COORDINATE TABLE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: coordinate table is provided with hydrostatic guides of cylindrical shape, each of them being fitted with two hydrostatic supports placed at base distance from each other. Each support incorporates two high-pressure chambers placed in vertical plane and two high-pressure chambers positioned in horizontal plane. Each chamber is hydraulic joined to pump station through magneto-rheological choke. Low-pressure chambers are placed around each high-pressure chamber. For increase of positioning precision, reliability and speed of action hydrostatic guides of cylindrical shape are sealed by means of tightening elements made in the form of flexible thin-walled shells in the form of bodies of revolution mounted for rolling between hydrostatic guide of cylindrical shape and corresponding carriage. Magneto-rheological chokes are manufactured in the form of magnetic field inductor. EFFECT: increased positioning precision, reliability and speed of action. 8 cl, 18 dwg
