My first CNC is a POS and it will cut alum. Turn the rmp down slow so you do not get your bit hot, and use oil. I just use Pam Cooking Spray, but everybody thinks I am cooking Chicken. Cut at about .05 to .08 ipm and at .1 inch deep per pass. Use a new .25inch upcut bit It does OK but slow as s..t. As long as your not making NASA rockets it will work
If you try any faster speeds let us know
Use what you have, Not what you wish you had.......
