  • what is this - grinder???????

    this is another one of my "yard sale finds". the guy basically gave it to me at the end of the day because no one wanted it and he wanted it out of his yard. so what type of grinder is it and can i make some use of it? both motors work and the indexing unit in the first photo turns smoothly. what type of taper is that on the spindle nose? i have the bolts to bolt the item in the first photo back onto the mess in the second photo, but i am at a loss as to what to do after that. the grinding head arrangement in the second photo is homemade, but it looks like it should work (somehow). any idea what brand this would have originally been? it is QUITE heavy.

    Life is good. That is most of a tool & cutter grinder.

    The first motor and tailstock assembly is a power center for circular grinding. Mainly for doing reamers and such.

    With a little cleaning up, the second photo has the makings of a good machine. Nice find.

      The external taper looks a little like an early Hardinge taper. If it is, the internal taper may take a 3c, 4c, or 5c collet directly. (See link)

        I'm not sure, but the spindle on the workhead in the first picture looks like a Hardinge taper to me.

            you guys are good! it sure looks like that Hardinge taper. i guess i will weld up a stand for it and add it to my list of winter projects. sometime around december you folks will probably see some more questions on it.

              Andy. I have a spindle just like that one minus the base and tailstock. The taper nose is like a Hardinge/Cataract only a little smaller in the OD. It has no name or numbers anywhere on the spindle portion. Does yours have some identification on the base or tailstock (or maybe motor as mine had a different motor when I got it). I'm always on the lookout for any attachments for that smaller taper nose. So far no luck.

                Hmm...
                Not sure but I do indeed recognize the Hardinge Taper on the headstock. At first I thought it to be a second operation lathe but think now it is some sort of tool and cutter grinder. Lets see what "the boys" think it to be.
