Also agree that a drill press isn't ideal to use as a mill, but sometimes you just need to use what you have. 
I have an old 17" Delta drill press with a custom-made arbor that has a 5/8"-16 threaded mount so the chuck will not fall off.
I used it to do a project that would have normally required a mill with a rotary table.
Needed to repair a broken section of the flange on a cast-iron band saw wheel!
Basically, I set-up the band saw wheel centered on a piece of plywood attached to the base of the drill press & used the wheel as the rotary table.
I first used an angle grinder to get most of the material removed, so there was less than 1/8" to clean-up with the end mill.
Being it was cast-iron it was easy to machine so I used a fine pitched 4-flute roughing end mill & slowly rotated the wheel into the end mill.
I used self-tapping screws to hold the repair piece in-place & then I drilled & counter sunk some flat head screws from the other side of the wheel that were tapped into the repair piece. I used JB-Weld while assembling it & after that set I ground off the heads of the self-tapping screws & used some more JB-Weld finish up any gaps.
Finished wheel.
