A device for stabilizing a workpiece, in particular a thin-walled workpiece mounted in a machine tool, comprises at least one base; and a plurality of stabilizing elements. The stabilizing elements protrude away from one surface of the base, wherein the stabilizing element comprises a cylinder and a rod arranged therein and the rod can be driven hydraulically to move in the axial direction of the stabilizing element such that the rod of at least two of the stabilizing elements can be brought into contact with one surface of the workpiece.

A linear guide bearing and an associated quick-connect system are provided. The linear guide bearing includes a carriage that moves linearly along a guide rail. The carriage includes an upper surface having a groove defined therein, and a depression formed in the groove. A tool is configured to connect to the carriage in a quick-connect fashion. To do so, the tool has a spring-loaded plunger biased downward toward the carriage. As the tool is slid along the groove of the carriage, the tip of the plunger is biased to depress into the depression in the groove. To release the tool from the carriage, a force can be applied sufficient to overcome the spring-bias force to allow the tool to lift off from the carriage.

A sliding table device includes a base unit, a sliding unit and a cover plate. The sliding unit includes two rails, two sliding blocks disposed respectively and slidably on the rails and each having an oil inlet, and a sliding seat mounted co-movably on the sliding blocks. The sliding seat includes a main portion having a flow passage and an insertion hole that interconnects the flow passage and external environment, two fixed portions mounted respectively to the sliding blocks and each having a connecting passage that communicates with the flow passage, and two guiding portions formed respectively on the fixed portions and each having a guiding passage that communicates with the corresponding connecting passage and the corresponding oil inlet. The cover plate covers a portion of the main portion, and the insertion hole is not covered by the cover plate.

A composite machining machine includes a first machining head, a second machining head, a workpiece holder, a cover, and a frame. The first machining head is movable in a first region to perform additive manufacturing on the workpiece in a second region. The second machining head is movable in the second region to perform cutting on the workpiece. The workpiece holder holds the workpiece in the second region. The cover covers the first region. The frame includes two columns and a beam member coupling the columns. The cover includes a region definition member openable at least partially. The region definition member defines the second region. The first machining head is movable in a guided manner in a range between the columns. The beam member is disposed so that the predetermined range lies inside the first region, and outside and above the second region.

The present invention provides a wafer centering device for a measurement apparatus, the device comprising: a body unit; a guide unit which is installed in the body unit, has a support part for supporting a wafer, and has a through-hole and; and a displacement unit which is formed to be moved in the through-hole and has a pusher for moving the wafer on the support part.
