Abstract
A machine tool capable of reducing the lateral width of the upper part thereof by reducing the lateral width of a bed (1) while machining through the same lateral moving distance of a spindle (10) as before, comprising longitudinal guide rails (2) installed on the bed (1), a slide (3) installed through the guide rails (2) movably in a longitudinal direction, a column (6) movable in vertical direction, wherein first cover plates (25) are fixed at the right and left sides of a vertical moving route for the spindle (10), side cover plates (26) are installed continuously with the outer end edges of the first cover plates (25) so as to be turnable rearward, a second cover plate (32) is installed at the front sides of the first cover plates (25) and the side cover plates (26) integrally with the slide (3) so as to cover the front side of the moving range of the column (6), and a shielded machining space (SK) is formed at the front of the second cover plate (32).
