Abstract: A method and a device for connecting objects by means of a connecting element which can be plasticised by heat, on which connecting element a rivet head is formed by means of a heatable cap having a small-volume configuration. The cap is heated by a heating element which is moveable together with it in the direction of the connecting element and is configured as a large-volume heat store. The heating element is separated from the cap after forming the rivet head but before withdrawal of the cap from the rivet head, in order to enable rapid cooling of the rivet head.

Abstract: A machine tool is described, in particular a grinding machine, with a tool storage device. The tool storage device contains an outer magazine wheel (34) and an inner magazine wheel (58), which are independently concentrically rotatable in a controlled manner. The outer magazine wheel (34) preferably holds grinding tools (56), while the inner magazine wheel (58) preferably holds grinding wheel protectors (68). The grinding tool (56) and the grinding wheel protector (68) are removed from the tool storage device and are returned to the latter by the tool spindle (30). The grinding tools (56) and grinding wheel protectors (68) can be exchanged independently in arbitrary combinations and possibly also simultaneously.

Abstract: A tool magazine is located adjacent to the work space of a machine tool. The tool magazine has a magazine wheel (34) that is rotatable in a controlled manner about a vertical axis and exhibits tool holders (50) on its periphery, in which tools can be held with the tool axis directed radially with respect to the magazine wheel (34) and can be removed with their shafts directed toward the inside of the magazine wheel (34). The horizontally aligned tool spindle is displaceable along the horizontal Y-axis and along the vertical Z-axis and can be lowered into the magazine wheel (34) from above, in order to directly remove the tools from the inside of the magazine wheel (34).

Abstract: A machine tool and more particularly a drilling and/or milling machine, which has a machine stand, on which a slide arrangement, which runs on guide rails and is motor driven, is able to be moved in either direction of horizontal motion. On this slide arrangement a working head is arranged to receive rotary tools. Underneath the working head in a working area a power driven machining table runs along vertical guide rails for the performance of vertical working movements. The working area is laterally delimited by two side walls at least partly, such side walls extending in parallelism to the longitudinal direction, the vertical guide rails for the working table being arranged on one of the side walls. This means that there is a simple design allowing for removal of shavings to the rear and accordingly a narrow form of the machine.
