A machining system (SYS) for carrying out manufacturing in assembly lines is provided with individual tool units (WE1, WE 2, . . . , WEn) that each include a holding device (3-1, 3-2, . . . , 3-n). The individual tool units (WE1 , WE2, . . . , WEn) also comprise a position determination device (PBE1, PBE2, . . . , PBn) that determines the position of the tool unit along a retaining rail (4), in which the tool units are suspended. A control unit (ST1, ST2, . . . , STn) adjusts machining parameter sets according to the position of the tool units detected in the aforementioned manner. The retaining rail (4) is preferably provided in the form of a retaining rail, in which a conductor rail (11) and a data rail (10) are integrated whereby rendering trailing of the cable unnessary for conducting data communications and for supplying power. This configuration of tool units enables an easy and user-friendly execution of a simple reverse clocking and a simple expansion of the machining system with additional machining sections (BA1, BA2, . . . , Ban) and additional tool units (WE1, WE2, . . . , WEn).
