    Might be worth experimenting with faster speeds for better finish... 160 sounds slow for 12mm stock (what material?).

    EDIT re speeds I should read your post fully before opening my gob!

    Incidentally if you are machining a fairly long ballscrew or whatever you might want to make sure the back end of it is supported to stop it flailing around - a collar type arrangement to plug into the back of the spindle hole would do it.
