I know this would be a super easy job for most of you, but I want to make sure i do it right.
material is 7075 aluminum anodized. Its the side of an AR-15 billet lower reciever. I am machining some improper engraving (not atf related) off the side.
it will need to be 2.5 inches long, and around .20 deep.
A 5/8 end mill will cover the width i need it to cover.
What speed feed would you use, what lube?
is a HSS 5/8th endmill going to be an appropriate tool?
I plan on taping the rest off when finished and blasting the machined area and trying some aluma black to recolor it. If that doesnt take then the whole reciever is going to be recoated.
I have been struggling w/ the whole machining aspect of gunsmithing so i want to make sure i get this one right, it will be a huge confidance booster.
