Abstract

A method for liquid-jet cutting, including a compressor unit (3), which compresses a liquid for producing a liquid jet, and a nozzle (10), which is connected to the compressor unit (3) and which has an outlet opening (11), through which the compressed liquid exits in the form of a liquid jet (14). The one flow of the compressed liquid to the outlet opening (11) is interrupted or enabled by an interrupting unit (8). The following steps are performed: compressing the liquid by the compressor unit (3), moving the outlet opening (11) toward a workpiece (15) to be processed until a processing distance (d) is reached, alternately enabling and interrupting the liquid jet (14) by the interrupting unit (8), wherein simultaneously the nozzle is moved in relation to the workpiece in a processing direction (22) and the pulse duration (tp; tp1; tp2) of the liquid jet is less than 1000 μs.
