End Mill Lubrication

[dragos28]

What are you guys using when milling aluminum?

So far I'm using WD40



I've also tried spray silicone

What's the best lubrication to use?

Years ago, I used spray silicone to lubricate a tap cutting aluminum. It seized immediately and the tap broke.

Many of us use WD40 to lubricate aluminum. Some use kerosene. I have used Crisco to good effect. I applied it with an acid brush. It ends to stay in place, so you can brush it onto the cutter or brush the work piece along the cutting path. It could make you a bit hungry though. Smells like baking.

I've not had good luck with silicone. WD-40 works very well, but I was having problems with it plugging up my no-fog coolant system. Kerosene also works very well and does not plug up my coolant system.

Like you, I use the WD-40 spray can for quick jobs.

Just a note: Wearing gloves can be very dangerous around anything that turns. They work great for working with hot or sharp stuff when the machines are turned off

The silicone worries me as it says its highly flammable and shouldnt be sprayed on hot surfaces.

about the gloves, you're right but i also make it a priority to be careful while working, so i dont reach for the piece until the mill is off.

Actually the silicone isn't flammable, but the propane or butane propellant sure is.

WD 40 in spray cans here in CA looks like milk now , I got some in a gallon jug that is regular, at least it was

Try some A-9 if you need a fine finish. That stuff is the best for aluminum that I've found.

Kerosene. Like WD40 but doesn't leave a slick residue on everything and is cheaper. Also is a great cleaner.

Mikey, what's A9? Please don't tell me I need another oil can!

Breathing small WD40 drops left in the air isn't good to your lungs. (They can't go out anymore) Use spray cans moderately. Or a breather.
