WOW today was my first CNC cut with I think was a 7 series aluminum and wow should I have listened to you guys with using a coolant system. (chair)

The WD40 isn't bad, but I should be using some sort of coolant system! I noticed when not using any liquid (WD40), some vibration and very jagged cuts on the sides of my work piece.

I'm running my X1 CNC mill with -
1/8th 2 flute carbide endmill
cutfeedrate of 5
plungerate of 2
at 1800rpms

When using the WD40, the cuts were much cleaner, but it just looks like it's still missing something for the finish.

I thinking about making my own system. I was going to use a water pump from homedepot, but didn't know which one to go with or if the pumps they sold would be strong enough.



I found this site with directions on making a flood coolant system, buy I have very little knowledge with this. So if anyone would like to share any info or experiences with a system like this, Please feel free to share.
