US 12,691,525 B2 · Machining fluid and machining device using the same

Abstract

The present invention provides a machining fluid comprising a first phase fluid and a second phase fluid pressurized to be dissolved in the first phase fluid. The present invention further provides a machining device comprising an injecting head having a nozzle and a flow channel communicating with the nozzle for guiding the machining fluid to the nozzle injecting the machining fluid to an object. Alternatively, the present invention further provides a machining device comprising a light source for generating a laser beam and an injecting head having a nozzle and a flow channel communicating with the nozzle. The flow channel guides a machining fluid having a first phase fluid and a second phase fluid such that the machining fluid is injected to an object by the nozzle. The injecting head also receives the laser beam and guides the laser beam to the object through the nozzle.
