CONSTRUCTION AND OPTIMIZATION OF FORMING CIRCUITS ON THE BASIS OF HYDRAULIC CONNECTIONS ON MACHINES WITH COMPLEX MOVEMENTS SHAPING Vanin VA , D.Sc.

Student, e-mail: dezha.anton@yandex.ru Tambov State Technical University, 116 Sovetskaya str., Tambov, 392000, Russian Federation Abstract This article shows the possibility of using the hydraulic connections on the basis of step hydraulic drive in the internal circuits of gear-cutting machines. The machine tools instead of mechanical chains used aggregate-modular technology. The use of this technology will allow: to create a more rational layout of the machine; to effect the unification of drives as a whole; improve manufacturability design the internal circuits and the machine itself; reduce metal machine; reduce the accumulated error items, as a hydraulic connection error is independent of the distance between the master device and the executive stepper hydraulic motor, and will be determined by the finite accuracy of chain links, precision hydraulic stepper drive tool and workpiece.
