PROBLEM TO BE SOLVED: To provide a device capable of simultaneously and easily grinding both the faces of a thin disk work with a high machining quality and capable of reducing the size thereof. SOLUTION: This double face grinding device comprises a pair of grinding wheels 9, a work self-rotating means supportedly self-rotating a work W on a grinding position between grinding faces 9 so that the both ground surfaces of the work W face the ground faces 9a of the pair of stones 9, the outer periphery of the work W crosses the outer periphery of the ground faces 9a, and the center of the work W is positioned in the ground faces 9a, and a work storage and retrieval means. The self-rotating means comprises a static pressure type axial supporting means for supplying fluid to both machined surfaces of the work at the portion extended to the outside from a clearance between the stones to axially support the work W by the static pressure of the fluid in the state of non-contact with each other. The storage and retrieval means feeds the work W to a grinding position where the work W is supported by the static pressure type axial supporting means in the state of non-contact with each other, and carries out the work W from the grinding position.
