Abstract
A planetary machining apparatus comprises a rotor and one or more drive spindle assemblies mounted thereon. Each drive spindle assembly includes a rotary spindle support mounted for rotation on the rotor about an axis parallel to and radially spaced from the rotor axis, a drive spindle eccentrically mounted on the spindle support for rotation about an axis radially spaced from the spindle support axis, and a machining element mounted on the drive spindle. A pair of bidirectional hydraulic motors are mounted on the rotor in operative engagement with the spindle supports for angularly adjusting the spindle supports to effect a radial displacement of the drive spindles and the machining elements relative to the axis of the rotor. A control arrangement including a rotary fluid distributor is provided for selectively operating the hydraulic motors during rotor rotation.
