There is a lot of talk online about the internal coolant flow in these Chinese tubes and I just wanted to separate fact from fiction.
A user on cnczone mentioned that there is metal (I believe they said aluminum) in the tubes which actually comes into contact with the liquid coolant. I don’t see how this can be true as the coolant would then become charged with 22KV.
Someone on CNCZone said that the beam actually passes through the coolant briefly; now this just seems crazy to me. I can’t find any places where the laser beam would actually pass through the coolant.
Again, I don’t believe either of these is true but I figured I would ask just to make sure I’m not missing something.
