MACHINE TOOL WITH INDEX MEANS

摘要

A machine tool body (1) is equipped with a spindle (9) which can move vertically along the Y axis. A first table (14) on a bed (10) of the machine tool body (1) is movable horizonally in the Z direction and can move toward the tool (11) held by the spindle (9). A second table (15) set on the first table (14) can move in a horizontal direction at a right angle to the moving direction of the first table (14). A first rotary table (16) set on the second table 15 can be indexed about the rotation axis (RO) and has an extension portion (17) extending upwardly. The second rotary table (19) set on a side surface (16) of the extension portion (17) can be indexed about a rotation axis (QO) while it holds fixedly a workpiece (W). A workpiece feeding means (4) is used to load a workpiece (W) onto the second rotary table (19) and after machining thereof unload each workpiece (W) for the second rotary table (19).
