ABSTRACT:
The control valve for a hydrostatic bearing on a machine tool slide is opened when motion is commanded along the corresponding machine tool axis to eliminate sticking at the start of motion. The valve is closed when the velocity of motion exceeds a predetermined level and is opened again when the velocity drops below the predetermined value to eliminate sticking at the end of motion. The valve is closed again when the machine tool slide arrives at its commanded position.
