Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Abrichten von Schleifscheiben mit profilierter Arbeitsfläche mittels einer Abrichtrolle, bei dem man Schleifscheibe und Abrichtrolle, deren Oberfläche mit Material von höherer Härte als das der abzurichtenden Schleifscheibe belegt ist, mit gleicher Umfangsgeschwindigkeit umlaufen läßt und dabei mit hohem Druck zusammenpreßt. Es ist die Aufgabe der Erfindung, mit einfachen Mitteln eine Möglichkeit zu schaffen, den Abrieb beim eingangs genannten Verfahren des Crushens durch unterschiedliche Oberflächengeschwindigkeiten zwischen Schleifscheibe und Abrichtrolle zu vermeiden und dadurch lange Standzeiten des Abrichtwerkzeuges zu erreichen. Die Erfindung besteht darin, daß man als Abrichtrolle eine kreisrunde ebene Hartmetallscheibe verwendet, deren eine Stirnseite mit Diamantmaterial eben belegt, daß man Schleifscheibe und Abrichtrolle derart zueinan-der anstellt, daß zwischen Schleifscheibe und Abrichtrolle lediglich eine nahezu punktförmige Berührung stattfindet und daß man den Anpreßdruck zwischen Schleifscheibe und Abrichtrolle so hoch wählt, daß am Berührungspunkt die Bindemittelbrücken zwischen den einzelnen Schleifkörpern der Schleifscheibe zerbrechen.

Figure 00000001
The invention relates to a method and a device for dressing grinding wheels with a profiled working surface by means of a dressing roller, in which the grinding wheel and the dressing roller, the surface of which is coated with material of higher hardness than that of the grinding wheel to be dressed, can run at the same peripheral speed and at the same time with high speed Pressure compresses. It is the object of the invention to provide a simple means of avoiding the abrasion in the above-mentioned method of crushing by different surface speeds between the grinding wheel and the dressing roller and thereby achieving long service lives of the dressing tool. The invention consists in that a circular flat hard metal disc is used as the dressing roller, one end face of which is coated with diamond material, that the grinding wheel and the dressing roller are adjusted so that only an almost punctiform contact takes place between the grinding wheel and the dressing roller and that the contact pressure is applied choose between the grinding wheel and the dressing roller so high that the bonding agent bridges between the individual grinding wheels of the grinding wheel break at the point of contact.
