Vertical machine tool with a movable main spindle

摘要

A vertical lathe (1) is provided with a base (3), a main spindle (4), a headstock (7), a tool rest (8) and a splash guard (9). The headstock (7) is movable in a Z-axis direction and an X-axis direction and grips a bar workpiece (6) by a chuck (5). The bar workpiece (6) is machined by moving the headstock (7) and a tool (11). A part which has been subjected to the machining is cut by a cut-off tool (11a) as a machined workpiece (6a). The lathe (1) has a supporting means (100), provided above the headstock (7), for supporting an upper end of the bar workpiece (6) and a transfer means (2) for receiving the machined workpiece (6a) from the chuck (5) and for transferring the machined workpiece (6a) to an outside of a machining area (13).
