what is the machine, feed & speeds?
what type of coolant/
what type of holder & inserts.
I use to work with this stuff it does not not like small
feeds rates & depth of cut. Work Hardens like hell.
.015 min depth of cut when finishing.very very slow with carbide, , very fast with ceramic.
.050-.060 or more depth of cut with ceramic inserts.
depending on the rigity & horspower of your machine.
surface feed depends on the inserts.
