Hi,
I need some steel bushings that should have 11mm lenght, 6mm OD, 1mm ID, OD and ID centers can missmatch not more than 0.03mm.
Which way I will get most close results?
Using lathe and turning from rod in one setup looks most easy way, but:
- tailstock center height is never aligned with spindle center
- even if drill will find center on the face surface, just wonder how far from center it will exit at the back surface.
I can also use manual mill to make hole (after OD is done with lathe). Indicating center with OD will be easy, can use smaller drill first and proper size mill to finish hole. But:
- 1mm mills is probably more rigid than 1mm drill, but anyway it will have reasonable deflection with 11mm length.
So, if making small hole concentric to the OD is so hard, maybe I need to reverse operations?
Drill smaller hole, finish it with reamer, and then use tool grinder with 1mm arbor to finish OD? Does this looks realistic?
Thanks.
