If you wish to mill aluminium sheets on the DamenCNC Haase AL series, we advise to add this option. The Fogbuster is the best coolant system we have found so far. The dual head is perfect, since you can spray the coolant under 2 angles at the cutter.
If you are milling plastics or other products that do not require coolant, it is also possible to close the coolant adjustment screw, and only spray air. This can help to remove chips from your product.
