The invention relates to an apparatus and a method for removing compressor blades, particularly to apparatus and method for removing a blade (305) from a dovetailed slot in a wheel (215) of a rotating machine. At least one device (220) is adapted to apply a pushing force on a first surface of a blade. A turntable (210) for supporting the wheel has indexing capability to advance the wheel by a predetermined amount. The device can be used to remove one or more blades from the wheel.
