A machine tool includes a stationary machine frame, a tool head, which is able to be positioned relative to the machine frame along three mutually orthogonal translation axes, and a motor-driven tool. The machine tool includes a swivel unit, which can be pivoted about a horizontal swivel axis relative to the machine frame and includes a workpiece positioning device, via which a workpiece can be rotated about an axis of rotation oriented perpendicularly to the swivel axis. The swivel unit is assigned a measuring frame, which is able to be rotated with the swivel unit and is arranged to be thermally and/or mechanically decoupled from the swivel unit and includes components of a first and second position measuring system. Additional components of the first position measuring system are disposed on the tool head, and further components of the second position measuring system are situated on the workpiece positioning device. The spatial position of the tool head in relation to the measuring frame is ascertained via the first position measuring system, and the spatial position of the workpiece positioning device in relation to the measuring frame takes place via the second position measuring system.

A milling machine including a frame (2) having a work surface (2.1) disposed in a vertical plane and a C-shaped moving bridge (3). In addition, the machine includes: at least three heads (7), each head including a machining spindle (15); and five movement axes (X, Y, Z, A, B), such that the moving bridge (3) is moved by the frame (2) along a horizontal axis (X). Each head (7) is moved independently on the moving bridge (3) along a vertical axis (Y) in order to be moved towards or away from the work surface (2.1) along a depth axis (Z) perpendicular to both the horizontal axis (X) and the vertical axis (Y), as well as rotating independently about a first axis of rotation (A). Each spindle (15) rotates independently about a second axis of rotation (B).

Methods and devices for milling a channel-shaped cavity by a five-axis computer numerical control (CNC) machine by selecting a workpiece to be machined, determining cutting tool flow along the channel-shaped cavity, determining cutting tool in-depth penetration, determining a trochoid path, and determining auxiliary movements.

A numerical control machine-tool includes: a ground-resting base plate; a movable supporting column rising cantilevered from the base plate in a substantially vertical direction and movable horizontally on said base plate; a first electronic-controlled drive assembly for moving the supporting column along the base plate; a head-carrier slide fixed in vertically sliding manner in a straight longitudinal slit extending along the front face of the supporting column parallel to the longitudinal/vertical axis of the supporting column; a second electronic-controlled drive assembly for moving the head-carrier slide along the supporting column; a straight supporting beam inserted in an axially sliding manner into the head-carrier slide and cantilevered juts out from the front face of the supporting column while remaining substantially parallel to the ground; and a third electronic-controlled drive assembly for moving the supporting beam forwards and backwards with respect to the head-carrier slide parallel to the beam longitudinal axis.

The invention provides a milling cutter equipment for an elevated floor, which is used for milling a plurality of ejector pin structures on the back of the elevated floor. The milling cutter equipment includes a conveying device and a plurality of milling cutter ejector pin devices. The milling cutter ejector pin device includes an elevating device and a milling cutter set device. The milling cutter set device has a plurality of milling cutter bodies. By the use of the above mentioned devices, the conveying device carries the elevated floor and moves it above the elevating device. The elevating device then pushes the elevated floor away from the conveying device and is contacted against the milling cutter set device, and uses the milling cutter body to move it relative to the milling cutter set device and perform milling to the corresponding ejector pin structure.

The application describes a machine tool adapted and arranged to carry out removal and addition of material on a work piece located in a work station, the machine having a first head arranged to remove material from the work piece and at least a second head arranged to process the work piece, each of the first and second heads being arranged to be moveable in at least two axes and preferably in 3, 4 or 5 axes and wherein the machine is arranged to control an environment of the work station. The work station is at least partially sealable. The machine has a clean side and a dirty side. Novel processing heads particularly adapted for use in the new machine tool are disclosed. These may also be retrofitted to CNC machines. The novel heads include heads adapted to carry out two processes simultaneously. Heads adapted to carry out heat and pressure treatment are also disclosed. Use of the processing heads to carry out analysis in manufacturing steps is disclosed as is the provision and use of heads that can carry out analysis as well as processing.

A machine tool system has a machine tool with a stationary machine base, support elements connected to the machine base, and a crossbeam connected to the support elements. The crossbeam is adjustable relative to the support elements in a Z-direction or the support elements are adjustable relative to the machine base in an X-direction. A tool holder head is mounted on the crossbeam and adjustable for travel in a Y-direction along the crossbeam. The X-, Y- and Z directions form a cartesian coordinate system. A control facility is connected to the machine tool for controlling travel in the Y-direction and adjustment in at least one of the X- and/or Z-directions based on a kinematic parameter specified as a function of a position of the tool holder head relative to the Y-axis and thus takes into account asymmetric load distribution caused by movement of the tool holder head.
