In Figur 1 ist eine Rotationsschleifmaschine dargestellt. Das Schleifgerät 1 enthält den Schleifteller 2, einem durch die Antriebswelle 3 und den Schleifteller 2 verlaufenden Vakuumkanal 4 und das mittels Vakuum befestigte Schleifmaterial 5. Der Schleifteller 2 ist mit der Antriebswelle 3 und über diese mit der Antriebseinheit 7 verbunden. Das Schleifmaterial 5 ist vorzugsweise als rundes Blättchen aus Papier mit darauf befestigten Schleifkörpern ausgeführt. Es sind jedoch auch andere Formen möglich, z.B. kann es als Wellenrand ausgebildet sein. FIG. 1 shows a rotary grinding machine. The
Figur 2 zeigt eine vergrößerte schematische Schnittdarstellung des in Figur 1 enthaltenen Schleiftellers 2 entlang der Schnittlinie A-A'. Durch den Schleifteller 2 hindurch, senkrecht zur Schleifebene 8, verläuft der Vakuumkanal 4. Das Schleifmaterial 5 ist mittels Vakuum an der Unterseite des Schleiftellers 2 befestigt. Das Gewindestück 6 verbindet den Schleifteller 2 mit der in Figur 1 gezeigten Antriebswelle 3. Das Vakuum wird vorzugsweise mit Hilfe von hier nicht dargestellten Ejektoren erzeugt. Es kann aber auch mit Venturidüsen, Pumpen, Gebläse und Saugern erzeugt werden. Das Vakuum wird über ein oder mehrere Schläuche oder durch im Inneren der Maschine verlaufende Kanäle dem Schleifgerät 1 zugeführt und über den Vakuumkanal 5 zur Schleifmittelseite des Schleiftellers 2 geleitet. Durch das Vakuum wird bei am Schleifteller 2 anliegendem Schleifmaterial 5 eine Sogwirkung ausgebildet, die das Schleifmaterial 5 an den Schleifteller 2 saugt. Das Schleifmaterial 5 haftet durch die Sogwirkung am Schleifteller 2, wobei der Schleifteller 2 aus einem Material besteht, welches eine möglichst hohe Haftreibung zwischen Schleifteller 2 und Schleifmaterial 5 gewährleistet. Dadurch wird ein Verschieben des Schleifmaterials 5 auf dem Schleifteller 2 verhindert und die sichere Bearbeitung der Werkstücke ermöglicht. Der Schleifteller 2 besteht aus einem Oberteil 2.1 und einem Unterteil 2.2. Für das aus einem festen Trägermaterial bestehende Oberteil 2.1 wird vorzugsweise Kunststoff oder Metall verwendet, während das Unterteil 2.2 aus einem flexiblen Material, beispielsweise aus Neopren besteht. Es ist auch möglich, dass der Schleifteller 2 an seiner Unterseite, an der das Schleifmittel 5 anliegt, radiale kurze Schlitze aufweist, die mit der zentralen der Austrittsöffnung des Vakuumkanals verbunden sind und eine verbesserte Anlage des Schleifmittels 5 bewirken. Die Verwendung von elastischem Kunststoffmaterial für den Schleifteller 2 ermöglicht die Bearbeitung gekrümmter Werkstücke. Besonders vorteilhaft ist dabei, dass die erfindungsgemäße Ausführung auch für kleine Durchmesser und an Einhandschleifgeräten verwendbar ist. FIG. 2 shows an enlarged schematic sectional view of the
Figur 3 zeigt eine Ausführung, bei der in das Unterteil 2.2 des Schleiftellers 2 eine Einfräsung 2.2.1 eingearbeitet ist.
