CNC Coolant Prevent Bacterial Growth With Ozonator
I've tried bubbler ozonator, but the problem is that the tanks are shallow and there's not enough time for good mixing into the coolant, so a lot of ozone escapes. It works, but it's not efficient. Also the stones get clogged over time.
Venturi and Static Mixer
The coolant lines on the Tormach and Haas TM-1 Mill and GT-10 lathes are both 0.5in ID
Based on pipe ID and glue rate approximation, the DN20 would be the correct size kit.
