Claim:
1. A carrier structure of a machine tool, the carrier structure forming a guiding device for a movement unit of the machine tool and comprising: a carrying base structure that extends in a longitudinal direction of the carrier structure; and a profile carrier that is connected to the carrying base structure via laser welding, that extends in the longitudinal direction of the carrier structure, and that stiffens the carrying base structure, the profile carrier comprising: a base profile of metal; and a reinforcement member of a fiber-reinforced plastic material that reinforces the base profile, wherein the reinforcement member and the base profile are connected to each other along a profile wall of the base profile, wherein the reinforcement member and the base profile are connected to each other by at least one wall-side positive-locking element that is provided on the profile wall of the base profile and that extends in a transverse direction of the profile wall, and wherein the at least one wall-side positive-locking element and the fiber-reinforced plastic material of the reinforcement member engage one inside of the other in the transverse direction of the profile wall with a positive-locking connection between the fiber-reinforced plastic material of the reinforcement member and the base profile formed, the positive-locking connection being effective substantially parallel to the profile wall.
