We have a new haas VF6 machining center and have a haas hrt 450 indexer. My question is does the indexers brake need to be on when i am machining with just the indexer rotating? i am a little confused on what the manual is saying regarding this. Also i am looking for a program example. I am milling the diameter of a disk just positioning the endmill, then rotating the indexer. With the indexer table parralel to the machine table.
