A headstock structure of computer numerical control milling and boring machine tool comprising a spindle, a conducting slip ring, a rotating plate, a mobile unit, two balancing units, a driving unit, and a cutter locking unit; the conducting slip ring being sleeved on a top end of the spindle; the rotating plate being rotated in horizontal direction under the drive of the spindle; the mobile being rotated in horizontal direction together with the rotating plate; the two balancing units being located on the rotating plate; the driving unit being configured to drive the mobile unit to perform horizontal radial movement; the cutter locking unit being configured to lock the cutter, so that the headstock structure can rotate and move up and down, and can perform horizontal radial motion.

A portal-type positioning device includes two parallel linear guides provided with integrated linear drives, which support a separate X-carriage in a manner that allows movement in the X-direction, as well as a cross beam which is connected to the two X-carriages and movably supports a carriage in a Y-direction that extends perpendicular to the X-direction, with the aid of an integrated linear drive. In addition, the positioning device has a tool holder, which is guided on the Y-carriage in a Z-direction and holds a tool for machining a workpiece situated in an X-Y plane, the tool being disposed next to the cross beam at an offset in the X-direction. A force frame disposed above the tool in the Z-direction transmits a process force acting on the tool to the carriages LX1, LX2 without deforming the cross beam by a torque. The process force is applied by an electromagnet which acts between the force frame and the tool holder.

An air balance mechanism includes a plate part, fixed shafts, and movable cylinders. A flange is provided at one end of each of the fixed shafts. The movable cylinders are movable relative to the fixed shafts. A space is formed below a lower surface of the flange. Further, the air balance mechanism includes fixing bolts and adjusting bolts. The fixing bolts fix the flange and a plate part at positions different from the space. The adjusting bolts are inserted into the plate part through the space for allowing the postures of the fixed shafts to be adjustable.

The present invention relates to an anterior spindle device for use on a machine tool, comprising a clamping interface 12 for clamping the anterior spindle device on a work spindle of the machine tool, an anterior spindle unit 14 with a spindle 14a for driving a drilling tool clamped on the spindle 14a, a drive 15 for exerting a force on the anterior spindle unit 14, and an electromagnetic actuator 16 for exerting a counterbalancing force opposite to the force of the drive 15 on the anterior spindle unit 14.

A flexible mechanism and a gantry device having the same are provided. The flexible mechanism serves to compensate the positional space error caused by synchronous error, deformation or the like factor of the gantry beam. The flexible members serve to enhance the rigidity in the direction of the motional axis, in which the external force is applied to the beam. This can avoid hysteresis phenomenon of the beam during operation.

A transfer center for machining at least one workpiece is disclosed, having a machine frame, having a plurality of preferably stationary machining spindles arranged in the machine frameparticularly in a machining head, having a workpiece carrier on which at least one workpiece to be machined is arranged by means of a respective clamping device, and having a workpiece manipulator arranged in the machine frame, onto which workpiece manipulator the workpiece carrier is flange-mounted and which is movable by drive means in at least one spatial direction in relation to the machine frame. To achieve a high machining accuracy in parallel machining, according to one proposal, the transfer centerin order to compensate for a deviation between the actual position and the desired position of the workpiece or workpieceshas a position compensation system with at least two pressure elements situated between the workpiece or workpieces and the machine frame, whose operating directions enclose an angle with each other.
