Hi,
I finally got around to CNC'ing my HF Micro Mill #47158!
Just curious what depth and ipm others are using for aluminum on these micro mills(or mills where RPM max is limited to about 2000rpm)?
So far...I've got a couple of passes on aluminum that have burr all over the path and made 3 sets of broken HSS 1/16" 2 flute micro end mills. Not looking forward to making any more of either these. ;-)
The flat bar of aluminum was from Home Depot but am not familiar with the different types of metal to tell what I got. It's the flat aluminum that comes in 1/8" x 1" x 3FT.
I need to keep records of my trials but I believe i was running:
- between .5 and 1 ipm @ 2000RPM, depth around 0.010"
- and another time with 5-6 ipm @ 2000RPM, depth around .005"
Hate to go any slower since my controllers get HOT the crawling 1ipm speed.
Thanks in advanced for your comments,
Dang
To add, I was able to make a clean letter engraving on another unknown piece of aluminum(different), but again I had to go around .5-.7 IPM.
This piece of aluminum felt like chrome/plastic more than metallic aluminum, but the freshly milled faces clearly shows that it's metallic.
