Abstract

Die Erfindung betrifft eine Schleifwalze (6) für eine Keramikschleifmaschine (1) mit einem um eine Rotationsachse (44) rotierenden zylindrischen Schleifwalzenkörper (63) zum Haltern eines abnehmbaren Schleifbandes (8).The invention relates to a grinding roller (6) for a ceramic grinding machine (1) with a cylindrical grinding roller body (63) rotating about an axis of rotation (44) for holding a removable grinding belt (8).

Um bei einfacher Handhabung eine robuste und zuverlässige Schleifwalze (6) zu erhalten, wird vorgeschlagen, dass der Schleifwalzenkörper (63) an seiner Zylindermantelfläche (64) eine elastische Schleifbandauflage (65) aufweist und über Spannmittel (62) derart axial komprimierbar ist, dass beim axialen Komprimieren die elastische Schleifbandauflage (65) in radialer Richtung beaufschlagt wird um deren Außendurchmesser zu vergrößern und dadurch das Schleifband abnehmbar zu haltern.

Figure imgaf001
In order to obtain a robust and reliable grinding roller (6) with simple handling, it is proposed that the grinding roller body (63) has an elastic grinding belt support (65) on its cylindrical surface (64) and can be axially compressed by means of tensioning means (62) in such a way that when axial compression, the elastic grinding belt support (65) is applied in the radial direction in order to enlarge its outer diameter and thereby to hold the grinding belt in a detachable manner.
