Abstract

PURPOSE:To provide a work with a curved face formed with high accuracy and secure telescopic strokes of piezoelectric elements as well as of little elapsed change by supporting a displacement adjusting part and providing a jig main body with a minutely displaceable supporting part. CONSTITUTION:At the time of adjusting the height of a work mount 20 using a micro-head 22, a work 24 is mounted at the work mount 20 first, and then the height from the lower face 20d of the work mount 20 to the face to be machined of the work 24 is measured. The height from the lower face 2a of a correcting member 2 to the supporting part 14b of an intermediate member 14 is previously measured. The work mount 20 is then placed on a jig main body 1, and the micro-head 2 is adjusted by the necessary quantity. If a reference base of the same height as the height from the lower face 2a of the correcting member 2 to the supporting part 14 of the intermediate member 14 is prepared, the mount 20 adjusted in its height at the other place and placed on the jig main body 1 can be machined as it is.

Description
