ABSTRACT:
A method of processing a scroll member having a spiral wrap and an end plate which is conducted by effecting a shaving on at least one side surface of the spiral wrap by a tool while applying to the tool both of an axial small force and an ultrasonic oscillation simultaneously. An apparatus is proposed which comprises a shaving tool having a spiral groove of the same configuration as the spiral wrap, and a cutting edge portion formed on at least one side edge of the groove over the entire length of the side edge. A tool supporting device supports the shaving tool, and a blank supporting device supports a scroll blank such that the scroll blank opposes to the shaving tool. A device is connected to the tool supporting means and is adapted to impart to the tool a pressing force necessary for effecting the shaving, and an ultrasonic oscillation generating device is adapted to impart an ultrasonic oscillation to one of the tool or the blank.
