An attachment for converting a CNC milling machine to a CNC wire saw machine. The attachment may include a gantry that may be coupled with a respective gantry of the CNC milling machine, a carriage that may be attached to and moveable with a respective carriage of the CNC milling machine. A drive pulley of the system may be coupled with and driven by a spindle of the CNC milling machine. The drive pully may drive a wire saw through an assembly of idler pulleys. A wire tension mechanism may keep the wire fully stretched. The wire tension mechanism may include a curved guide rail mounted on the gantry and a vertical guide rail mounted on the carriage. A slider that slides vertically on the vertical guide rail and follows the curved guide rail may house a tension wheel that may keep the wire at a fully stretched state.

A machining center configured for machining workpieces includes at least one column, a beam, at least one slider, a first driving member, a second driving member, a first main shaft and a second main shaft. The column can be configured for supporting the beam. The slider can be disposed on the beam and slidable along a length direction of the beam. Both the first main shaft and the second main shaft can be arranged on the slider and located on two opposite sides of the beam. The first driving member can be configured for driving the slider to slide relative to the beam. The second driving member can be configured for driving the first main shaft and the second main shaft to operate. The first main shaft and the second main shaft can be configured for synchronously or asynchronously machining the workpieces.

A reconfigurable machining center includes a base structure extending in a first direction, a movable crossmember movable in the first direction and provided with a machining head, supporting elements on the base structure to enable movement of the movable crossmember along the first direction, a first leadscrew rack, integral with the base structure and having a first helical circular toothed sector, and extending along the entire base structure parallel to the first direction, and a first screw rotatably coupled to the movable crossmember and engaging a corresponding first leadscrew rack, and having a rotation axis parallel to the first direction. The longitudinal extension of the base structure in the first direction is an integer multiple of the pitch of tooth of the leadscrew racks, and the base structure includes coupling elements adapted to couple the base structure to a following and/or preceding adjacent base structure along the first direction.

The present invention discloses an overhead machining device based on a portable 5-DOF full parallel module. The overhead machining device based on a portable 5-DOF full parallel module comprises: a sliding table for moving a parallel module to increase the stroke of the machine tool such that the machine tool can machine large components and can also simultaneously conduct the mounting and the machining of workpieces at different stations; a CNC rotary table; and a portable 5-DOF full parallel module. The portable parallel module has a large swing angle range, can conduct the conversion between vertical and horizontal machining modes and can achieve five-face machining in one setup in cooperation with the CNC rotary table. The parallel module can move flexibly, and can machine large and complex components after mounted on the sliding table.

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 levelling machine includes a pair of spaced apart rail assemblies, a gantry assembly and a face mill assembly. The spaced apart rail assemblies define an x axis. The gantry assembly is moveably attached to the pair of spaced apart rail assemblies whereby the gantry assembly defines a y axis. The gantry assembly is moveable in the x axis along the pair of spaced apart rail assemblies. The face mill assembly is moveably attached to the gantry assembly and is moveable in the y axis along the gantry assembly. The face mill assembly has a plurality of saw blades, the saw blades being generally in an x-y plane defined by the x axis and y axis. The saw blades have a plurality of teeth that extend downwardly generally in a z axis. The face mill assembly is moveable in the z axis.

An all-directional profiling machine has a foundation. A profiling device is disposed on the foundation. The profiling device swings leftward and rightward at the same height relative to the foundation. An upright post is disposed at one end of the profiling device and has a terminal portion extending upward. A workbench is pivotally connected to the terminal portion of the upright post. The workbench tilts vertically and swings horizontally relative to the upright post. Therefore, the all-directional profiling machine performs a multi-angle profiling cutting process without demounting a workpiece repeatedly such that the processing of oblique surfaces is quicker, simpler and more precise, so as to not only meet various requirements of different processing angles but also feature enhanced processing efficiency.

A facer for use in preparing the opposed ends of polyolefin pipes for fusion into a pipeline has a pair of cutting wheels which rotate in unison. A controller causes the cutting wheels to trace and face the pipe end walls in a closed loop path.
