DEVICE AND METHOD FOR MACHINING A SOLID MATERIAL USING A WATER JET

摘要

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 strikes the solid material. In this case, a medium which is gaseous under standard conditions is dissolved in water in a mixing step under pressure (1-150 bar) and is then compressed to 1000-4500 bar and forced through a nozzle, under conditions which allow the dissolved gaseous medium to bubble out after leaving the nozzle, wherein the heat of solution is extracted from the water and the ice crystals are formed.
