Abstract
A method of machining a solid material using a water jet discharging from a nozzle is specified, wherein the water jet contains ice crystals and impacts on the solid material. In this case, a medium which is gaseous under standard conditions is dissolved in water at a mixing stage under pressure (1-150 bar) and is then compressed to 1000-4500 bar and pressed through a nozzle, under conditions which allow the dissolved gaseous medium to bubble out after leaving the nozzle, whereupon the heat of solution is withdrawn from the water and the ice crystals are formed.
