  • What is this really, and what does it do?

    It says it's a tool cutter grinder, but it looks like nothing i have ever seen.

    ebay grinder?

    Ill guess its for turning long bars or maybe tubes into OD ground lengths, which are cut off to the right length and then deposited down the chute on the RHS.

    hope someone really knows, Im intrigued

      I have used a grinder that was almost identical to this, but about 1/4 the size. Ours was used to cut and grind to length the hardened steel ejector pins that are used in injection molds. You slid the pin against a micrometer adjustable stop and the pin was cut by the abrasive wheel and then sized by the grinding wheel. Pretty specialized device.

        Centreless grinding?

        George,

        it seems to me that the grinder might have been a "centre-less" grinder to match those criteria.

        Is that so?

          It is basically a precision chop saw, rather than a centerless grinder.

            What George said.

            Although I've never seen one setup to take such long material. Plus, there should be some kind of work holder or rest near cutting/grinding area.

            Punch grinders are the same, but generally without a cutoff wheel.

            Notice the adjustment dial at the back side for the grinding wheel only.

              I can see that now, seems like an overly specialized tool.

                It looks like a precision cutoff grinder for extremely thinwall tubing. Any other method involving a toothed blade would collapse the tube.
