Abstract
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 machine frame;
- a workpiece holder on said frame for receiving a workpiece to be machined;
- a tool holder for receiving a tool for machining said workpiece received in said workpiece holder;
- said tool holder and said workpiece being movable with respect to each other by a first drive in a direction of a first machining axis, a second drive in a direction of a second machining axis and a third drive in a direction of a third machining axis, each of said three machining axes extending transverse to said two other machining axes;
- a control unit for controlling said first, second and third drives;
- two guide carrier elements carried by said machine frame, said guide carrier elements being arranged in spaced relationship in the direction transverse to said first machining axis and extending in the direction of said first machining axis, each of said guide carrier elements carrying a first linear slide guide extending in the direction of said first axis;
- a first slide guided by said first linear slide guides for movement along said first machining axis by said first drive, at least a portion of said first slide extending between said first linear slide guides;
- said first slide carrying two second linear slide guides extending between said first linear slide guides arranged in spaced relationship in the direction of said first machining axis and extending parallel to each other in the direction of said second machining axis;
- a second slide guided by said second linear slide guides for movement along said second machining axis by said second drive, said second slide having a portion extending between said second linear slide guides, said second slide carrying said tool holder on said portion;
- and
- said tool holder being a spindle having a spindle axis extending between said second linear slide guides in direction of said third machining axis and said spindle comprises a rearward part extending through said second slide.
