<p>The invention relates to a machine tool comprising a drive motor (1) and a tightening system (8) for a tool (9), said tightening system being assigned to a working spindle (13), and comprising a system for minimal quantity lubrication having a first line (3), which is connected to a compressed air source, and a second line (4) that is connected to a lubricant source, both of these lines leading to a mixing chamber (5). Each of the number of tightening systems (8) is assigned to a revolver head (6) having a drive shaft (7), and each tightening system (8) is passed through by a mixing line (10) leading to the tool (9). When in a working position, the mixing line leads out of the mixing chamber (5), and the drive shaft (7) is arranged in a manner that enables it to be displaced relative to the mixing chamber (5) and to the first line (3) and the second line (4)..</p> |
