A table device including a first member; a second member; a first guide device guiding the second member such that the second member is moved in a direction parallel to a first axis by movement of the first member; a table supported by the second member; a third member connected to at least a part of the table; a bearing member forming a gas bearing between the bearing member and the third member with a gas supplied between the bearing member and the third member, and movably supporting the third member in the direction parallel to the first axis; and a support device including a parallel pin that is arranged such that the parallel pin becomes parallel to the first axis, and connects the second member and the table, and supporting the table. The table is supported by the second member through the support device.

A jig for adapting a cutting machine to cut a work piece along a radius. The jig includes a base for mounting the jig to the cutting machine. A bridge is pivotally mounted to the base. The bridge is further configured to receive the work piece. A slide is disposed beneath the bridge, where the slide is configured to selectively engage the bridge at a desired position along a length of the bridge. The slide mounts to the table at a variable position along a length of the table, and the slide is further configured to move the bridge relative to the base in a generally arcuate manner.

A workpiece change for use in a machine tool that comprises a tool spindle for clamping tools for machining workpieces, comprises two wheels arranged parallel to one another and rotatable about an axis of rotation into at least two prominent angular positions. Two swivel tables for clamping workpieces are arranged between the wheels and are each mounted on the wheels to swivel about a swivel axis which runs parallel to the axis of rotation. In each prominent angular position, one of the swivel tables is located in its working position in which clamped workpieces can be machined with the tools. Both wheels are supported at their rim.

A mobile fluid transfer system. The system includes a fluid evacuation system, a fluid refill system, a sensing system and a control system. The fluid evacuation system comprises a first fluid storage container. The fluid refill system comprises a second fluid storage container. The sensing system is coupled to the fluid evacuation system and the fluid refill system. The control system is coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control system is configured to determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.
