Mini-Mill / Router - Cutting Fluid??

[Boyan Silyavski]

Recently i started using pure virgin cold pressed high quality Olive oil for everything and greatly recommend it.

All started as a friend of mine bought 5l from the cold pressed olive oil in a market, but did not like that particular taste. And as we always have 5l bottle at home, so i did not need it,so instead of throwing it away i took some for the MIG welder as i was dipping the tip in machine oil and had to use respirator for the fumes. It worked perfectly. No respirator needed now. I use it also on metal instead of ceramic weld splatter protector. Just brush table and parts in oil . Then i needed to thread 800 holes, so i gave it a try and it worked better than the threading oil.

Come on. I was genuinely surprised. It works for drilling and machining too. Also for preserving metal parts. Though i still apply it manually. Just the other day we were discussing how to mix it with water and use it in the mist system.

So if anybody has some ideas how to achieve homogeneous mixture and how much water and what about rust? I simply dont have the time these days to experiment on that. Though near seaside steel treated with said oil holds against rust very well. And i surely have rust problems living 300m from sea.

One thing that i guarantee you, is that it will be good for your hands, and it works perfectly on level with fine special purpose threading and cutting oils.Its not related but people quench in it and it works as well as a good quenching oil.

Note should be taken that i use the real deal-100% cold pressed oil, as i live in Spain. Not to speak of that the price is just a bit more per L than kerosene. Now i ask my self, why my hands were ever in a machine oil all day
