I thought that if a rotor is "turned" than it was cut with a
stationary bit or cutter. If the rotor is "machined" than it
was cut down with a rotating head of some sort producing
those cool swirl patterns. My father said that helps
the pads break in faster. He also told me to
"rough up" the pads with 120 grit sand paper.
I make sure I get ALL grit off the pad before I install it.
