ABSTRACT:
The subject of the invention is an adjustable guide for machine parts of machine tools with guide shoes (15) in which provision is made for circulation of roller bodies (18) in combination with a sliding surface (17). Each guide shoe has pre-stressing and adjusting means (23) acting multiaxially. In order to avoid refinishing the guides that are secured to the fixed machine part (1), according to the invention guide rails (3) with fine-machined sliding surfaces (5, 6) are provided on the moveable machine part (2). Stands (7 to 10), having in their facing sides at least one cut-out (14) whose form corresponds to that of the guide rails (3, 4), are rigidly secured to the fixed machine part (1). One of the guide shoes (15) and its adjusting means is arranged in each cut-out side surface.
