Abstract: In this paper a type of retrofitting of the hydraulic installation from a heavy vertical lathe is presented. This way the lathe can be transformed in a CNC machine tool with good performance data: increasing working productivity by increasing the feed speed and the position speed of the movable assemblies. The speed of the quick positioning of the ram increases from 2.500 mm/min to 10.000 mm/min. The theoretical researches consist in mathematical modelling of the balancing installation of a movable assembly and in the optimization of this structure. The designed hydraulic installation is adjusted to a vertical lathe type SC 27 CNC, built in Romania.
