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.

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.

A manufacturing machine is capable of subtractive manufacturing and additive manufacturing for a workpiece. The manufacturing machine includes: a first headstock and a second headstock disposed in a machining area and configured to hold a workpiece; a tool spindle and a lower tool rest disposed in the machining area and configured to hold a tool to be used for subtractive manufacturing for the workpiece; an additive manufacturing head configured to discharge a material during additive manufacturing for the workpiece; a workpiece gripper configured to grip the workpiece during transportation of the workpiece into and out of the machining area; and a robot arm on which the additive manufacturing head and the workpiece gripper are mountable. Accordingly, the manufacturing machine improving the productivity in the simple and easy manner is provided.

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.

A lathe includes a lathe-side chuck that holds a workpiece with the workpiece directed toward or facing a front side, a main spindle that rotates around an axis, and a tool that machines the workpiece. A machining center includes a rotary tool that rotates around an axis in the horizontal direction and an MC-side chuck that holds the workpiece and is able to turn between at least a workpiece pass/receive position in which the workpiece is directed toward or facing the front side and a machining position in which the workpiece is directed toward or facing the rotary tool. A loader includes a guide rail extending above the lathe-side chucks, and MC-side chuck along the horizontal direction and a loader head that holds the workpiece and carries the workpiece between at least the lathe-side chucks, and MC-side chuck by moving along the guide rail.

A sealing fin fixing apparatus can fix a sealing fin to a rotor in a shortened period of time to minimize variations of the pullout strength of the sealing fin. In the sealing fin fixing apparatus that fixes the sealing fin in a sealing groove defined in the outer circumference of the rotor of a rotary machine and includes a headstock for setting a rotor thereon, a Z-stage movable along a Z-axis, an X-stage movable along an X-axis, a tool rest supported on the X-stage, and a caulking tool mounted on the tool rest and including a shank and a pressing roller, while the pressing roller is being held against a caulking wire inserted, together with the sealing fin, in the sealing groove in the rotor that is set on the headstock, the headstock is actuated to rotate the rotor, thereby caulking the caulking wire to fix the sealing fin to the rotor.

The tool holder device for broaching and slotting, comprising: one main frame associated with one machine adapted to machine one workpiece; one working assembly associated with the main frame and comprising one supporting bar movable longitudinally along a first axis and a guiding mechanism for the supporting bar movable longitudinally along the first axis; one tool associated with the supporting bar and adapted to machine the workpiece; angular adjustment mechanism for adjusting the supporting bar, interposed between the main frame and the guiding mechanism and adapted to rotate the supporting bar around a second axis substantially orthogonal with respect to the first axis; and straight adjustment mechanism for adjusting the tool with respect to the supporting bar, interposed between the tool and the supporting bar, the straight adjustment mechanism being adapted to adjust the position of the tool along the second axis.

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.
