Making sure this automation part is manufacturable

What does deadspace mean?
A centre hole in each end so it could be held between centres.

And with the flange end center recessed the flange but end could be ground at the same time as the other ground aspects..or hard turned.
Do a little reasearch to find out how hard most shuch parts are made.
Possible the flange could be welded on the shaft and then all the turning /grinding done. . A big outfit mighe friction weld it.

I'm thinking 1045, hardened similar to motor shafts, which is hard but not that hard. I'm seeing a very wide range of hardnesses from water quenching 1045. Maybe 45-50 HRC?

I did turn some prehard 1060 (Rockwell C60) on my unmentionable brand lathe but I do not intend to repeat that.

You can turn that with carbide on a decent lathe.
