I really think your lathe is too small to be effective making that many parts in that size, even converted to CNC. Consider how you are going to hang on to the part to do the work on the OD and ID, that is going to require at least 2 setups, and some special chuck jaws for reasonable handling. Then there is cutting each piece to length before turning.
I guess I would farm those parts out to someone who has a CNC lathe with at least a 2 inch spindle bore and bar feeder and thus can run bar lengths. Looks like they would take about 40 seconds each to make.
Not sure what the end use is, but that looks like a stock flanged bushing, so maybe look at the overall design and see if a stock bushing would fit your application. Where possible, I normally design to use off-the-shelf parts.
