Abstract: A machine tool with active damping is provided, having a ram with longitudinal walls wherein vibrations are produced during machining according to at least a main bending direction (D1, D2) of the ram, a head that is arranged at one free end of the ram, actuation means for actuating the head which are arranged on one of the longitudinal walls of the ram, and damping means configured to generate at least a force (F1, F2) in the main bending direction (D1, D2) of the ram, wherein the damping means are arranged in a partial cross section of the longitudinal wall of the ram wherein the actuation means are arranged, the partial cross section being located between the actuation means and the free end of the ram on which the head is arranged.

Abstract: The present invention relates to a retractable shank for machine tools and use of said retractable shank in machine tools made up of a shank core, on which there is arranged at least one front unit formed by a rotating bush which is associated, by means of bearings, with respect to a fixed portion of the machine structure, this front unit being removable by means of outwards extraction or inwards movement, leaving a space in which the rear rotating shaft of the headstock can be housed.

Abstract: The present invention relates to a compensation system for compensating for the drop of the ram in a machine tool, comprising a vertical translation carriage (1) incorporating the application ram, at least one and preferably two perforated plates (2) being arranged on said carriage (1), on each of which there is incorporated a fixed sliding block (3) and movable sliding blocks (4), which blocks are linked with a guide for the transverse movement of the ram, such that the drop of the ram is compensated for by means of the controlled bending of the plates (2).
