The present invention relates to a two-fluid mixing nozzle which mixes and sprays a cutting oil and compressed air in a machine tool or a cutting machine, such as a CNC. The two-fluid mixing nozzle according to the present invention is characterized in that a spraying surface (11) of a nozzle body (10) is inclined to be perpendicular to the spraying angle (a) of a gas-liquid mixed fluid sprayed onto a processed part of a workpiece (100) from a spraying hole (31) of a nozzle cap (30), a pocket (12) is perforated at the center of the spraying surface (11) of the nozzle body (10), a supply hole of compressed air (13) and a supply hole of liquid (14) are connected to each other, and a mixing guide member (20) and the nozzle cap (30) are mounted on the pocket (12), and multiple leading grooves (22) are formed on the circumference of a crown-shaped part (21) of the mixing guide member (20), so liquid supplied to the inside of the crown-shaped part (21) through the leading grooves (22) is mixed with the compressed air sprayed from a discharge tube part (23) of the crown-shaped part (21) and the gas-liquid mixed fluid is sprayed outside through the spraying hole (31) of the nozzle cap (30). 본 발명은 CNC 등과 같은 공작기계 또는 절삭기계에서 절삭유와 압축공기를 혼합하여 분사하는 이류체 혼합노즐에 관한 것이다. 본 발명에 따른 이류체 혼합노즐은 노즐캡(30)의 분사구멍(31)에서 공작물(100)의 가공부위로 분사되는 기액혼합유체의 분사각(a)과 노즐바디(10)의 분사면(11)이 수직을 이루도록, 노즐 바디(10)의 분사면(11)이 경사지게 형성되고, 노즐바디(10)의 분사면(11) 중앙에 포켓(12)이 천공되고, 포켓(12)에 압축공기 공급구멍(13)과 액체 공급구멍(14)이 각각 연결되고, 포켓(12)에 혼합 가이드 부재(20)와 노즐캡(30)이 장착됨으로써, 혼합 가이드 부재(20)의 크라운 형상부(21)의 둘레에 다수개의 유도홈(22)이 형성되어, 유도홈(22)을 통해 크라운 형상부(21)의 내부로 공급되는 액체가 크라운 형상부(21)의 토출관부(23)에서 분사되는 압축공기와 만나 혼합되고, 기액혼합유체가 노즐캡(30)의 분사구멍(31)을 통해 외부로 분사되는 것을 특징으로 한다.
