Abstract (en)
[origin: WO2020212187A1] Method for machining workpieces, employing an intake of a cryogenic fluid in the machining zone (1), characterized in that use is made, on the line connecting the fluid source to the machining tool (5) in the machining zone, of a valve able to self-regulate its degree of opening according to the pressure required downstream thereof, making it possible to deliver a fixed and adjustable pressure, and therefore a fixed adjustable flow, to the machining tool irrespective of the tool used, and therefore the number of orifices and the diameter of the fluid ejection orifices characterizing the tool in question.
