Abstract
A workpiece support device includes: a jig, a table, a rotating shaft, a support member, a flow path connector, and a supply-side connecting portion. The jig has a main flow path to flow a fluid for machining and a sub-flow path, and fixes the workpiece. The table has a table flow path to communicate with the main flow path and is attached with the jig. The rotating shaft has a rotating shaft flow path to communicate with the table flow path, and is fixed to the table. The support member rotatably supports the rotating shaft. The flow path connector connects the rotating shaft flow path with a fluid-supply path to communicate with a fluid-supply side so as to relatively rotate with each other about an axis of the rotating shaft. The supply-side connecting portion moves relative to the jig to communicate with and block off the sub-flow path.
