For the most part I post here when I have problem with my 440, but now that is up and running again, here is part I just finished that I am really happy with how it came out. The size of it is about 3.54" wide, 4" long and 1.25" thickness. Material is aluminum 6061. All machined on 440, couple of holes hand deburred otherwise untouched. Even the big threaded hole was spot on...

Looks great. How long did it take? I assume you used a thread mill?

One side took about 42 minutes other about 12. Manual tool changes, no power draw bar yet. For prototype parts this works. On side note I used .75" Shear Hog for roughing out everything. That worked out so great, I love Shear Hog! Reason I like it though is because it creates very manageable chips which are easy to clean and also because it throws chips very far which works excellent with FogBuster and they all get out of the pocket. No need to remove chips from part while its machining.

Nice looking part. What did you use to program it?

Thank you. All done in Fusion 360.

Nice work!

What did you use for the finish profile?

Did you use the carrier method in order to complete the entire profile in the first op?

[coffeetek]

I used Talon jaws and completed entire bottom side (first photo) and outside profile in first op. I used 1/2" Variable Flute Lakeshore Carbide for finishing. Reasoning was that I wanted stiffest tool to get best side wall finish and that worked out great. I have some parts machined by the pros on big VMCs and finish I got on Tormach is just as good. Very happy with what I was able to get out of this little machine.
