Description

The new designs of precision guided hydraulic supports, that can improve specific speed, accuracy and energy efficiency of high-speed spindle knots have been developed. Based on the created mathematical model of trajectories spindle were identified and experimentally confirmed regularities of influence on the accuracy parameters of spindle knot the geometric form deviations, thermal deformations of support surfaces of hydraulic bearings, character of the technological components of loading, operating parameters of hydraulic supports. The regularities of the pressure distribution on supporting surfaces of high-speed guided hydraulic supports taking into account the turbulence and compressibility of fluid flow were determined. The method of numerical simulation performance precision of high-speed spindle knots was developed and the results of their calculation were presented. Were installed and analyzed rational operational parameters of the guided hydraulic supports of high-speed spindle knots machine tool. To increase productivity and accuracy machining on machine tools scientifically based method of choice rational operating and design parameters of the guided hydraulic supports have been developed. The effective technological means to improve the accuracy of the support surfaces of hydraulic bearings guided type have been developed.
