I needed a lubrication system for my lathe but didn't want a fog system to avoid aerosols. I decided to make a system that uses a garden sprayer that function as "fluid pump" and a car fuel injector to regulate the flow. A small ESP32-C3 micro computer control's the flow by pulsing the injector. You could wire wrap that whole thing or control the injection valve directly by your CNC controller using only a solid state relay.
The build cost are about 30 € (30 US $).You can download the design, schematics and the firmware on Git. A video showing the system in action and explaining how it is used is available on YouTube
.
I am going to use the same same system on my CNC router. There I will use compressed air to blast the chips away and the MQL will supply the lubrication in a controlled way. The firmware is already done and bench tested and I will build a system as soon as I find the time to do it.
