PURPOSE: To absorb the carrier and the work together simultaneously by absorbing the eccentric section of work through an absorption pad then applying a correcting/reinforcing board onto the rear face of thin unstable carrier fitted with a work and holding onto a plane.

CONSTITUTION: A drive sun gear 3 is arranged in the center of lapping machine while an internal gear 4 is arranged on the outercircumference. A planetary pinion supported on an annular lapping table 5 is gearing between them 3, 4. A compatible pad will absorb the eccentric section of work W0. The eccentric section of work can be absorbed through weak force of small pad while supported by a flexure correcting/reinforcing board from the rear of carriers P1WP5 fitted with thin work W0 thus to enable simultaneous adsorption and mounting/dismounting. Furthermore, a feed relay center 6 and containing relay center 7 are provided in the feed line and the containing line.
