ABSTRACT:
An apparatus for forming input and output electrodes on the outer peripheral surface of a dielectric block coated with an electrically conductive film includes a holder for holding the block, a cutting tool with cutting surfaces, and a compression pump. Mobile tables supporting the holder and the cutting tool are controlled to cause the cutting surfaces to come in contact with a specified area on the outer peripheral surface of the block. Cutting water mixed with abrasive grains is projected by the compression pump onto the specified area, and ultrasonic vibrations generated by a vibration generator and amplified by an amplifier horn are transmitted to the cutter, causing a portion of the conductive film to be removed from a frame-shaped area, leaving an isolated piece of the conductive film separated from the remainder of the film to serve as an electrode.
