Abstract
In a method for producing a water jet (45) that contains abrasive and emerges under high pressure from a nozzle (44), 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 (34) containing abrasive and water is provided at normal pressure, in a second step the provided abrasive suspension (34) is brought to a working pressure that is greatly above normal pressure, and in a third step a water jet (45) containing abrasive is produced, with a nozzle (44), from the abrasive suspension (34) that is under the working pressure.
