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.

According to the present invention, the operating rate of a machine tool can be increased. Solution is made by a machine tool including a processing chamber surrounded by cover walls to perform processing of a workpiece to be processed, an equerre a part of which is arranged inside the processing chamber, the equerre fixing the workpiece, an opening arranged at a part of the cover walls for access to an inside of the processing chamber, and shutter doors movable between open positions where opening of the opening is performed so that the inside of the processing chamber communicates with an outside of the processing chamber, and closed positions where closing of the opening is performed so that the inside of the processing chamber is isolated from the outside of the processing chamber.

A support structure includes: a support frame as a shaft support member for supporting two shafts; a bush provided on each of the two shafts in a slidable manner; a cover support member connected to the multiple bushes and configured to support the cover; a first connection member for connecting one end of each of the two shafts to the support frame in a manner that the relative position between the shaft and the support frame will not change; and a second connection member for connecting the other end of each of the two shafts to the support frame in a manner that the relative position between the shaft and the support frame can change.

Provided is a machine tool having increased stiffness. A machine tool of one embodiment is provided with: a base provided on an installation face of a bed and including a first installation portion on which a guiding rail for guiding a saddle in a first direction is installed, and a second installation portion provided on one end side of the guiding rail and having a column installed thereon; and a flow path which is provided on the installation face of the bed and which drains a liquid dripping from the first installation portion toward the second installation portion via an outer side of a lateral wall of the first installation portion in a second direction. The second installation portion includes a protruding portion that protrudes beyond the lateral wall of the first installation portion in the second direction. The protruding portion has formed therein a through hole through which the flow path passes.

A sliding table includes a sliding seat having a seat body made from a first material and disposed between two main rigid rails parallel with each other. The seat body has two opposite rail recesses opening toward the main rigid rails, and two inner cyclic track holes disposed between the rail recesses. Two seat body rigid rails made from a second material harder than the first material are fixed in the rail recesses to confront the main rigid rails. Two roller belt modules are arranged in two cyclic track members overmolded to the seat body. When the seat body moves along the main rigid rails, each roller belt module circulates along one of the cyclic track members.

The subject disclosure relates to a machine apparatus. The machine apparatus may perform work on one or more work pieces. The machine apparatus may be augmented or reconfigured to work on a plurality of different work pieces in specific and unique configurations.
