A positioning device (1) of a processing module of a cable processing machine for finishing a cable. The positioning device (1) includes a first displacing device (10) for displacing the processing module relative to the cable to be processed along a first, in particular horizontal axis (x) transversely, preferably perpendicularly to the longitudinal axis (L) of the cable to be processed and a second displacing device (20) for displacing the processing module relative to the cable to be processed along a second, in particular vertical axis (z) transversely, preferably perpendicularly to the longitudinal axis (L) of the cable to be processed and transversely, preferably perpendicular to the first axis (x). A processing module and a cable processing machine having at least one such positioning device (1).
