Abstract

Die Erfindung betrifft einen Schleifteller (40) für eine Hand-Schleifmaschine (10), mit einer Antriebshalterung (33) zur drehfesten Befestigung an einem Abtrieb (14a) der Hand-Schleifmaschine (10), so dass der Schleifteller (40) durch die Schleifmaschine (10) in eine zu einer schleifenden Bearbeitung eines Werkstücks (W) geeignete Schleifbewegung antreibbar ist, wobei ein Schleiftellerkörper (57) des Schleiftellers (40) eine mit einer Haftschicht (65) versehene Bearbeitungsfläche (42) zur lösbaren Befestigung eines mit einer Gegenhaftschicht (82) versehenen, insbesondere als Schleifblatt (90) ausgestalteten und eine Abrasionsschicht (81) zu einer abrasiven Bearbeitung des Werkstücks (W) aufweisenden Schleifmittels (80) aufweist, wobei an der Bearbeitungsfläche (42) Staubluft-Einströmöffnungen (44-48) für bei der Bearbeitung des Werkstücks (W) entstehende, mit Staub beladene und durch Staubluft-Durchströmöffnungen (84-88) des Schleifmittels (80) entlang einer Hauptströmungsrichtung (H) einströmende Staubluft (S) angeordnet sind, die mit mindestens einer Staubluft-Ausströmöffnung (50) an einer von der Bearbeitungsfläche (42) abgewandten Maschinenseite (31) des Schleiftellers (40) über eine Absaugkanalanordnung (78) verbunden sind, so dass im an der Schleifmaschine (10) montierten Zustand des Schleiftellers (40) eine Absaugeinrichtung (25) der Schleifmaschine (10) in die Staubluft-Einströmöffnungen (44-48) einströmende Staubluft (S) durch die mindestens eine Staubluft-Ausströmöffnung (50) ansaugen kann. Der Schleifteller (40) weist mindestens einen Staubluftkanal (61, 63) auf, der zum Wegfördern von Staub aus der Umgebung der Abrasionsschicht (81) einen Staublufteinlass (62, 64) zwischen der Abrasionsschicht (81) des Schleifmittels (80) und der Maschinenseite (31) des Schleiftellers (40) aufweist und abseits der Abrasionsschicht (81) mit der mindestens einen Ausströmöffnung (50) in direkter Strömungsverbindung steht.
