New CNC Mill on the horizon

[Boyan Silyavski]

Air supply pressurizes at 2 bar the container which is just about right for the air flow needed, so no need for super precise separate regulator at the end, one normal regulator with filter before the container is enough. There is a second precise valve that regulates the coolant flow in the nozzle. 4mm OD tubes each are enough for the flow both for air and coolant. 0.8-1.5 mm nozzle at the end depending what exactly you want to do, i would say 1mm is perfect flow wise and control wise. Polycarbonate containers are rated 6 bars usually. the precise air flow formation depends on the outside angle + inside angle combination /of the nozzle tip/.

Hope that helps and clears the basic principles of the design.
