A lathe contains a drive of forming motion, which includes kinematic chains of working motion and feed motion, a support connected with a bed through a hydraulic pair “cavity of hydraulic cylinder – piston”, and in the kinematic chain of working motion a non-self-braking screw pair is installed, one of elements of which is connected with the support. The cavities of hydraulic cylinder are connected through an adjustable choke controlled by automatic system, which contains a loading sensor of the engine of working motion, a comparator and a programming unit, and an actuating mechanism. |
