Myford MG cylindrical grinders
The grinder I bought today is absolutely NOT CUTE. A Myford is cute, a SIP #1 or #2 jig bore is cute- a cylindrical grinder with a 36 inch wheel weighing I'm sure in excess of 20,000 pounds can only be classified as BAD! Yes sadly I'm running out of room. But it certainly won't be relegated to the great NW outdoors.

CNC Machining | OD/ID grinding with a lathe | Practical Machinist …
I have done some grinding on a CNC lathe with reasonable results. I only needed to grind a few parts, which were made from 8620, hardened to 62Rc. The parts required a little OD grinding, and some hairy internal grinding. As these were machine tool spindles with an HSK-60 taper they needed to be right on.

Old die grinder | The Hobby-Machinist
Then keep my eyes open for a die grinder with a 1/4" of dust on it for a good price. I have Grandpa's machinist tool chest packed with old school dial indicators, micrometers, inside diameter measuring thingys (pardon my lack of technical terms here) lathe and mill bits, all of it good old fashioned American made taps and dies.

Dumore Tool Post Grinder
Dumore Tool Post Grinder. 08-10-2016, 07:22 PM. I've never had a TP grinder, often thought it would be nice to have. Then, today, a friend gave me a small Dumore (Type 14) TP grinder.

How to align Tool Post Grinder?
I was thinking about building a tool post grinder when I found one at a tool swap. So I ground the jaws with a internal 1" course grinding wheel and then a fine 3/8" internal wheel. I "thought" the jaws looked really nice. I actually only ground down about .005" the hole was another 015". And then I tested the grind.

Rivett I.D. Grinder
The shop I subcontract with has been kicking around getting an I.D. grinder. We get a lot of parts that call out .0005 tol. on I.D.s and we have a great guy on the lathe that can do it on smaller, non-heat treated parts, but others we have to send out. Just looking at the grinder I was guessing 1940's to 1950's vintage.

Modern Direct Drive Toolpost Grinder
The spindles taking a common colket is a plus, the Dotco spindles and grinders often use the common Erickson 300 DA collet. When grinding on a lathe, keep in mind the lathes controls are coarse for grinding, so its easy to crash a wheel into the work with a small movement. So, with gaurds or not, stay out of the line of the blast.
