Re: [CAD_CAM_EDM_DRO] Re: Sizing servo motors for BP size mill

Hi, one of my friends just got back from a small "CNC" show to demonstrate
their high speed 3800 fpm. The vise went 10 ft. off the end of the table as
the spindle nose hit. apparently a misread by the computer or perhaps a bug
in the softwear. They all laughed and mumbled. I'll bet they all hit the
vise or jig once in their lives. I know I did "ONCE" on a Cincinatti #5 mill
with disasterous results....cul brian f.
