Hi Guys,
I would really appreciate some help on machining Aluminium on my Pacer CNC machine.
I am going to cut a casting mold out of a 250 x 250 x 32mm slab. ( i purchased 3 grades to test the quality - 5083, 6032 and ecocast)
I have a 6mm 30mm cut twin flute and a 4mm 40mm cut twin flute aluminium tools to do the job.
My machine has a 2KW air driven spindle (pacer compact cnc) on an auto tool change system, and a misting spray system installed.
What feedrates would i need to use, and what pass depths could i get away with?? do i need a high spindle speed, the max i can go is 240K. I need to achieve a high quality finish, all my design work is carried out in aspire.
Again i really do appreciate all your help.
Cheers
Steff
