How to Optimize Aluminum Grinding and Cutting
One practice to reduce aluminum metal loading is the application of wax onto a grinding wheel, which delays the onset of metal loading. By applying a slippery substance on the wheel's surface, it temporarily makes it harder for the aluminum chips to stick. However, as the wheel is used, the wax wears away and will need to be reapplied.
