FIELD: metal working industry branch, lathes.
SUBSTANCE: apparatus includes pickups for detecting drift of spindle axis and tail spindle axis in shaping plane and member for shifting tail spindle axis according to drift of spindle axis. In order to enhance working accuracy, said member is in the form of hydraulic cylinder mounted in housing of machine tool and having rod resting upon tail spindle. Apparatus is provided with two digital devices for indicating value of drift of spindle axis and tail spindle axis in shaping plane. Said devices are connected with above mentioned two pickups. Apparatus also includes valve for regulating oil pressure in hydraulic cylinder. It is possible to supply oil pressure to hydraulic cylinder from hydraulic station of machine tool.
EFFECT: enhanced accuracy of working.
