e. Spheroidizing annealing (better than normalizing), detecting hardness and metallography

f. rough machining

g. Drilling and boring inner holes

h. fine finishing

i. Milling inner flange hole

j. hobbing splines, detection

k. Drill oil leak holes and remove burrs

l. Carburizing and quenching require special attention to thread protection; testing hardness and metallography

m. Grinding splines, testing

n. Surface magnetic particle inspection

o. All inspected and laser marked, oiled, and protectively packed
