The invention relates to a machining device, in particular for machining workpieces made from wood, wood materials, plastic or the like, having at least one workpiece table with a first workpiece holder for holding at least one workpiece, furthermore with a second workpiece holder for holding at least one workpiece, wherein the workpiece can be positioned in at least two dimensions, advantageously in three dimensions, during a re-clamping operation from the first workpiece holder into the second workpiece holder.

A machine tool system includes: a machine tool that machines a workpiece by using a tool attached to a spindle; and a plurality of robots installed inside a machining space of the machine tool and adapted to grip the workpiece and move the workpiece in conformity with the machining performed by the machine tool.

A machine tool system includes: a machine tool for machining a workpiece set on a table using a tool attached to a spindle; and a robot for gripping the workpiece. The robot is installed on the table and performs a setting operation for setting the workpiece on the table and a clamping operation for clamping the workpiece.

Auxiliary spindle AS for clamping at least one workpiece W on a tool holder turret 200A-200D for machining operation, in particular a tool holder turret 200A-200D of a lathe having at least a spindle unit 310 configured to mount the auxiliary spindle AS onto turret port of a tool holder turret 200A-200D and receive a workpiece W for machining operation of the received workpiece W on the tool holder turret. In addition, the spindle unit 310 further includes at least a receiving unit 311 configured to clamp the workpiece W onto the auxiliary spindle AS.

A machining center equipped with a device for mounting on a clamp parts to be worked or which have been worked, such as profiles, which has a supporting frame for supporting a turntable with two or more stepped positions or placements or workstations, an loading basket and an unloading basket. The machining center comprises a robot configured to remove or to associate, with each one of said two or more stepped positions or placements or workstations, the parts or the profiles to be worked and which have been worked at a plurality of fixed RPS or reference points and mobile mechanical components, according to a single positioning that is adapted to allow access by machining devices to any zone in the space of the profiles to be worked by modifying only the condition that the two or more stepped positions or placements or workstations are in.

A conveying apparatus conveys an article between a wait position and a processing position. The conveying apparatus includes a plurality of arms that sandwiches the article between leading ends of the arms located on opposite sides of the article and that is provided to enable base ends of the arms to turn so as to move the leading ends in an up-down direction, and a control apparatus that turns the arms to lift the article located at one of the wait position and the processing position and sandwiched between the arms and that moves the arms with the article kept lifted thereby to the other of the wait position and the processing position, the control apparatus turning the arms to lower and mount the article at the other of the wait position and the processing position.

A dental milling machine has idle receptacles arranged in a storage chamber for storing a plurality of blanks. The blanks each are placed without frame as a frameless blank in the idle receptacles. A transfer device with a transport arm is arranged in the storage chamber. A work chamber adjoins the storage chamber. A transfer opening is arranged between work chamber and storage chamber. The transport arm grips a frameless blank stored in the storage chamber and moves it through the transfer opening into the work chamber. A workpiece holder arranged in the work chamber receives the frameless blank from the transport arm. The workpiece holder grips the frameless blank by a receiving rim of the frameless blank. The workpiece holder, for milling the frameless blank in the work chamber by a milling tool, holds by a clamping action the frameless blank at the receiving rim.

A machining system includes: a working machine that machines an article while supplying a dielectric working fluid to the article; a robot that transports the machined article from the working machine; a controller that controls the robot; and a recessed wall part that is provided outside the working machine so as to demarcate the transport path of the article. The robot includes a gripping part that grips the article and a rotating part that rotates the gripping part. The controller is configured to move the gripping part with the machined article along the transport path while rotating the gripping part in the recessed wall part by means of the rotating part.

A rotary indexing machine comprises at least one indexing plate, which is in at least one operating state configured to accommodate and transport at least one work piece, and with at least one clocking cell comprising at least one accommodating unit with at least two opposite-situated accommodating elements, which are configured for together accommodating the at least one work piece from the indexing plate, and comprising at least one machining unit for machining the work piece accommodated by the accommodating unit, wherein the at least one clocking cell comprises at least one bridge unit, which extends at least partially over the indexing plate in an axial direction and is configured to guide the at least two accommodating elements of the accommodating unit in a shared coordinate system.

A chuck mechanism enables downsizing of the device with a simple structure, has a wide open/close width of clamps, and hardly causes a dent or scar on pipes. The chuck mechanism includes a horizontally arranged shaft, a frame, a pair of dog leg shaped link members, parallel link members, a pair of clamp members, and a swing drive mechanism.
