What do you use a Spindexer for?

A week or so back I got a simple email from an old friend, he asked "do you want a spindexer?" I said perhaps, what is it for? He says it clamps things in a 5c collet and spins them so I replied sure, thinking it was something like a speed lathe or something.
Well it showed up yesterday, shiny new in the box with all its stuff, I see them for sale but not much about what to do with it.
Who is using one and what do you use it for?

I bought mine new from Enco around 1980 because it looked useful. The only job that I can recall doing on it in 40+ years was to clamp it on my vertical mill and engrave a few fine lines at 1 degree intervals on some cutter grinder attachments I made. It was just the right tool for that job. The spindle lock is not robust enough for serious milling. Anyway, I have real dividing and indexing heads for the heavier milling jobs.

I have never had occasion to use the spindexer on my surface grinder, though I could imagine it grinding a pilot on a reamer or similar work.

I was kind of thinking special cutters on a surface grinder would be the main thing, I didn't realize in could index, I recon I had best open it up and look at it better. Believe it or not I have done most of that in a dewalt cordless drill to get me by until the factory ones show up.
thanks

We are a company with three toolmakers, and we have two spindexes.

We use them to make form punches, pierce punches, blankout punches, grind in buttons and many more things.

They are VERY accurate, if you wish to make stuff that is concentrically perfect. Our spindexes hold very tight tolerances.(.0002 on concentricity).

Don't use this device with coolant, it will ruin it quickly. Also, store it in a place devoid of moisture to prevent rusting. I also recommend removing the belt until you need it.

I've got a couple of the cheap ones. I used to do a lot of 5C work, and the spindex went along with the mode.

They are great for drilling two holes at known angles to one another. Or milling features on round work. Little knobs , handles and the like.
If you have a good election of 5C collets, you will find the device useful.
If you don't have a complete set of collets, the thing will just gather dust , ...until that one job comes along.

I think you're referring to something more akin to a Harig Grind-All, yes? I have one of those too, it's a lot more sturdy and accurate than a regular spindex. At least the cheap imports anyway. I have one of those cheap imports and a nicer one made by Path Industries. That one I'd actually trust to do some pretty close work.

The $50 cheap-os should be looked at as KITS.

30 yrs ago I used it to make pun hes for prog dies.

Now it mostly gets used to modify std drills into specials.

A bit outside general shop use but I cut a "V" on the end/face of a round pin (Tantung G) I had to clamp small parts in. I could then swing a target radius when inserted into the spin-dex. This worked for putting a crown on a punch (stamping dies) that didn't have a slug eject pin. It could also be used with a diamond to dress a concave/convex radius on the wheel in a SG. All of these are a bit of a kludge but it's what I used before getting a Harig head and a Clearview dresser if the shop didn't have either. Most of the spin-dex I've seen aren't very stable for milling but they are useful for flats or what others have already posted.

I have 3 5C spin indexers. I rarely use them with a 5C collet though. Instead I have two 3" chucks. One 3 jaw scroll and one 4 jaw independent that I use on the indexer. I use this combination to cut wrench flats on items I make. They are fast to set up and use. I also have an 8" super spacer for bigger jobs and differential dividing heads for greater accuracy.

Guess I am a slower learner, then?

My one has been holding down a shelf for only ten years, prays at the usual high holy days for a surface grinder or a tool & cutter grinder to fall out of the sky.

Ain't been used ONCE.. yet.

Yes, I, too, have rotabs and a right decent Ellis Dividing head with the FULL set of extended plates, even.

Best of all, the Ellis is ALSO a "speed indexer", working either off the DH worm OR off a notched pate its DH side can custom make for itself.

And it DOES have a serious lock, option of stout thread-mount chuck or faceplate, and strong #9 B&S taper that can grab my extensive inventory of mill tooling.

LOVE the Ellis!

Even so, it is the low-profile rotab with #2 MT as sees more actual use. With a Jacobs chuck or ER collet on #2 MT tail, even.

I use ours every day in the surface grinder. (again, no coolant!)

I also have a grind-all but that is for different work, such as ovals, also extremely accurate.
