I just finished up my CNC quill drive conversion my Bridgeport and would
like to use it to drill boards. I have not found a reference to what
speeds and feeds to use for drilling.
I am looking for the surface feet per minute and feed per turn numbers
for small carbide drills in FR-4. My 5400 RPM maximum going to be
well below the 30,000 to 60,000 RPM used by a real PCB drilling spindle
but it should still work fine if I use the correct feed rate.
Anyone got a reference for these parameters.
