Acme Feed Nut For Diamond Milling Machine

[buffdan]

I needed a new feed nut for the x-axis in my Diamond 22-M horizontal mill, as the backlash was about .020.
I picked up some 932 bronze, and single point threaded a new nut.
The new nut works great and has ~.005 backlash.
The lead screw could be replaced.. Maybe another project.

Excellent! Did you purchase the tool point or ground it?

 

[buffdan]

Thanks, I ground it from HSS blank.

Very nice job.
Did you cut the first flat on the lathe also?

Thanks Tom.

I first cut the flat on the milling machine and used that flat as the reference surface for marking out.
It also made it easier to set it up in the 4-jaw.

Well traveled 22-M Diamond! Most were used in the SoCal aircraft industry or in film (Disney was reported to have about thirty of them lined up!)

I have a Diamond B12. It's completely worn out, taken apart and sitting in the corner of the shop awaiting the day that I rebuild it. I'm glad I didn't give much money for it.
