PURPOSE:To obtain the captioned apparatus for versatile use which can treat a variety of works and requires the less replacing time by reducing the weight of the parts which require replacement. CONSTITUTION:A work 6 is rotatably supported onto a work driving apparatus of a chuck 7 and a tail stock 8. When the work on the first pin journal P1 is completed, a unit 3 is dividing-transferred to the second pin journal P2 by an NC apparatus. At the same time, the working units 4 and 5 for main journal are transferred, and one unit 4 dividing-fixes the work 6 at the position opposed to the first main journal J1. In this state, the working units 3 and 4 are advanced, and the second pin journal P2 and the first main journal J1 are lapping-working by each head apparatus. When preparation is necessary in the working units 3 and 4 because of the change of the work 6, each shoe-supporting base of the lapping head apparatus and a paper reel apparatus are replaced. |
