Lobing vs Hexing on Centerless Grinder
Lobing vs Hexing on Centerless Grinder
(OP)
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?

You could try running the regulating wheel a little faster if that is an option, and setting your workpiece a little higher. Your infeed blade is fairly critical for good work. Also,what runs your regulating wheel, and is there any excessive slack in it (chain in particular)? This can cause roundness problems.
Good luck.
It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
