129 forum posts 13 photos | Hi, I am turning down a piece of aluminium round stock, the chips that are coming of are like grains of sand ? i have tried different speeds and inserts but the chips remain the same. I notice on the end it is coded red so my question is this can anyone suggest what grade of aluminium this might be ? |
