The invention relates to a minimum quantity lubrication supply system capable of automatically regulating the oil mist quantity for machine tool processing. The minimum quantity lubrication supply system comprises a gas conveying switch, at least one electromagnetic switch, a one-way valve, a flow rate control valve and an atomizing chamber, wherein the atomizing chamber contains cutting oil, the inner side wall of the top of the atomizing chamber is provided with at least two Venturi atomizing spray heads, the gas conveying switch is sequentially connected with one Venturi atomizing spray head through a gas conveying pipe, the gas conveying switch and the at least one electromagnetic valve are respectively and sequentially connected with the at least one Venturi atomizing spray head through a gas conveying pipe, the one-way valve and the flow rate control valve are sequentially connected through an oil liquid conveying pipeline, the bottom of the oil liquid conveying pipeline is communicated with the bottom of the atomizing chamber, the top of the flow rate control valve is connected with the at least two Venturi atomizing spray heads through an oil liquid conveying pipeline, and a baffle plate is fixedly arranged in the atomizing chamber. The minimum quantity lubrication supply system has the advantages that the structure is simple, the oil mist spraying quantity at the outlet part can be automatically regulated, and in addition, the oil mist can be simultaneously used for a plurality of machine tools.
