ABSTRACT:
In order to improve a machine tool for machining a workpiece by a relative movement between the workpiece and a tool, comprising a first receiving device for the workpiece or the tool, a compound slide system with a second receiving device for the tool or the workpiece and comprising a drive device for moving the second receiving device in relation to the first receiving device, which drive device acts at least two spaced-apart points of application by at least three drive struts extending parallel to at least two different directions and each with a pivot joint, and with which drive device the at least two points of application can be positioned by means of the at least three drive struts, in such a way that exact positioning of the second slide element can be achieved by structural measures, it is proposed that four drive struts of invariant length, each with a pivot joint, act on the slide element, each of which struts is pivotally connected to a guiding slide, which is guided in a linearly movable manner transversely in relation to the longitudinal direction of the respective drive struts, and a maximum of two of which drive struts run parallel to one another.
