PURPOSE:To easily work necessary microcurved face and inclined face, by fitting the work to be polished to the tip of the lapping surface plate side of a lever, pressing the other end of the lever by the actuator of a piezoelectric element, etc., placed on a device base and making variable the abutting angle of the work opposed to the lapping surface plate. CONSTITUTION:A piezoelectric actuator 3 is arranged at the center of a device base 1, a vertical hole 4 is punched at the necessary position of a circumferential side, an L type lever 5 vertical part is inserted and the other part of the horizontal end side is placed on the piezoelectric actuator 3 upper end via a semi- spherical contact 6. A work 7 is stuck to the vertical part tip of this L type lever 5 and the necessary voltage is held by its impressing on the piezoelectric actuator 3, and then the work 7 is inclined at the necessary angle via the L type lever 5. When it is polished by rotating a lapping surface plate 20, for instance, a microinclined face is formed on the work 7. The work 7 can be formed in the necessary microcurved face by varying an impressing voltage while under this polishing. |
