Are there any pin vises suitable for CNC drilling at high speeds for micro drills. A high quality high precision pin vise.
I know. I know. Sounds like an oxy moron. I think if I can find a pin vise that will actually hold the bits straight, and has low enough runout, it will be possible with correct speed and feed calculations.
I bought two mid price pin vises from two different sounces, and unfortunately neither holds a drill bit particularly straight.
In the mean time I ordered some carbide micro drills in the sizes I need, but because of their DOC capabilities, I'll need to back drill the part. Oh, joy. A secondary setup for a part what fun. LOL.
FYI: Did some tests with what I had and found HSM Adviser wanted to feed way to fast. As a check I plugged the same numbers into ME Consultant, and it indicated less than half the feed rate of HSM. The HSM numbers flexed and broken drill bits very quickly. Haven't retried yet with the ME numbers.
