There is a custom adjusting screw that I buy commercially and when I get them
the threads have a text-book geometry to them. That is, they have a small flat
top on the major diameter and small flat bottom at the minor diameter or root.
They are made to class 2 or perhaps even class 3. I know that these screws I
am getting commercially are made using single point carbide insert tooling on a
cnc lathe.
By the way, this seems to happen for nearly every thread I have cut on the
machine, but I haven’t cared as much in the past as the screws have been for my
own purposes, but this one will be used in a product sent to customers.
SNIP
I am wondering if I am doing something wrong with the insert I am using or
what. Any thoughts?
Get an insert for that particular TPI, it will leave the proper flat on
the top and bottom of the thread.
