The present invention discloses a double-swing angle spindle head, in which an A-axis swing shaft is connected to the spindle head through the flange on the end face to realize the swing of the A-axis, and a crank connecting rod mechanism composed of a first rotating shaft, a second rotating shaft, a B-axis rotating shaft and a swing connecting rod realizes the swing of the B-axis under the push-pull action of the B-axis mechanism. Under the action of the linear push-pull mechanism, the linear axis feed movement between a ram and a saddle is realized. Thus, the freedom of movement range of the spindle head is improved, the rigidity, torque and precision of the spindle head are enhanced, and the volume and weight of the spindle head equipment are reduced.

A rotation device capable of improving safety includes a plurality of screw holes that each extend along the radial direction of a rotation member and each has an opening on a surface of the rotation member; and a stopper for preventing a screw disposed inside the screw hole from protruding to the outside of the opening, without interfering with insertion of a tool, for turning the screw, into the screw hole.

The present invention provides a linkage swing head structure, including: a base, a drive mechanism and a spindle. The drive mechanism includes: a power mechanism, a connecting rod mechanism and a lead screw. An end of the spindle is fixed with a cutter, and the spindle is fixed on an end of the connecting rod mechanism. An end of the connecting rod mechanism fixed with the spindle is sleeved on a support bearing, the connecting rod mechanism can rotate around the support bearing, the support bearing is fixed on the base, and the other end of the connecting rod mechanism is movably connected to the lead screw. An output end of the power mechanism is connected to an end of the lead screw. The connecting rod mechanism adjusts the rotation angle of the spindle by sliding on the lead screw. The drive mechanism of the present invention is far away from the spindle, and the interference range thereof to the spindle is small. The spindle can be automatically and continuously indexed, and can also perform linkage machining with small cutting amount, and thus, when the cutter rotates by the same angle, the volume of the device is reduced; the structure is simple and the manufacturing cost is low.

A machine tool comprises a frame, which carries a fixed gantry for supporting at least one tool spindle. The gantry comprises a gantry recess, through which a working space is accessible. The one or more tool spindles on the gantry can each be moved vertically in a first direction and in a second direction orthogonal to the first direction. The machine tool further comprises a workpiece table with at least one location for supporting workpieces. The workpiece table is movable in translation in a third direction Y orthogonal to the first direction and the second direction. At least one tool magazine is associated with the at least one tool spindle tool spindle. Tools for tool changing can be fed through at least one magazine opening in the gantry. Tool changing between the one or more tool spindles and the at least one tool magazine takes place in a pick-up process.

A machine tool capable of reducing entry of a workpiece chip into a product discharge chute. A controller controls a receipt of a product made of a workpiece held by a first spindle by a product receiver in a product receiving position, movement of the product receiver to a product dropping position and rotation of the product receiver to drop the product to the product discharge chute through an opening of the product discharge chute, and movement of the product receiver to the product receiving position to receive the product again. A second spindle is kept on standby in the product dropping position during which the opening of the product discharge chute is closed by the product receiver.

A motor spindle including a sleeve-shaped stator, which has a first coupling receptacle and a second coupling receptacle, further including a rotor, which has a first coupling part with axial fixed bearing and a second coupling part with axial loose bearing, which are to be mounted to the respective coupling receptacle, the axial loose bearing comprising an inner ring mounted to the rotor shaft and an outer ring arranged coaxially with the inner ring and mounted to the second coupling part, wherein the second coupling part is received on the rotor shaft so as to be axially movable parallel to the rotor axis between a first functional position and a second functional position along an adjustment path and wherein for the entire adjustment path there is a first distance between a first axial surface of the inner ring and the second coupling part and there is a second distance between a second axial surface of the inner ring and the second coupling part.

A miller, a non-transitory computer readable medium, and a method for milling a multi-layered object. The method may include (i) receiving or determining milling parameters related to a milling process, the milling parameters may include at least two out of (a) a defocus strength, (b) a duration of the milling process, (c) a bias voltage supplied to an objective lens during the milling process, (d) an ion beam energy, and (e) an ion beam current density, and (ii) forming a crater by applying the milling process while maintaining the milling parameters, wherein the applying of the milling process includes directing a defocused ion beam on the multi-layered object.

A tool holder assembly and insert body and activation system used with the assembly. The insert body of the tool holder assembly can be configured to shift as needed to engage tooling when the assembly is activated. In some cases, the insert body can be configured to shift further to better engage the tooling. The activation system can be electrical.

A linear motion mechanism includes: a shaft; a base member having a through hole through which the shaft can be inserted; a static pressure bearing provided between the shaft disposed in the through hole and the base member to slidably support the shaft relative to the base member by introducing a pressurized fluid to the shaft; and an annular member provided between the static pressure bearing and the base member to elastically support the static pressure bearing.
