ABSTRACT:
A planetary milling machine employs concentric inner drive tubes within a housing, eccentric cam means on one such tube and a motorized spindle unit in an orbitally adapted carrier in the housing which has cam follower means inter engaged with the cam means such that with both tubes constantly rotating and with one tube driving the carrier, a speed differential between the two tubes can be employed to establish the desired orbital relation of the spindle unit to a central working axis of the machine.
