The double spindle machining center from RASOMA enables the machining of two work pieces simultaneously and is equipped with 2, optionally 4 or 6 drill spindles. With this machine, plenty of holes can be achieved at will. The automatic loading via a storage for raw parts is coupled to a work piece alignment to bring the different hole patterns into the brake discs position-oriented. In addition, a height-positioning of the brake disks takes place for the different heights. The thus determined height adjustment degrees are deposited in the control for the machining operation. For each type of brake disk, from the control side there is a machining program deposited for the corresponding hole pattern. A turning station connects the first clamping with the second clamping. Finished parts can be discharged by means of a roller conveyor.
