ABSTRACT:
A machine tool comprising at least one vertically reciprocating tool, such as a punch or the like, and a laser beam cutting device for cutting a workpiece thereunder positioned by a coordinate table movable in a plane in two directions normal to each other, in which the laser beam cutting head of the laser beam cutting device and the protecting tube connecting the laser beam cutting device with a laser generator are mounted on an overhang beam carrying the laser beam cutting head at one end thereof above a workpiece on the table and in which the overhang beam is connected at the other end thereof to a sleeve which is turnable about the axis of an uprgiht column which is independent and disassociated of a machine tool body supporting said reciprocating tool so that vibrations created during operation of the reciprocating tool are not transmitted to the laser beam cutting head.
