The spindle drive is derived from asynchrony motor which is controlled by frequency regulator. The spindle revolutions are infinitely variable in all three ranges shifted hydraulically.
The drive is longitudinal feed – axis Z – is done by servodrive mounted directly on the ballscrew. On the longer lathes over 5000 mm the drive is through the apron which contains two pre-loaded pinions with backlash elimination, which drive a rack. The drive of cross feed – axis X – is again by servodrive directly on the cross ballscrew. The measuring of both axes is provided by rotary sensors placed on servodrives. On machines with longer distance between centres is the axis Z measured directly by of linear rule. The lubrication of gears in spindlestock, hydraulic operation of spring spindle brake and speed shifters is provided by lubrication and hydraulic unit placed on the rear side of the bed. The monitor and control board of control system is integrated into box and placed in front of the guard where are also placed two electronical hand wheels.
