MOVEMENT DEVICE, PARTICULARLY FOR CUTTING TORCHES OF THE PLASMA TYPE AND THE LIKE

摘要

A movement device (1), particularly for cutting torches of the plasma type, comprising a working head (2) that can move along three Cartesian axes (3, 4, 5) which are mutually perpendicular and supports a cutting torch (7) for cutting mechanical pieces and the like. Moreover, means are comprised for the combined rotary and translational motion (9) of the cutting torch (7) with respect to the working head (2) in order to vary the inclination of the cutting flow with respect to the mechanical piece or the like being worked on; the center of instantaneous rotation of the cutting torch (7), with respect to which the means for combined rotary and translational motion (9) operate, substantially coinciding with the focal point (11) of the cutting torch (7).
