Abstract

PURPOSE:To promote the improvement of efficiency by providing a number of supports with a predetermined space in a holder in parallel with the axial center and supporting each cutter to each support, in the case of a device which holds the cutter by a pair of spindles cutting the internal surface of a workpiece. CONSTITUTION:After a workpiece 1 is positioned, holding a cutter 4 by spindles 17, 21 to be rotated, the workpiece 1 is roughed in its right side internal surface 2a by advancing a unit 24 and retracting a unit 25. Next reversely actuating the units 24, 25, after a left side internal surface 2b is roughed, returning the cutter 4 to the initial position, the spindles 17, 21 are detached from the cutter 4 by stopping rotation of a driving motor 26. And moving a holder 8 in the direction of a Z-axis by a cylinder, a cutter 5 is placed with its axial center in parallel with the spindle 17, finishing the right and left side internal surfaces 2a, 2b. Thus enabling the time to be reduced for setting the cutters 4, 5, work efficiency is improved.
