ABSTRACT:
In a machine tool of the present invention, a spindle head rotatably supports a vertical tool spindle. On the spindle head base, a guide mechanism is provided so as to guide the spindle head in mutually orthogonal first and second horizontal directions and in a vertical direction. A workpiece is supported on a workpiece supporting base provided at a front side of the spindle head base. The workpiece is surrounded with a side cover assembly on the workpiece support base so as to define a machining area therewithin. The upper end of the side cover assembly is covered with a top cover assembly. The top cover assembly has a spindle hole through which a nose portion of the spindle head passes so as to permit the tool spindle to reach the machining area, and is flexibly operable to follow the movements of the spindle head in the first and second horizontal directions.
