprechend dem Pfeil 9 zugestellt. Die Abrichthilfsrolle 7 ist derart angetrieben, dass sie eine Umfangsgeschwindigkeit von 29 m/s hat, wenn die Umfangsgeschwindigkeit der Schleifscheibe 1 30 m/s beträgt, so dass die Relativgeschwindigkeit zwischen den beiden Scheiben 1 m/s beträgt. Durch diese geringe Relativgeschwindigkeit ist es möglich, beim Abrichten der Schleifscheibe 1 mittels der Diamantabrichtrolle 4 ein Herausarbeiten der einzelnen Körner über die Bindung hinaus zu erreichen und zwar sogar dann, wenn auch mit der Schleifscheibe 1 gleichzeitig ein entsprechend dem Pfeil 11 zustellbares Werkstück 10 geschliffen wird.An additional dressing aid roller 7, consisting of ceramic or Bakelitic silicon carbide or corundum, also rotates counterclockwise in accordance with arrow 8 and is delivered in accordance with arrow 9. The dressing auxiliary roller 7 is driven such that it has a peripheral speed of 29 m / s when the peripheral speed of the grinding wheel 1 is 30 m / s, so that the relative speed between the two wheels is 1 m / s. This low relative speed makes it possible, when dressing the grinding wheel 1 by means of the diamond dressing roller 4, to work out the individual grains beyond the bond, even if a workpiece 10 which can be set in accordance with the arrow 11 is also ground simultaneously with the grinding wheel 1 .
