Et refrigerationem apparatus instrumentum sprayer, per Gas Instet et Liquid Iniectio, Airflow per Gas tubus in interiori in aere fluunt ad interiorem, cum in Guide Black Tenuus et in Gas in Guide et in Retactum fluxus, et in Gas in Guide et in Duide fluxus, in Gas et in Guide, in Guide Flow et in Gas, in GOF Ad gap socors, et exterior imbre, et influunt de liquido in liquido CERVIX oris, per gas pressura ad dispersere liquidum ad caligo, ita ut consequi maiores in workpiece effectus. The liquid flowing out of the nozzle is dispersed to a mist by the pressure of the gas and sprayed onto the workpiece, thus achieving a larger area for a small amount of liquid to be dispersed by the gas, saving the use of liquid and enhancing the cooling effect, as well as solving the problem of a large amount of water accumulation in the machine tool and making the machining chips easier to be sucked away and safer.
