Abstract: A disc tool for a processing machine for grinding and/or polishing a workpiece (W); wherein the disc tool (10A, 10B, 10B) has a carrier (20) for attachment to an output (85) of the processing machine (80); wherein a cushion element (40A, 40B, 40C) made of elastic material and a retaining wall element (41A, 41B, 41C, 41D) for retaining the cushion element (40A, 40B, 40C, 61) are arranged on the carrier (20); wherein the retaining wall element (41A, 41B, 41C, 41D) is held on the carrier (20) by means of retaining bolts (35); wherein retaining bolt passage openings (48) of the retaining wall element (41A, 41B, 41C, 41D) extending through retaining mounts (28), of the carrier (20) are accommodated along bolt sections (36) of the retaining bolts (35) extending along the bolt longitudinal axes (BL), and the retaining wall element (41A, 41B, 41C, 41D) is held between bolt heads (37) of the retaining bolts (35) and the carrier (20); and wherein an adhesive layer (50) is arranged on a side of the retaining wall elemen

Abstract: The invention relates to a guiding device 100, a system comprising a guiding device and a tool 111 for surface treatment, a method for surface treatment with the guiding device 100 and a method for retrofitting a tool 111 with the guiding device 100. The guiding device 100 comprises at least one guide element 101, one angle device 102 and one connection arrangement 130 for connecting the guiding device to the tool 111. Furthermore, a predetermined angle between the plane 180 of the at least one guide element 101 and a plane of action 110 of the connectable tool 111 is set by means of the angle device 102. The guiding device 100 is furthermore characterised in that it is switchable between at least one flexible operating state and one rigid operating state.

Abstract: The invention relates to a method for producing slots (11) in a tube wall (10), wherein a single die plate (2) provided with notches (20) is pushed into the tube (1) and punches (5) arranged in a row pierce the tube wall from the outside and in the process produce the slots (10), whereupon the die plate (2) is rotated about its longitudinal axis out of a working position and into a withdrawal position and is pulled out of the tube (1). Economical production of the slots in tubes having different cross-sectional shapes is achieved according to the invention in that during the slotting operation the tube wall (30) is gripped from the outside and held and is stabilized from the inside against two opposing support strips (25) by way of the die plate (2).
