Machine tool, in particular universal milling machine, and method for operating such a machine

摘要

A machine tool (10), in particular a universal milling machine, comprises a table (12) for clamping a workpiece to be machined in a horizontal machining plane and a tool spindle (65) which is in a pivoting plane perpendicular to the machining plane on a center around the table (12) circular path between a vertical position and a horizontal position is continuously pivoted, the tool spindle (65) being fastened to an arc segment (15) which is guided in a first arc guide (14) so as to be movable on an arc. DOLLAR A In such a machine tool (10), space-saving construction with simultaneously reduced manufacturing and assembly costs and improved accessibility of the work space is achieved in that the first arc guide (14) has the shape of a circular arc section, which the table (12) only on one Encloses side.
