To improve a machine tool, comprising a machine frame, a workpiece holder arranged on the machine frame for a workpiece to be machined, a tool holder arranged on the machine frame for receiving a tool and at least one drive with a slide for executing a relative movement between the tool and the workpiece in the direction of at least one axis, such that it allows as high dynamics as possible, it is proposed that the drive comprise electric linear motors aligned parallel to the axis and spaced from one another in a transverse direction, that the slide extend between the two linear motors, and that a control be provided for simultaneously operating the linear motors for displacement of the slide.

A machine tool comprising: (a) a frame; (b) a workpiece holder on said frame for receiving a workpiece to be machined; (c) at least one slide mounted on said frame for movement with respect to said frame in the direction of at least one axis; (d) a tool holder mounted on said slide for receiving a tool for machining a workpiece; (e) a drive for moving said slide along said at least one axis, said drive including a first and second electric linear motor each aligned parallel to said at least one axis and spaced apart with at least part of said slide extending between said linear motors; (f) a control system for controlling the movement of said slide along said axis; wherein said control system comprises a first control unit for operating said first linear motor as an independent NC axis and a second control unit for operating said second linear motor as an independent NC axis whereby each motor is capable of being operated independently of the other, but simultaneously and with parallel displacement along said axis; and (g) a slide support for supporting said slide, said slide support having at least two sides and a front face having a geometric center, and wherein said motors are respectively arranged on said at least two sides of said slide support, so that transverse to the direction of said at least one axis, said motors are in outer regions of said slide and said slide support with respect to said front face center.
