Processing machine for use in the manufacture of a coated brake disc having a main body having a rotationally symmetrical mass distribution with respect to a rotational axis of the brake disc and comprising a central hub portion and an annular brake portion surrounding the hub portion, wherein the brake portion has two axially opposite surfaces, each bearing a rotationally symmetrical functional layer with respect to the rotational axis, the free surface of which is formed as the friction surface of the brake disc, wherein the processing machine comprises: a machine base; a transport system having a spindle carrier unit which is movable relative to the machine base and which carries at least one workpiece spindle which is rotatably mounted relative to the spindle carrier unit about a spindle rotation axis and has a workpiece holding device which is designed in such a way that a main body received on the workpiece holding device can be rotated substantially around the rotation axis coaxial with respect to the spindle rotation axis when the workpiece spindle is rotated; a plurality of workstations (ST1 to ST4) arranged along a transport path and accessible by the workpiece spindle, comprising a loading station (110, ST1) and at least one processing station (120-1, 120-2) with at least one processing unit for processing at least one side of the brake portion; a drive system with at least one spindle drive for generating rotary movements of the workpiece spindle around the spindle rotation axis in response to control signals from a control unit, characterized in that the drive system and the control unit are configured in such a way that, after fastening a brake disc to the workpiece holding device in the loading station before the processing station is reached, a workpiece spindle can be set in rotation with increasing speed by means of an assigned spindle drive in such a way that the workpiece received on the workpiece spindle can be moved rotationally into the processing position at an entry speed. a machine base; a transport system having a spindle carrier unit which is movable relative to the machine base and which carries at least one workpiece spindle which is rotatably mounted relative to the spindle carrier unit about a spindle rotation axis and has a workpiece holding device which is designed in such a way that a main body received on the workpiece holding device can be rotated substantially around the rotation axis coaxial with respect to the spindle rotation axis when the workpiece spindle is rotated; a plurality of workstations (ST1 to ST4) arranged along a transport path and accessible by the workpiece spindle, comprising a loading station (110, ST1) and at least one processing station (120-1, 120-2) with at least one processing unit for processing at least one side of the brake portion; a drive system with at least one spindle drive for generating rotary movements of the workpiece spindle around the spindle rotation axis in response to control signals from a control unit, characterized in that the drive system and the control unit are configured in such a way that, after fastening a brake disc to the workpiece holding device in the loading station before the processing station is reached, a workpiece spindle can be set in rotation with increasing speed by means of an assigned spindle drive in such a way that the workpiece received on the workpiece spindle can be moved rotationally into the processing position at an entry speed.
