A workpiece fixture assembly is provided herein. The workpiece fixture assembly includes a baseplate including an engagement surface. First and second static risers are configured to maintain a position of a workpiece. The first static riser includes a first gage bore thereon. A dynamic riser is configured to abut the workpiece and has a second gage bore thereon. A numerical control machine has a probe to measure an offset distance between the first and second gage bores. A linearly actuable workpiece support is disposed on the baseplate.

Provided is a clamp system with enhanced functionality achieved by detecting the behavior of an object to be clamped, using a stroke-end position detector that has been used for switching stroke operations. A clamp device 1 has an output member 12 which executes a stroke movement causing a change in the distance by which a coil 15 is inserted into a hole 14 having a bottom. A converter 23 outputs a measurement value of the inductance of the coil 15. The inductance of the coil 15 when a work W has been clamped by the output member 12 is stored in a work clamp point memory 22e, and a clamp area indicating a variation range permitted with respect to a work clamp point is set in a clamp area memory. During processing of the work, a control unit 2 measures the inductance of the coil 15, determines whether the work clamp point is within the range of the clamp area, and, if the range is exceeded, issues a signal indicating an emergency stop.

A grip device for locking metallic bodies destined for machining by means of machine tools, comprising at least one accommodation body for the bottom of a cylindrical container, the accommodation body being supported by a table that can move with respect to a supporting frame, the accommodation body accommodating an annular membrane that has at least one portion which can be deformed in a radial direction, the annular membrane being associated, on opposite sides with respect to the deformable portion, with a respective presser body, an actuator being provided which is adapted to move the presser bodies on command mutually closer and apart; the actuation elements comprise mechanical elements for kinematic transmission which can be operated following the relative movement of the movable table with respect to the supporting frame.

The application is related to adjustable supports for holding objects in one or more desired fixed orientations, including but not necessarily limited to objects that lack uniformity as to size and/or shape and/or weight.

The invention relates to a holding system having a holding device (1) and an abutment blank (6), to a method for retaining and machining an abutment blank (6), and to a holding device (1) for retaining an abutment blank (6) having an implant interface (8) and a retainer segment (7) spaced apart from the implant interface (8), comprising a recess (3) in a basic body (2) for forming a frame having interior contact surfaces. One of the contact surfaces is spaced apart from the opposite contact surface such that a processing space (30) is formed, into which the abutment blank (6) to be machined extends. One of the contact surfaces has at least one retaining receptacle (5), which preferably is a tapped blind hole, and which corresponds to the retainer segment (7), preferably in a friction-locking manner, such that the retainer segment (7) of the abutment blank (6) is retained in the retaining receptacle (5) in a rotationally secure manner and is oriented in a predetermined position.

A switch housing body has a base and a sidewall having an axis and extending from the base to a rim and having a pair of axial slots. A switch cap has: a cap body having a top web; and a sidewall extending from the top web to a rim and having a pair of holes. A shaft passes through the pair of axial slots and pair of holes. A spring biases the cap axially away from the housing from a compressed condition to an extended condition. A cap electrical contact and a housing electrical contact have an electrically closed condition at the compressed condition.

A system is disclosed for processing a plurality of customized dental restorations from individual millable material blocks in an automated process. The system comprises processing units that may comprise one or more of a milling center comprising one or more milling units, a plurality of material blocks a separating unit, a scrap disposal unit, a heating unit and a cooling unit. A carrier for holding a plurality of individual workpieces in spaced arrangement is also disclosed for use in the system.

A strut (6) of a circular plug projects upward from a main body (4) of a housing (3) and inserts into circular hole (9) of work (8). An opening (20) is formed laterally in a left portion of peripheral wall (18) of strut (6), a cam portion (28) projects leftward from a right portion of the peripheral wall (18). A positioning rod (22) inserts into insertion hole (14) in upper portion of housing (3) which is movable vertically and radially. A cam surface (32) is provided vertically on upper right portion of positioning rod (22), and pushing portion (33) is provided on upper left portion thereof. When a driving arrangement (D) drives positioning rod (22) downward for locking, cam portion (28) pushes the cam surface (32) leftward, and pushing portion (33) passes through opening (20) to press inner periphery of the circular hole (9) of work (8).
