The invention concerns a method for producing a water jet that contains abrasive and emerges under high pressure from a nozzle Uninterrupted operation with, at the same time, greater working performance and lower costs is made possible in that in a first step an abrasive suspension containing abrasive and water is provided at normal pressure, in a second step the provided abrasive suspension is brought to a working pressure that is greatly above normal pressure, and in a third step a water jet containing abrasive is produced, by means of a nozzle , from the abrasive suspension that: is under the working pressure.
