As promised I did indeed cut aluminum on my new machine last night. This is my C3D logo out of 3/16" (4.8mm) 6061 aluminum using a 1/8" carbide end mill. 0.2mm passes, 100mm/min feedrate.
Looks sweet
What machine did you use to cut the aluminum? If I may ask I am new here.
3040 CNC frame with ball screws and spindle only, I separately purchased and put in the stepper motors and a good control board.
You can find the 3040 CNC’s on eBay. Not sure if they’re still doing mechanics only with USA shipping.
Thank you.
Looks rather nice … always use a good coolant…
And you may not believe it, but aircraft grade 7075Aluminium is easier to cut then the cheapish alloy from DIY store (Al99) this is much more plastic and fills the flutes rather quick if not properly cooled as it is getting like dough when warmed . You perhaps you could sharpen your edges and decrease the effort of deburring by using some harder alloy if your router is capable to
