We have an inline feed centerless grinder that's capable of grinding 24 ft. bars and tubes. We are having trouble with lobing and/or hexing on the OD. We've realigned the jack plates to where the work piece is slightly above center. We've also dressed the Reg wheels. Just not sure if lobing and hexing has the same cause or not. We use 3-point v-anvil micrometers to check for lobing. Can we use the same method to check for hexing?
