The present invention is provided with: a first processing position (A1) and a second processing position (A2) at which rough processing is performed on a workpiece (W); a third processing position (B1) at which final finishing processing is performed on the workpiece (W) that was processed at the second processing position (A2); flexible vices (7) provided to the first processing position (A1) and the second processing position (A2), the flexible vices (7) securing the workpiece (W) by clamping the same; and a quick clamping device (20) provided to the third processing position (B1), the quick clamping device (20) securing the workpiece (W) by means of a pin. The present invention is also provided with a control unit that controls a rough processing tool for performing rough processing and a final finishing processing tool for performing final finishing processing.

A wafer producing apparatus includes an ingot grinding unit that grinds the upper surface of an ingot to planarize the upper surface, a laser irradiation unit that positions the focal point of a laser beam with such a wavelength as to be transmitted through the ingot to a depth corresponding to the thickness of a wafer to be produced from the upper surface of the ingot and irradiates the ingot with the laser beam to form a separation layer, a wafer separating unit that separates the wafer from the ingot, and a tray having a support part that supports the separated wafer.

A station for treating objects may include: a booth including at least one entrance for an object and at least one exit for the object; a system configured to move the object between the at least one entrance and the at least one exit; at least one robot configured to treat the object in the booth; and/or a platform configured to support the object. The platform may be configured to rotate about a vertical axis so as to rotate the object inside the booth relative to the at least one robot. The at least one entrance may not be aligned with the at least one exit. The system may be configured to rotate with the platform so as to align with the at least one entrance in order to receive the object, and so as to align with the at least one exit in order to release the object.

A pallet changing apparatus which adopts a table 4 that is able to move back and forth in relation to a turning shaft 1 and has a oscillating portion 41 for placing workpieces W, W by way of pallets P, P so as to oscillate freely by a rising portion 42 at the leading end of the table, and a bridging extending portion 31 which bridges a supporting portion of pallet P or P in a pallet changing arm 3 with both sides of the turning shaft 1 forming a shape of covering across the upper side of the rising portion 42 at a stage of the table 4 transferring pallet P.

An automatic manufacturing station (3) and a manufacturing process for workpieces (2), in particular for vehicle body parts, has a manufacturing area (4) with a plurality of program-controlled manufacturing robots (9). The workpieces (2) are externally fed to the manufacturing station (3) on production load carriers (8). The manufacturing station (3) also has a plurality of work stations (10, 11, 12, 13). A station-bound transport device (15) transports the production load carriers (8) within the manufacturing station (3).

A pallet changing apparatus adopting a table 4 capable of moving back from and forth for a side of a turning shaft 1 and having a oscillating portion 41 for placing workpieces W, W by means of pallets P, P so as to oscillate freely by an upright portion 42 at the leading end of the table 4, wherein the turning shaft 1 covers a turning supporting portion 11 at its lower end side and turns together with a pallet changing arm 3 and moves freely in a vertical direction, and an insertion and removal hollow space 20 is provided, at the covering region, and allows the upright portion 42 to be inserted into the insertion and removal hollow space 20 and removed from the insertion and removal hollow space 20.

The system includes a cell framework for defining a manufacturing area. The system includes at least one workplace within the manufacturing area. The system includes at least one manufacturing component within the manufacturing area and configured to be movable along three axes in relation to the at least one workplace. The system includes a conveying mechanism configured to move a part into the at least one workplace to be worked on by the at least one manufacturing component.

A machining center includes a machine bed, a work table unit, a sliding unit, a first driving unit, a conveying member, a second driving unit and a loading seat. The machine bed has a machining zone and a transferring zone. The first driving unit is operable for driving the conveying member to move along a conveying axis which extends in a first direction, thereby driving the loading seat to move along first adjusting axes which extend in the first direction between the transferring and machining zones. The second driving unit is operable for driving the loading seat to move along second adjusting axes which extend in a second direction, which is perpendicular to the first direction and which is substantially vertical.
