<p>A machining arrangement increases the utilisation capacity of devices which execute similar machining phases and arranged on predetermined curves (5) (such as gear hobbing) in the direction of a larger machining diameter (14), the main dimensions of the machining remaining the same. To this effect, the work-pieces (1) of which the largest machining diameter (14) is not concentrically tensionable anymore with respect to the receiving center (2) of the work piece (dividing head) are excentrically arranged with respect to the center (2). Furthermore, the tool (7) is directed towards work positions (6) situated each time on different coordinates (y, z) by means of at least three linear motor elements (10, 12, 17) which cooperate, are arranged crosswise and are simultaneousy controlled by a computer program according to the predetermined curve (5). Therefore, it becomes possible to machine segment-like or bar-like work-pieces (7), in addition to wheels, within machining diameter limits and according to predetermined curves (5). In a period of fall of the demand for large parts, the same machine may be rationally used for machining smaller (wheels) series parts.</p> |
