Abstract

In a belt grinding machine, comprising a work rest (10) and at least one grinding unit (12) with a revolving endless grinding belt (14) and a pressure beam (20) which is intended for pressing the grinding belt (14) onto the work surface (18) and has a support (24) directed essentially parallel to the work rest (10) and having bores (28) in which pressure members (30, 32) are held in a freely movable manner perpendicularly to the work rest (10) and are preloaded in such a way that they can be deflected elastically in the direction of the work rest (10), the movement of the pressure members (30, 32) being limited by a stop in the direction of the work rest (10), and the pressure members (30, 32), arranged in a matrix-shape in several rows and columns, being offset relative to one another in adjacent rows in each case in the direction of the row, the bolt-shaped pressure members (30), with their free bolt ends facing the grinding belt (14), bear directly on the rear side of the grinding belt (14). In this arrangement, the pressure members (30, 32) of one row are each offset relative to the pressure members (30, 32) of the respectively adjacent row only by a fraction of a bolt diameter. At a given bolt diameter and mutual bolt spacing, the amount of offset and the number of pressure-member rows are selected in such a way that - viewed in each plane parallel to the passage direction A of the workpiece (18) and perpendicular to the grinding plane - the grinding length is at least approximately the same. <IMAGE>
