22Js on the EE

[sneebot]

Wanted to do this for quite awhile. I have two other machines that use 22J collets and the ability to use the on the EE seemed like it would come in handy.

2nd image shows the comparison to a 5C chuck.

Another comparison. I recently picked up about 45-50 22j collets with some duplicates. If you have duplicates and want to do some trading let me know.

Nice! What's the part number of the 22J chuck? Does it have an integral D1-3 back?

The chuck had an L2 taper adapter when I bought it (4 bolts and that came off)- I machined a D1-3 back plate to fit.

That looks very nice. I have a Cushman 215 collet chuck for that size range, but it doesn't quite reach 2" as the 22J does.

22Js have a capacity of 2.25" (That's a 1" TPG shaft in the collet).
Advantage of the Cushman chuck is that it's a bit smaller. 215 collets are also generally cheaper. However, I've never seen a 215 emergency collet- I've aquired a number of NOS 22J emergency collets which will hopefully come in handy at some point.

They used to make 215 emergency collets but it looks like new ones are a request at Hardinge or a crapshoot from India. I don't have any, I make do with Hardinge step collets and other 5C solutions. I do have a Cushman 115 emergency collet, go figure.
