3415 Development of a machine table with hydrostatic water bearings for a precision surface grinding machine : Basic design of a constant-flow hydrostatic bearing

Abstract

The authors are planning to develop a grinding-machine table sustained by the constant-flow hydrostatic water bearings. In this paper, theoretical studies have been made for the basic design of hydrostatic water bearings. Effects of bearing-pad shape, land width, water-flow rate, and water viscosity on sustaining force, static stiffness and viscous damping coefficient of a machine table sustained by hydrostatic water bearings are clarified.
