Certain exemplary embodiments can provide a system comprising a machine tool, a centerable holder, and a drill. The machine tool comprises a spindle and a tool holder. The centerable holder is pointed at the spindle of the machine tool. The centerable holder defining a pair of horizontal adjusters and a pair of vertical adjusters.

In one aspect, a swiss-type machine tool is provided that includes a workpiece holding shaft, a workpiece supporting shaft, and a tool holder associated with the workpiece supporting shaft for holding at least one tool. The machine tool includes a drive operable to rotate the workpiece holding shaft and the workpiece supporting shaft around an axis. The workpiece holding shaft has a work holder configured to secure a workpiece to the workpiece holding shaft. The workpiece holding shaft is axially shiftable relative to the workpiece supporting shaft to adjust a position of the workpiece relative to the workpiece supporting shaft. The machine tool further includes a removable workpiece support, such as a guide bushing, configured to be releasably connected to the workpiece supporting shaft and rotate therewith. The workpiece support slidably contacts the workpiece and permits axial movement of the workpiece relative to the workpiece support.

A complex machine tool for cylindrical workpieces has a bed, a headstock assembly, at least one supporting assembly, and at least one machining assembly. The bed has three tracks being respectively a first track, a second track, a third track arranged in order. Each one of the three tracks defines a respective guiding direction, and the three guiding directions of the three tracks are mutually parallel. The headstock assembly is connected to the bed, and is located near one of two ends of the second track. The at least one supporting assembly is mounted on one of the three tracks and is used for supporting the cylindrical workpiece. The at least one machining assembly is mounted on one of the three tracks, is slidable along the track, and is located on a position at a spaced interval from the at least one supporting assembly.

A tooling assembly for a lathe machine includes a tool platform configured to be mounted on the lathe machine, a milling tool holder fixedly secured to the tool platform and workable to releasably secure a thread milling tool therein, and a milling tool drive. The milling tool drive is operatively connected to the milling tool holder and operable to rotate the milling tool holder independently of a work holder to mill threads on the workpiece when a pipe thread milling tool is secured in the milling tool holder. Computer numerical control threading lathes and methods of milling threads in tubular workpieces are also described.

Provided is a machining method for a workpiece that is rotated in a machine tool having a main spindle, in which modification of the machine tool is not necessary when machining the workpiece. The machining method for the workpiece includes: a first mounting step in which a workpiece holder that is holding the workpiece is mounted onto the main spindle of the machine tool; and a first machining step in which the main spindle is rotated and the workpiece is machined by a first tool installed on a table of the machine tool.

A machine tool is provided which can execute various works while suppressing increase in cost or size. The machine tool includes a tool spindle device which is a movable member which can move with respect to a mounting surface of the machine tool, and one or more serial-manipulator-type robots attached on the tool spindle device, which can move with the tool spindle device, and which have two or more degrees of freedom, and the robot includes two or more end effectors provided at positions different from each other with one or more joints therebetween.

In a working machine, left and right side walls are erected on a bed, a forward/backward saddle is movable in forward/backward directions, left and right sides of the forward/backward saddle are movably supported with the left and right side walls, a forward/backward drive device is arranged on the left and right side walls, to move the forward/backward saddle in the forward/backward directions, a left/right saddle is arranged on the forward/backward saddle and movable in left/right directions, a left/right drive device is arranged on the forward/backward saddle on each of forward/backward sides of the left/right saddle, to move the left/right saddle in the left/right directions, an up/down slider is movable up and down and arranged on the left/right saddle, a lower portion of the up/down slider is provided with a processing head to which a processing tool for processing a work set on the bed is removably and replaceably attached.

Certain exemplary embodiments can provide a system comprising a machine tool, a centerable holder, and a drill. The machine tool comprises a spindle and a tool holder. The centerable holder is pointed at the spindle of the machine tool. The centerable holder defining a pair of horizontal adjusters and a pair of vertical adjusters.

A machining head is provided with a turret on which multiple rotating tools are mounted, and this head is configured such that rotation of each of the multiple rotating tools during machining and rotation of the turret are performed by a single motor. A switchable turret rotation transmission mechanism is disposed to be capable of transmitting the rotation of the motor shaft to the turret as the rotation of the turret and releasing the transmission. The rotation of each of the multiple rotating tools during the machining and the rotation of the turret can be performed by the single motor.

A machine tool has at least 5. A tool holder assembly permits a tool holder spindle to be displaced relative to the frame along a first axis of translation and along a second axis of translation perpendicular to the first axis of translation and implementing slides in a plane forming an angle of between +40° and +50° relative to the first axis of translation. A part holder assembly permits a part to be displaced along a third axis of translation perpendicular to the other axes of translation, about a first axis of rotation parallel to the third axis of translation and about a second axis of rotation perpendicular to the first axis of rotation. The length of the precision path connecting the part to the tool via the frame and the assemblies of the machine is less than 1600 mm.
