KINEMATIC STRUCTURE OF MACHINE TOOLS WITH HYDRAULIC CONNECTIONS IN SHAPING THE CIRCUITS Vanin V. A. , D. Sc. (Engineering), Professor, e-mail: vanin51141@yandex.ru Kolodin A. N. , Assistant, e-mail: dekorkan@yandex.ru Rodina A. A. , Senior Lecturer, e-mail: ant.rodina1209@yandex.ru Tambov State Technical University, 106 Sovetskaya str., Tambov, 392000, Russian Federation Abstract This article discusses the possibility of using hydraulic links with hydraulic drives stepper motors in the executive bodies of machines, where the movement is strictly coordinated with each other in a certain kinematic dependencies and build these relationships in a modular fashion based on stepper hydraulic drive. The kinematic chain composed of mechanical units are designed and manufactured individually for each machine layout. Furthermore, the mechanical kinematic chains have significant disadvantages: considerable length, low stiffness and unstable, leading to reduced accuracy.
