PURPOSE: A clamping device for tables of a machining center is provided to obtain the large clamp force as the clamp force is applied to both sides of a clamp disk. CONSTITUTION: A clamping device for tables of a machining center comprises a table (1), a shaft (2), a rotator holder (3), a rotator (4), a stator (5), a stator holder (6), a bearing (7), a clamp disk (8), a spacer, an expansion cover, a support, and a lower cover. The clamp disk is fixed to the lower part of the shaft by using a bolt. The spacer is installed on the outer surface of the clamp disk. The expansion cover is each installed on upper and lower surface of the clamp disk and the spacer having a gap. The support is connected to the expansion cover and forms a hydraulic chamber. The lower cover is installed at the lower part of the support, the rotator, and the stator by using a bolt.
