Embodiment Construction

[0028] , the machine tool shown in the various views of FIG. 1 is implemented in a gantry configuration and includes a program control unit (not shown) as well as eg a tool changer and other additional units. The machine frame 1 is preferably realized in one-piece construction in order to achieve the required high rigidity. The two side walls 2 , 3 extend parallel to the Y coordinate axis and carry on their top sides horizontal guide rails 4 , 5 as part of a linear guide for the transverse slide 6 , which can be accessed via guide shoes 7 , 8 The transverse slide 6 is guided in a displaced manner on the guide rails 4 , 5 . An electric motor comprising a shaft drive or a linear motor is used as the drive for the displacement movement of the transverse slide 6 forming a crosshead spanning the two side walls 2 , 3 . On the face of the transverse slide 6 , the slide 11 is guided in two vertically spaced guide rails 9 , 10 by means of a motorized drive unit 12 so as to be displace...

Abstract

The invention relates to a machine tool comprising frame (1) which has rigid side walls (2, 3) with linear guides (4, 5) on the top; compound slides (6, 11) which is movable and situated in or on the linear guides (4, 5) of the side walls, and which guides a processing unit (14) with a spindle head (15) at a front side so as to move the processing unit (14) vertically; and workpiece holding units (24-28) which are arranged in a gap between the side walls and may include a workbench (28) or a workpiece clamping device. One side wall (3) at the front side is shorter than the other side wall (2) for forming an enlarged access to a working space of the machine tool. The linear guides (4, 5) on the side walls (2, 3) of a machine frame (1) are aligned under an acute angle to a vertical center plane of the machine frame (1).

Description

technical field [0001] The invention relates to a machine tool comprising: a frame with dimensionally rigid side walls containing horizontal linear guides on the top side; moving in the linear guides of the side walls, guiding the processing unit including the shaft head in front of the composite slide so as to make it vertically displaceable; and the workpiece mounting unit, which is arranged in the space between the side walls , the workpiece mounting unit may have a workpiece table or a workpiece clamping device. Background technique [0002] Machine tools of this type comprising two dimensionally rigid parallel side walls, a transverse slide displaceable on guides on the top surfaces of the side walls, and a front machining unit that can be equipped with cutting tools are so-called gantry machines . Usually, in machines of this type, a crosshead is formed by a transverse slide moving on the Y axis on parallel rails on the two side walls and supports a longitudinal slid...
