ABSTRACT:
A direct-acting table mechanism in which tables are driven without any contact by use of a hydrostatic fluid for thrust-transmitting the tables in their sliding direction. The tables are hydrostatically supported on hydrostatic guides on a bed, and differential pressures are supplied to the hydrostatically supporting portions to control the attitude of the tables. This table mechanism is of high degree of accuracy uninfluenced by errors in the feed screw system, high rigidity and thus permits highly stable fine feed.
