CURVED SURFACE MACHINING MACHINE FOR WORK, CURVED SURFACE MACHINING METHOD, AND CURVED SURFACE MACHINING GRINDING WHEEL

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive curved surface machining machine for a work with a simple constitution which can execute various curved surface machining by a single curved surface machining machine. SOLUTION: A curved surface machining tool 13L mounted to a main spindle 11L has at least different kinds of the first tool 135 and the second tool 136, and a main spindle direction changing means 8 which enables the curved surface machining of the work W with the first tool 135 mounted to one main spindle 11L by making the main spindle 11L freely rotatable between the first position and the second position and making the main spindle 11L to be located at the first position, and enables the curved surface machining of the work W with the second tool 136 by making the main spindle to be located at the second position. The machining can be executed by providing a plurality of main spindles 11L, 11R and mounting different kinds of the curved surface machining tools 13R, 13L while switching the first tool 135 and the second tool 136.
