ABSTRACT:
Composable machine tool for chip removal, on major workpieces, within wide diameter and/or great length clearance holes, made up of a shaft (1) upon which a machine base, controlled by a first engine (50) for the rotation movement and by a second engine for the translation movement, upon which are mounted the design tool elements. On the shaft (1) two support bearings (15) are mounted on both sides of the workpiece (29), all have spokes (16) each of which have radial slots (17) in which the groups (33) are inserted, regulated and locked to tighten the workpiece, on the shaft, a hydraulic jack (34) is mounted at least on one side, at the two extremities of the shaft (1), two slotted shoulders (40) are mounted to allow the jack (34) to exert the necessary pressure to lock the workpiece.
