Claim:
A machine tool comprising: a bed; a table arranged on the bed, for carrying a workpiece; a moving component disposed on the bed and provided free to travel at least on a horizontal first axis that is front-to-rear oriented; a main spindle supported by the moving component to rotate freely on the main spindle axial center, for holding a tool; a feed mechanism for shifting the table and the moving component relative to each other along three orthogonal axes including the first axis, to shift the table and the main spindle relative to each other within a machining area; and a machining-area-covering cover for covering a front side of the machining area with a front cover and covering a top side of the machining area with a first top cover; wherein the front cover is provided on the front side of the bed and is furnished with a door that opens and closes traveling along a horizontal second axis perpendicular to the first axis, and the first top cover is configured with a first end connected shiftably along the second axis to the front side of the moving component, and with a second end connected extensibly and retractably along the first axis to the top part of the front-cover door, therein being configured for permitting first-axis-directed movement of the moving component.
