Hello,

Sorry to bother you all with such a dumb newbie question here.

I recently purchased a medium size CNC mill which has a 1.5hp 6000rpm spindle.

My problem is that I have a job that I have to complete sooner than I have time to learn how to use the machine.

The part is flat stock .100" aluminum that I need to edge mill off 1/4" of material.

I currently only have collets for 1/4", 3/8", and 1/2" along with some end mills from Harbor Freight,2 flute and 4 flute set.

I cannot use coolant as the parts I have to mill have components on them. So I'm guessing I'll use up a bit or two in the process. I could possible brush something on the bit as it's going but I need to keep it to a minimum.

I could use a little help figuring out what speed I should set my spindle to as well as the feed rate that I should use.Also any tips would be greatly appreciated.


Thanks in advance.

Greg
