Process to Fixing Foaming Machine

Machine foaming immediately upon coolant discharge from spindle and wash down. 

  1. Check concentration with Refractometer.
     
  2. Take retain sample of coolant from spindle and shake it up; the foam breaks in more than 8 seconds.
     
  3. Treat the retain sample with a drop of defoamer from quart bottle; the foam breaks in 5-8 seconds.
     
  4. Remove, inspect and clean all the filters; they may have plugged up from oils or shipping protection ingredients; or enough chips have collected to possibly act as a barrier and cause the foam to strip out.
  5. Turn on the wash down and disperse the quart bottle in the machine, or do same at spindle; disperse very slowly.
  6. Take retain from the spindle; observe the foam breaking in 5 seconds.
  7. Add water or coolant to the machine to bring the coolant to 10%.
