SYSTEM OF VARIABLE HYDROSTATIC GUIDEWAY FOR VERTICAL LATHES AND A VERTICAL LATHE THAT INCLUDES SAID GUIDEWAY

摘要

The present invention relates to a variable hydrostatic track system for a vertical lathe comprising a plurality of sectors (4) arranged between a circumference (1b) of a circular base (1) and a central opening (1a) Comprises an upper housing (4a) with a hydraulic oil outlet to form a film between the rotating chuck (3) and the sector (4) when the injected hydraulic oil overflows; A positioning mechanism including a plurality of hydraulic cylinders 5 fixed to the annular base 1 in the radial direction between the central opening 1a and the sector 4 and a positioning mechanism including a rod of each hydraulic cylinder 5, ) And a piston (5j); And Each sector being guided to the radial guiding element so that the sector 4 is movable between an inner radial position and an outer radial position due to the operation 5 of the hydraulic cylinder.
