Abstract
Ein Nachlaufsetzstock (10) für Schleifmaschinen (5) zum Rund schleifen von Werkstücken (34) mittels einer radial zur Werk stückachse (14) zustellbaren Schleifscheibe (35), weist minde stens zwei Backen (21, 31) auf, die in zwei umfangswinkelver setzten Punkten (6, 7) an eine Oberfläche (41) des Werkstücks (14) anlegbar sind, und weist ferner Antriebsmittel (29, 27) zum Zustellen der Backen (21, 31) synchron mit der durch das Rundschleifen verursachten Minderung des Werkstückdurchmessers auf. Dabei werden beide Backen (21, 31) linear zugestellt, wobei die Richtungen der Zustellung gegenläufig sind und geneigt zu Tangenten (42, 44) verlaufen, die in den Punkten (6, 7) an die Oberfläche (41) gelegt sind. A caster set (10) for grinding machines (5) for the round Grinding workpieces (34) radially to the work piece axis (14) adjustable grinding wheel (35), has min at least two jaws (21, 31), which in two circumferential angle ver set points (6, 7) on a surface (41) of the workpiece (14) can be put on, and furthermore has drive means (29, 27) to feed the jaws (21, 31) in synchronism with that by the Cylindrical grinding causes a reduction in the workpiece diameter on. Both jaws (21, 31) are fed in linearly, the directions of delivery are opposite and inclined to tangents (42, 44) that run in points (6, 7) the surface (41) are laid.
