These types of lubricants are sprayed in large quantities onto the machining area during metal processing, usually by continuous rinsing. This makes it impossible to flexibly adjust the oil and water supply according to the working conditions of the workpiece. Moreover, the large amount of cooling medium used leads to waste and easily generates oil fumes and oil stains, affecting the working environment. Utility Model Content

The outlet of the diaphragm pump 13 is connected to the inlet of a second water tank 14 via a water supply pipeline. The outlet of the second water tank 14 is connected to the inlet of a water circuit solenoid valve 15 via a water supply pipeline. The outlet of the water circuit solenoid valve 15 is connected to a second pump body 16 via a water supply pipeline.

[0022] The second pump body 16 in the water supply assembly is also a peristaltic pump, equipped with four inlet ends and four outlet ends. A second pipeline splitter is connected between the water circuit solenoid valve 15 and the second pump body 16 via a water supply pipeline.

[0027] When the aforementioned three-phase micro-lubrication device is in operation, it is activated when the machine tool is powered on. The operator sets the corresponding operating parameters in the PLC controller, for example, setting the water output to 10ml / h and the oil output to 200ml / h. After setting the oil and water output parameters, the operator clicks "Start." At this time, a peristaltic pump in the oil circuit and another in the water circuit will output oil and water according to the set parameters. The oil, water, and gas are connected to the atomizing spray gun through pipelines. The oil and water continue to advance inside the atomizing spray gun, forming water-in-oil droplets, which are finally sprayed onto the processing area through the nozzle of the atomizing spray gun in the form of oil-in-gas and water-in-oil droplets.

[0028] Therefore, the technical solution of this application can digitally and flexibly adjust the oil and water supply according to the working conditions of the workpiece, avoiding waste of lubricating oil and water resources and effectively reducing production costs. At the same time, the various components inside the main unit housing 1 are assembled in a modular manner, which not only allows for flexible adjustment of the number of oil and water supply output channels, but also makes them easy to disassemble and install, facilitating later maintenance and replacement.

[0029] In addition to the above embodiments, this utility model may have other implementation methods; all technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
