Mitsubishi titanium mill
One of our new indexable milling tools. 2.5 diameter cutting 2.25 deep, .25 radial per pass. Speed was 1220 rpm and feed was 21.4. The part was 4140, 14.75 long, held in a 6" vise. Sparks were due to needing three inserts replaced from the last job, but will cause no problem.
