摘要

This paper introduces a system to increase safety in the operation of the hydraulic units intended for clamping the circular semi-finished products in the case of centre and vertical lathes. It presents the basic diagram, the mathematical models of computation, the results of simulations made in dynamic mode and the practical achievements too. Using this hydraulic system allows decreasing the risk of unclamping the semi-finished products during machining. One of the main elements of those systems is the gas-loaded accumulator. It is the element which assures the necessary energy after the pressure source (the pump) stops.
