Abstract (en)
[origin: WO2011004085A1] The invention relates to a method for cutting a material, in which said material is cut using a cutting jet at a pressure of at least 100 bars, characterised in that the cutting jet consists of a mixture of at least one first compound in liquid form at a cryogenic temperature of less than -100°C and solid abrasive particles consisting of at least one abrasive material with a hardness number of at least 6 Mohs. The invention also relates to a device for implementing the method, which includes a focusing gun and a mixing chamber. The hardness of the material that forms all or part of the focusing gun is higher than the hardness of the solid abrasive particles used.
