The tool support element (110) is movable with respect to the upper frame element (108) in an X-axis direction (104). The frame structure (102) is movable with respect to the base element (103), and with respect to a workpiece held between the lower and upper frame elements (107, 108), in a Y-axis direction (105). A CNC machine comprising the apparatus (101).

A tool cabinet includes a cabinet body having two guide rails and a routing space that is proximate to one of the guide rails, a working platform unit having a protective tube, two lifting units, a driving unit, and a power supply unit having a transmission wire. The working platform unit includes two extension members respectively slidable relative to the guide rails. Each lifting units includes a threaded rod extending through a respective extension member. The driving unit is disposed for driving rotation of the threaded rod of a respective one of the lifting units. The transmission wire has an end connected to the driving unit, and an opposite end extending through the protective tube into the routing space.

A machining device, in particular a grinding device, for the machining of slots in a component, in particular radially lying slots in a stationary blade carrier, with a base carrier, a clamping device, which is attached to the base carrier pivotably about a pivot axis and is designed to fix the base carrier on the component to be machined, a guiding rail, which is guided on the base carrier displaceably in a straight line in a guiding plane lying perpendicularly in relation to the pivot axis, and a tool holder head, which is held on the guiding rail pivotably about a rotation axis parallel to the pivot axis and carries fastening means for the attachment of a machining tool is provided.

An apparatus for precision shaving is provided. In one embodiment, the apparatus includes an endmill cutter, a base frame, and a motor adjacent to the base frame and having a shaft on one end. A coupler is positioned between the shaft and the endmill cutter. A positioning slide is housed within the base frame and a coupler frame and a first gear are fastened to the positioning slide. A second gear is adjacent to the first gear, the second gear having a set of first teeth and a set of second teeth positioned opposite the set of first teeth. The set of first teeth and the set of second teeth are separated by a gap.

A machine tool adapted to perform operations, for example, machining, on a surface of a part of large size is provided. The machine tool comprises a longitudinal rail and a transverse arm, orthogonal to the longitudinal rail, slidingly fastened at a first end to the longitudinal rail. A second end of the transverse arm is provided with a unit comprising a holding device enabling the unit to be held in position on the part during an operation. The transverse arm bearing a tool is thus precisely positioned on the part on which the operations are carried out.

A magnetic base for coupling a drill press to a ferromagnetic workpiece includes a ferromagnetic body having spaced, substantially parallel first and second rails. Each of the first and second rails includes a flat bottom surface engageable with the ferromagnetic workpiece. A coil is positioned between the first and second rails for generating a holding force on the ferromagnetic workpiece. The coil defines a central axis that is parallel with the bottom surface of each of the first and second rails.

A machine tool includes a frame with two opposite frame sections, a number of leg elements arranged on the frame, and a first carriage having a first linear axis. The first carriage is guided on the two opposite sections of the frame and is displaceable in a first direction. A second carriage of a second linear axis is guided on the first carriage and is displaceable in a second direction A tower element has a third linear axis, which is retained on the second carriage. A machining element is retained on the tower element and is displaceable in a third direction, and a tool spindle is arranged on the machining element for receiving a tool.

A method and apparatus for the refurbishment and repowering of wind turbines through the extension of existing installed blades so that they can catch more wind energy and therefore enable an increase in the overall average power output of the wind turbine.
