Metal pieces such as blooms, continuously cast billets and cogged ingots, are cut by a deep-frozen, liquid cutting medium, in particular liquid oxygen, exiting from a nozzle at high pressure. The workpiece is moved in the longitudinal direction and the nozzle is moved in the crosswise direction at an acute setting angle with respect to the longitudinal direction. As a result, it is possible to dispense with the travel segment of the workpiece and of the cutting nozzle in the longitudinal direction of the workpiece during the cutting process.
