    Default Infeed centerless grinding questions

    Hey guys, new member here hoping for some advice. I usually do through-feed grinding, but was recently asked to infeed some longer parts on a van norman centerless grinder. They are about 24"s long, with 3 different OD's on them. My question is, how do I keep the different OD's concentric with each other? I don't mind the run out on centers, but I need the different OD's to all be concentric with each other. Any advice would be greatly appreciated.

    I don't see any way to do that. The centerless makes wonderfully round parts but concentricity is not in the cards unless all diameters are ground at once. Somewhere out there there might be a machine with 24" width capability but I've never heard of one.

    There is, it is a Lidkoping CL-46 20" od 24" wide machine but finding one here is not easy and they get pretty pricey. I don't think that the OP can keep the concentricity either.

    If you are locked in to centerless on these you need to find someone who has one of those and be real nice. Like your ass belongs to him.
