Apparently standard grade collets are grade A , AA collets are
concentric to 5 um.

Does anyone know the difference between the non AA and AA collets?

I assume that you meant "ER40". I use one of these on my Myford lathe (not
CNC!):

There are many other vendors charging more and less. Searching eBay for "lathe
collet chuck" will get dozens of hits such as

I'm thinking of ordering one of these for my 4th axis so that I can finally get
LCNC to do more than just demonstrate that I can rotate
it under computer control. It appears to fit the same registration as the
smaller 3 jaw chucks so a face plate that can register it or the
chucks would be in order.
Good idea? Or don't go that way�
It does look quite useful, link? And is it made in ER42?
Thanks John.
