盤のテーブル駆動用油圧装置。 In a surface grinding machine whose table is driven by a hydraulic cylinder that reciprocates with fluid supplied from a hydraulic pump via a directional control valve, the directional control valve is controlled by an electric signal from an amplifier to control the spool. A regulator comprising a spool-type electromagnetic proportional directional control valve whose stroke is adjusted to control the speed of the hydraulic cylinder, and which controls the hydraulic pump to a constant pump discharge flow rate by the action of fluid pressure acting on the hydraulic cylinder. A hydraulic device for driving a table of a surface grinding machine, characterized in that it is configured with a variable displacement pump equipped with a variable displacement pump.
