1mm dia thru coolant drilling x 1"
Need advice and reccomendations on drilling thru 1in CS. I am able to do this on a Milltronics VMC at 4,000 rpm, 1,000 lbs pressure introduced into toolholder.
Mitsubishi drill has (2) .005dia thru holes. Limited to 4K RPM by coolant inducer.
Mits says it needs 10K- 16K Which makes of machines should I look at?
Without knowing the outside dimensions of the part see if someone in your area has a edm "hole popper" we use ours for .5mm holes .800 deep. Can't imagine doing very many small hole any other way.
