3) Would it be wise to epoxy granite the base & column right when I get it?
4) Should I be able to run a 3" Glacern Facemill on this mill with epoxy grante & with a 3HP VFD and not have an issue as long as I don't take too big of a cut?
Thanks in advance...
1. Ask Tommy about the breaker or wait and check the VFD documentation.
2. Mine came assembled in the crate. I had to disassemble it partially to get it in place. The one I CNC'd I bought already completely disassembled.
3. I like my epoxy granite, and the results are noticeable versus my second mill which is stock. With that said, it is not a profound difference. Things are just more solid. If I had to guess, I'd say 15-20% rigidity/vibration damping improvement. It's not hard to do an E/G fill. I spent a day prepping the base, a day filling the base, and a day filling the column.
4. I sure hope so because I just bought a 45 degree face mill from Glacern!
I don't think there will be a problem with the facemill, depending on how deep you want to cut. I don't have the Glacern to try yet, but I have an Iscar 2" with APKT inserts (90 degree shoulder) and a Lovejoy 3". Both are great performers and I regularly cut 150 thousandths. They might do more, but that seems to work out pretty nice for a roughing cut. I drop back to 30 or 40 thou to finish.
With my 3" face mill, I run 900 rpm and 32 IPM on aluminum. Those are the recommendations from my G-Wizard feeds and speeds calculator and they work very nicely.
