wants some flats and a slot cut through. I did a basic hand shaping of
the flats with a diamond file and cut the slot with a small diamond
blade I just happened to have. Looks to cut pretty easy with diamond,
but I'm wondering if anyone has machined this stuff with anything other
than diamond. Quantities would run from the low hundreds to several
thousand a year. They know what a pain this is and are willing to pay.
It's all but a done deal if I say I can do it.
Parts are .231 OD, .115 ID and .062 thick, the slot is .035 right
through the side. Small and fragile.... I'm looking at 4 setups to grind
these, but if I could mill them, might get away with just 2. I've
noticed the stuff is slightly magnetic and some grit from the grinding
sticks to the part. Assuming carbide or similar will cut this with some
semblance of tool life, I'll have to deal with these particles to keep
from recutting them, something that surely will shorten tool life....
Anyone with applicable experience?
