I'm running a brand new VF-1. 10k RPM with gearbox.
It's total runtime is probably under 20-30 hours. No more than 40 tops.
I've been running it almost continually for the last 5 hours. Cutting 6061 aluminum. Mainly 1/2" ball and flat endmills, moderate DOC at 7500-10K rpm, from 60-90 IPM.
Stopping between parts, it felt noticeably hotter inside the machine enclosure than out. I felt the spindle, and it feels like it's around 85-90*F. Definitely hot to the touch.
I can't imagine this is normal, however I figured maybe running it at 10k for the last 5 hours might have something to do with it?
anyone have any input?
Thanks,
Cory
