A jig apparatus includes holding members on which an object to be processed is placed, which members are supported so that they are able to move in a vertical direction. The jig apparatus also includes control unit that controls positions in the vertical direction of the holding members. Control unit causes second holding members, which are selected from among holding members around first holding members on which the object is placed, to be moved to a place in the vertical direction, and to cause the first and second holding members to cooperate in holding the object.

The invention relates to an interchangeable milling adapter (20) for a work table (60), which comprises a receptacle (21) for a milling machine (70) and an angular adjustment (22). At the same time, an angular position (WP1, WP2) of the receptacle (21) in relation to the work table can be adjusted using the angular adjustment (22). Furthermore, a work table, a milling unit and their use for adjusting a milling machine are described.

A core support system includes a support structure. The support structure includes a frame and a support member having a saturatable engagement layer disposed over the frame. A method of machining a core material incudes applying a fluid to an engagement layer of a support structure and saturating the engagement layer with the fluid, disposing a core material on the engagement layer, causing the fluid to freeze to secure to the core material to the support structure, machining the core material, melting the frozen fluid to release the core material from the support structure, and removing the core material from the engagement layer.

A substrate processing apparatus including a lower jig plate for arranging a substrate which is an object to be pressurized, columnar members supporting the lower jig plate, and a heat dissipating column contacting the lower jig plate directly or indirectly and having a higher heat dissipation property than the columnar members.

An electrical discharge machining (EDM) fixture for machining a part includes a support structure fixable onto a work surface, a base plate fixed to the support structure, a toggle clamp positioned on one side of the base plate, and a secondary clamp positioned on an opposite side of the base plate. A plurality of contact points are respectively associated with the toggle clamp and the secondary clamp, and a tool ball is fixed to the base plate.

The invention relates to a negative-pressure element for arrangement in and/or on a negative-pressure work surface in order to selectively illuminate said negative-pressure work surface, the negative-pressure element comprising: at least one connection which is designed to connect a negative pressure and/or a negative-pressure device; a diffuser layer, the diffuser layer having a perforation at least in sections; a translucent layer, in particular a light-guiding layer, the translucent layer having a perforation at least in sections and being designed to couple light into the diffuser layer; wherein the perforation of the diffuser layer and of the translucent layer is designed such that, when a negative pressure is applied to the negative-pressure element, air can flow through said perforation towards the negative-pressure device; at least one light source, in particular at least one LED, which is configured to emit light towards the translucent layer; at least one volume which is designed to distribute a negative pressure applied to the at least one connection to the perforation, in particular to at least one part of the perforation; and wherein the negative-pressure element is designed such that it can be arranged on a perforated negative-pressure work surface or such that the negative-pressure element can be integrated into a recess in a work surface or a negative-pressure work surface.

A modular tabletop apparatus, typically used for workpiece storage and handling during robotic manipulation and feeding to a machine, is disclosed. Modules of the apparatus comprise detection interfaces disposed at locations corresponding to module edge locations and arranged in a periodic grid. Alignment of facing detection interfaces along common edges of pairs of adjacent modules permits module controllers to detect neighboring modules, and a main controller to compute the overall size and shape of the tabletop formed by the modules. Connecting arrangements are also disclosed. The connecting arrangements may be placed at the same grid locations as the detection interfaces, advantageously permitting alignment of detection interfaces for any interconnection configuration of modules. Modules may comprise plates with a grid of positioning indentations. The period of the positioning grid can be an integer multiple or integer fraction of that of the interface/connection grid.
