In order to comply with the development direction of green manufacturing, minimum quantity lubrication (MQL)technology gradually replaces the traditional pouring technology. The prerequisite for applying this technology is to design an excellent minimum quantity lubrication device. Based on the research of minimum quantity lubrication technology and common domestic minimum quantity lubrication devices, a new type of minimum quantity lubrication device was designed,and the design principles of precision atomization nozzles, sealed cylinders, lubricating oil circulation system were elaborated.Finally,it was compared with dry cutting and traditional minimum quantity lubrication device through cutting experiments.The experimental results show the applicability of this device in industrial cutting field, and it has a better cutting effect than traditional minimum quantity lubrication devices.
