I did discover that it mills cast iron surprisingly well and much better than aluminum. Is this normal? I slotted for about 3 hours on a single 2mm carbide end mill running 10k rpm on the spindle. 220mm/m and .5mm doc without seeming to dull the bit or have any issue. The machine does not seem to cut aluminum as well. No air on the chips and no dust collection. What gives?
