It's not bad.. lock down the table, good sharp tool, lube....
on the other hand, if the rockers gall-up on the shafts, due to poor oiling, that is a completely different story.
It 'work hardens' the inside of the rocker where it galls up and it will destroy your hone. You have to get in there with a carbide bit and carefully knock out the galled up mess, then hone them.
