Re: ER-32 Collet Nut Threads #MISC

 

Have you checked the?pitch with?a thread gauge ?
Have you swapped out and checked?fitted against your other ER 32 nuts.
I think a?typo?error, or most strange.
If it is 1.0 mm pitch, then IMHO I see no issues.
I doubt if you ever will ever need to replace this?nut.
Most important is the 16 degree?incl internal taper angle
and does the nut clip onto the noses of the ER 32 collets.

Cheers
?John

Hello, All,

I have several ER-32 collet chucks of different types; one for my mini-lathe, one for an R8 spindle to match my mini-mill, and a 2MT for my rotary table. These all use the same M40-1.5 collet nut, which is basically available everywhere.

I recently purchased and received an ER-32 Spin Indexer from Little Machine Shop, for use on my mill. To my surprise, I noticed that the collet nut threads are M40-1.0, not M40-1.5. I spent a little time searching the internet and could not find an ER-32 M40-1.0 collet nut. My concern is where I will obtain replacement nuts if and when this becomes necessary. I will email LMS and ask if they carry these collet nuts, but am concerned that I may be out of luck in the future.

Does anyone know if M40-1.0 is used routinely on ER-32 collet chucks?

Thanks to everyone for their help!
