Abstract: Disclosed is an adjustable ultrasonic micro-jet nozzle array with minimal quantity lubrication, relating to cooling of machining. The array-type nozzle includes an inlet conduit, a recycle conduit and a cooling body having a microjet ejection assembly and a recycling assembly. The cooling body includes a microjet ejection chamber which is closed. The inlet conduit is provided at a top of the cooling body and communicates with the microjet ejection chamber. The recycle conduit is located in the microjet ejection chamber, and connects the recycling assembly and an external vacuum machine. The adjustable ultrasonic micro jet nozzle array of the present invention has the advantages of simple structure and being convenient to use. A flow rate of trace cooling fluid is increased to improve the cooling and lubricating effect. A cooling fluid mist is recycled by the vacuum suction to reduce the consumption of the lubricating fluid while ensuring the cooling effect.
