DOUBLE-SIDE MULTIPLE SPINDLE MACHINE, AND MANUFACTURING METHOD USING DOUBLE-SIDE MULTIPLE SPINDLE MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a double-side multiple spindle machine capable of suppressing the generation of chattering.;SOLUTION: A double-side multiple spindle machine 1 is equipped with a first machining unit 2 for machining one surface of work W, and a second machining unit 3 for machining the other surface of the work W. The first machining unit 2 and the second machining unit 3 successively machine the work W. The second machining unit 3 has an abutting unit 10 abutting on the work vibrated in a thickness direction by the machining of the first machining unit 2. The abutting unit 10 is installed between a plurality of tools of the second machining unit 3 and equipped with: a cylinder 11 having a rod 12b capable of moving backward/forward to the other surface; and a pad 14 provided on a tip end side of the rod 12b. The pad 14 is projected out to the other surface side more than the plurality of tools of the second machining unit 3 to abut on the other surface by the forward movement of the rod 12b, and retracted into between the plurality of tools by the backward movement of the rod 12b.;COPYRIGHT: (C)2015,JPO&INPIT
