Improvements introduced in boring machines, essentially characterized in that the fixation of each of the moving parts is achieved by actuating a double-acting hydraulic cylinder, since at each of its ends a connecting rod is articulated; this rod acts on a rod which when screwed on a support, pushes a shoe friction on the guide or bed, therefore immobilizes the moving part against its corresponding guide; for the locking of the mandrel it has a hydraulic cylinder of simple effect, which by means of a lever gags the back support of this against the tail of the head.
