Abstract:
A machine tool, for machining a workpiece by a relative displacement between the workpiece and a tool in three axial directions X, Y, and Z, comprising:a bed forming a base;a table, on which the workpiece is secured, which is guided and movable on the bed in at least a horizontal direction by a pair of opposed table-guides;a spindle head having a main spindle for mounting the tool, which is relatively movable with respect to the table;a U-shaped chip receiver forming a center trough for chips provided under the table and extending in the table moving direction;two covers, each of which covers one table-guide for the pair of opposed table guides, for guiding and gathering chips into the chip receiver; andan adjustable cover composed of partially overlapping, relatively movable cover plates and defining a rear surface of a splash guard opposed to a frontal surface of a movable column, wherein said adjustable cover has a through-hole through which the spindle head or the movable column extends into the machining zone inside the splash guard, said through-hole being able to change its position so as to follow the movement of the spindle head in leftward and rightward directions or in upward and downward directions.
