The turret disk is configured to be rotatable, by a first driving means D1, around a disk axis X which is an axis of rotation of the turret disk H2. The turret unit T includes a second driving means D2 for pivoting the turret head H around a turret axis Y, and the second driving means D2 is an inverted motor.

A table assembly for a machine tool is provided. The table assembly has a slide, a rotatable table and a table rotation mechanism placed on board the slide and adapted to be driven to rotate the table about a vertical axis. The table rotation mechanism has at least one rotation assembly engaged with a ring gear of the table. The at least one rotation assembly has a torque motor having a vertical motor axis and a reduction gear having an inlet engaged with the torque motor, and an outlet pinion engaged with the ring gear of the table, coaxial to the motor axis. The machine tool is a milling machine or a gantry boring machine.

An outer rotor motor direct-drive drilling or milling machine, including a machine base, a frame, a mechanical driving component and an electrical control box, component. The frame is installed on the machine base, a mechanical transmission box component is installed on the frame, the electrical control box component is located on the top of the frame. A mechanical driving component includes an mechanical execution component and a lifting mechanism, the mechanical execution component is composed of a hollow shaft outer rotor motor and an output shaft assembly. The output shaft of the output shaft assembly and the hollow shaft of the outer rotor motor are fitted in the form of a key or a spline. This form of cooperation chooses the fit forms that can transmit the speed and torque of the motor and can move the output shaft axially.

The machine tool has a machine bed having a first horizontal linear guide and a second horizontal linear guide arranged at right angles to the first linear guide. On the first linear guide is arranged, in an axially displaceable manner, a workpiece clamping fixture, which is swivelable about a swivel axis oriented parallel to the second linear guide and is rotatable about a rotation axis oriented at right angles to the swivel axis. On the second linear guide a toque motor driven swivel arm is axially displaceable, the swivel axis of which is arranged parallel to the first linear guide and which on its free end bears a tool spindle, the axis of which is oriented parallel to the first linear guide.

The invention relates to a transport device comprising a transport element for receiving a workpiece, said transport element being movable by means of a motor from a first idle position into a second idle position, the transport element being drivably connected to at least one driver that engages in a drive groove of a drum cam that can be driven by the motor, which can be controlled by means of a programmable control device on the basis of a motor control curve. The drive groove has a variable incline at least in sections and the motor control curve also has a variable course at least in sections, the movement of the transport element being generated by a simultaneous superposition of a first movement component based on a region of variable incline of the drive nut and a second movement component based on a variable region of the motor control curve.

The present disclosure relates to a machine tool, in particular multi-spindle turning machine, comprising a machine frame, a turret body being rotatably supported by the machine frame, a plurality of workpiece spindles being arranged on the turret body, each of the workpiece spindles having a workpiece receiving portion for receiving a respective workpiece on one side of the turret body facing a working space of the machine tool, and a torque motor for driving a rotation of the turret body. The torque motor is arranged at a back end portion of the turret body opposite to the side of the turret body facing the working space of the machine tool, and a position locking mechanism for locking a rotational position of the turret body is arranged at a front end portion of the turret body on the side of the turret body facing the working space of the machine tool.

A three-axis tool head unit for a machine tool spindle, which comprises three components, which are rotatable or pivotable relative to each other about independent axes. A first head part is rotatably mounted on a support arm about a first axis with respect to the support arm. A second head part is rotatably mounted on the first head part about a second axis with respect to the first head part. A spindle device is rotatably mounted on the second head part about a third axis with respect to the second head part. The third rotary axis is oriented orthogonally to the first and the second rotary axes, while the first and the second rotary axes are inclined relative to each other. Each of the three rotary axes has an associated individual drive device for driving and controlling the rotation of the component about its respective axis.
