A machining apparatus includes: a shuttle unit (3) that holds a differential case (10) and rotates the differential case (10); a pair of opposed right and left machining units (4); and a tool support (6) that supports a tool (40) for machining the differential case (10), in which the pair of right and left machining units (4) each include a slide mechanism dedicated for uniaxial sliding in right and left directions, the shuttle unit (3) is movable in up and down directions and front and back directions, a tool attached to each of the pair of right and left machining units (4) enables machining an end portion of an inner surface of the differential case (10) and a flange hole of the differential case (10), the end portion surrounding a through hole, and a cutting edge of the tool (40) supported by the tool support (6) enables spherically cutting the inner surface of the differential case (10) held and rotated by the shuttle unit (3).

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.

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.

A machine tool comprises a machine frame, a first spindle having a first workholder rotatable about a first axis, a second spindle having a second workholder rotatable about a second axis, a first tool carrier for machining one side of a workpiece in the first spindle, and a second tool carrier for machining a different side of a workpiece in the second spindle. The second spindle is arranged on a spindle carrier movable relative to the machine frame, using a carriage system, in parallel with and transversely to the first axis. The second workpiece spindle is pivotal on the spindle carrier, using a pivoting device, about a pivot axis that extends perpendicularly to a movement plane. The second tool carrier is positioned on a guide carriage movable relative to the machine frame in parallel with the pivot axis. A drag frame conveyor is provided to feed or transport workpieces.

A workpiece information recognition system includes a workpiece placing tool (20) capable of placing a workpiece, a reference block (31) detachably provided on workpiece placing tool (20), an information detector configured to detect information about reference block (31), and a control device configured to receive the information of reference block (31) from the information detector. The control device includes a storage configured to store data on a relationship between the information about reference block (31) and information about the workpiece and a controller configured to recognize the information about the workpiece placed on workpiece placing tool (20) by checking the information about reference block (31) detected by the information detector with the data stored in the storage. With this configuration, the workpiece information recognition system capable of easily cope with a change in a type of the workpiece is provided.

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 method and a system for handling slender bodies in a semi-finished production plant includes a cutting station separating slender bodies from a continuous wire, a finishing station of the head ends of the slender bodies, a dimensional verification station downstream of the finishing station, and transporting equipment transporting the slender bodies between stations. At or upstream of the cutting station a marking unit applies a reference marking on the slender bodies, which working identifies an original attitude including angular position. The transporting equipment includes gripping and locking assembly, locking at least the angular position of the reference mark to a relative reference system of the transport equipment. Upstream of the finishing station is a detecting and storing unit for data of the angular position to the relative reference system. A unit determines the original attitude of the slender bodies using the data in the dimensional verification station.

The collecting mechanism includes a holding unit and a controller. The holding unit has a pair of arms, and can sandwich a machined portion with the pair of arms. The holding unit can be switched between a holding state and a standby state. In the holding state, the pair of arms is closed to be in contact with the circumferential surface of the machined portion to sandwich the machined portion. In the standby state, the pair of arms is opened so as to stay near the circumferential surface of the machined portion with a space between the arms and the circumferential surface of the machined portion. The controller monitors whether cutting-off of the machined portion has been completed to keep the holding unit in the standby state before completion of the cutting-off and to switch the holding unit from the standby state to the holding state at the time of completion of the cutting-off.
