Abstract (en)

[origin: CA2278912A1] A belt grinding machine has a grinding belt continuously guided about at least two deflection rollers 2, a pressure shoe 3 that presses the grinding belt 1 against a workpiece 8 by a contact pressure apparatus. The belt grinding machine also has a contact pressure control that allows a contact pressure force to be set. The uniformity and reproducibility of the grinding results are improved by a detector arrangement 6, 7 that senses the adjustment of the pressure shoe 3 and an evaluation device that influences the contact pressure control as a function of the sensed adjustment of the pressure shoe 3.

Abstract (de)

Bei einer Bandschleifmaschine mit einem endlos um Umlenkrollen (2) geführten Schleifband (1), einem Druckschuh (3) zum Drücken des Schleifbandes (1) gegen ein Werkstück (8) mittels einer Andruckvorrichtung (4) und einer Andrucksteuerung, mit der eine Andruckkratt einstellbar ist, wird die Gleichmäßigkeit und Reproduzierbarkeit der Schleifergebnisse verbessert durch eine die Verstellung des Druckschuhs (3) sensierende Detektoranordnung (6, 7) und eine Auswerteeinrichtung zur Beeinflussung der Andrucksteuerung in Abhängigkeit von der sensierten Verstellung des Druckschuhs (3). <IMAGE>
