Milling 3mm aluminum with my Shapeoko2.
2mm endmill, 2 flutes, feedrate 600mm/min.
Awesome
Nice way to do the bends - since you do 3mm alu you need to reduce material in the bend.
I see there is a slight offset in one of the bends, so thats the risk you need to include in that kind of bends.
But hey, it looks good, im looking forward to be able to do that kind of work in my CNC shop.
Yep. If you don’t cut the groove, it’ll break.
Impressive. Very clean looking job, and cool to see how the part is used. What are the specs on your spindle?
Nice. What CAM program do you use?
@Heath_Aiken thanks. It’s a Kress 800 at 21.000 rpm.
@Michael_Jacobsen I’m using CAMBAM. I’m still learning, but it seems to go quite well. Only missing a mac version.
Yeah, know the feeling…
That is really nice. When I saw the parts made by inventables with the stock spindle it looked sloppy, wheras yours look nice - Is this just the spindle?
Those parts looks really great. Makes me believe more in milling aluminum on the shapeoko. I’m going to start doing more aluminum soon. Do you use oil at all? Or just let it go raw without lubricant?
@Adam_Conway Yep. Just a new spindle, rest is stock shapeoko. Had to use only 0.2mm DOC, otherwise broken bits and too much tool deflection.
@jlauer I use WD40 sometimes. Result is slightly better than. Problem is the chips are sticking together with WD40. So I don’t use it when I’m using my dust shoe.
Thanks, what do you do for depth of cut per pass?
@Adam_Conway 0.2mm DOC
Isopropyl will work well as coolant when machining aluminum. No sticky chips.
will try that …
if you do isopropyl make sure you have very, very good ventilation.
What kind of aluminum is it? Al Mg4.5 Mn0.7? Looks great!
Thanks 
It’s AlMG3.
