The present invention provides a machine tool capable of suppressing cost increase of a cover even when a long workpiece is machined. A machining unitby which the spindleis supported to be movable in X-axis, Y-axis, and Z-axis directions relative to the machining table; and a shielding mechanismprovided in said machining unitto prevent chips and coolant from scattering out of a machining area.

Machine tool

Machine tool having a bed, a table arranged on the bed, a first saddle provided free to travel back and forth, a second saddle supported on the first saddle and provided free to travel side to side, a spindle head provided free to travel perpendicularly on the second saddle, a main spindle situated above the table and by the spindle head supported free to rotate on its center axis, a front cover provided on the front side of the bed and furnished with doors that open and close sideways, and top covers configured with one end sideways shiftably connected to the front side of the first saddle, and with another end connected extensibly/retractably to the top of the front-cover doors, therein being configured for permitting back-and-forth-directed movement of the first saddle.

The present invention provides a machine tool realizing high-speed movement of a spindle and thus reducing the machining time without any increase in size of the whole machine. A machining unitby which a spindlewith a tool T attached thereto is supported to be relatively movable in X-axis, Y-axis, and Z-axis directions is mounted on a long bedhaving a plurality of machining areas ato aarranged in one direction, and the machining unitis movable in the arrangement direction of the machining areas.
