A positioning device in a gantry-type construction, include two parallel linear guides with integrated linear drives, each of which supports an X-carriage in a manner allowing movement in an X-direction, and having a cross bar which is joined to the two X-carriages and which, with the aid of an integrated linear drive, supports a carriage in a manner allowing movement in a Y-direction perpendicular to the X-direction. In addition, the positioning device has a toolholder which is guided on the Y-carriage in a Z-direction and bears a tool for processing a workpiece located in an X-Y plane, the tool being located next to the cross bar so as to be offset in the X-direction. A force frame, disposed above the tool in the Z-direction, transfers a process force acting on the tool, to the carriages, without deforming the cross bar by a torque. |

1. A positioning device in gantry-type construction, comprising:
two parallel linear guides having integrated linear drives, each linear guide supporting a first carriage in a manner allowing movement in a first direction; a cross bar joined to the two first carriages and which, with the aid of an integrated linear drive, supports a second carriage in a manner allowing movement in a second direction perpendicular to the first direction; a toolholder guidable on the second carriage in a third direction perpendicular to the first direction and to the second direction, the toolholder adapted to hold a tool for processing a workpiece located in a plane defined by the first direction and the second direction, the tool being located next to the cross bar and offset in the first direction; and a force frame, located above the tool in the third direction, adapted to transfer a process force acting on the tool to the first carriages. |
