For a turning machine (1) that can be used for rotary turning, the tool holder (20) is hydrostatically mounted. A method corresponding to this is described, and it is provided to use a hydrostatic bearing (8, 9) for the damping of mechanical vibrations of a tool holder (20) and/or for the permanent mounting of a tool holder (20) of a turning machine (1).

A vertical lathe, including: a headstock provided on the upper side of a base so as to be capable of moving in the lateral direction and the vertical direction; a main spindle rotatably supported by the headstock; a workpiece chuck provided at the lower end section of the main spindle; a turret support stand provided so as to be capable of moving in the longitudinal direction orthogonal to the lateral direction and the vertical direction; an actuator for moving the turret support stand in the longitudinal direction; a turret having tool mounting parts provided at a plurality of circumferential positions, the turret being supported by the turret support stand so as to enable turn-indexing about the axis in the longitudinal direction; and a plurality of processing tools attached at each of the tool mounting parts so as to be set apart from each other in the longitudinal direction.

A numerical controller performs control to rotate a turret, which holds a plurality of tools on the outer peripheral portion thereof, thereby moving one (selected tool) of the tools selected by a command to a predetermined position (selected position). The numerical controller sets and holds a partial area of the outer peripheral portion of the turret as an area (passage-prohibited area) prohibited from passing through the selected position and determines whether or not the selected tool is present in the passage-prohibited area or whether or not the passage-prohibited area passes through the selected position as the selected tool is moved to the selected position.

Provided is a machine tool (1) capable of effectively removing machining chips adhering to a portion excluding a held portion and including a machining working portion of a tool (T). The machine tool (1) includes a tool holding unit (6) holding the tool (T), a feed mechanism (10, 11, 12) moving the tool holding unit (6) in at least one axis direction, an enclosure (22) provided within an operating area of the tool (T), having an opening, and having an interior area into which a portion of the tool (T) exposed outside from the tool holding unit (6) can be partially or entirely enclosed through the opening, a fluid injecting nozzle (23, 24) provided on at least one of the tool holding unit (6) and the enclosure (22) and injecting a fluid toward the tool (T) enclosed in the enclosure (22), and a controller (15) controlling the feed mechanism (10, 11, 12) such that the tool (T) is enclosed into the enclosure (22) by moving the tool holding unit (6), and controlling an injecting operation of the fluid injecting nozzle (23, 24) such that the fluid is injected in a state where the tool (T) is enclosed in the enclosure (22).

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.

The present invention discloses an efficient brake disc processing device, which relates to the technical field of brake disc processing, comprising a lathe bed, an upright vertical lathe and a first power tool holder installed on a top end of the lathe bed, and an inverted vertical lathe and a second power tool holder installed on a rear side of the top end of the lathe bed, wherein the upright vertical lathe is cooperated with the second power tool holder to process an upper brake surface of a brake disc, and the inverted vertical lathe is cooperated with the first power tool holder to process a lower brake surface of the brake disc.

A multifunctional end effector includes a support structure configured to be carried by a robotic system and at least two of a fluid stream cutting system, a spindle system and/or a scanning system, each mounted to the support structure. Also described is a fluid stream cutting system having a plurality of fluid stream catchers selectively mountable to the fluid stream system and a mounting arrangement for mounting each fluid stream catcher to the fluid stream cutting system.

A CNC turning and milling machine includes: a base, a moving unit, a spindle unit and a turret unit. The spindle limiting unit and the turret limiting unit are employed to limit the movement range, and the spindle unit and the turret unit are fixed on the upright post to strengthen the overall structural strength and reduce vibration during processing, thereby improving machining accuracy and processing efficiency, while reducing surface roughness.

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.
