Cutting Aluminum

 

Years ago, maybe here or one of the other groups, someone recommended using WD-40 as a coolant/lube when cutting Aluminum.
I have done so ever since because I have found that I seem to have fewer problems than when using it rather than other stuff.

Just my $0.02 Your mileage might be different!

Kerosene works great for cutting aluminum, and it is cheaper than WD40, even when you buy it in bulk.

I too use WD 40 for aluminium, works well, so well in fact I bought a gallon of it and a spray bottle.

I too have always used WD40 and recently I came across another make GT85 with PTFE and this works well too.

I would think kerosene would give off a nasty smell I don't know I have not tried it.

A few years ago I had to make and cut some very fine 2 1/2D in relief medals on the cnc I made a dam wall of putty around them and flooded it with Johnson's Baby Oil they turned out fantastic finish.

I had an experienced machinist tell me WD is better than common cutting oil for aluminum.
 

This is correct, very thin oil like WD40 and kerosene are, by far, preferable for Aluminium.
