Ok I have a bit of a different one;
Anyone know of any practical resources for determining how and when additives are forced out of oils by a centrifuge or filtering?
We use a straight cutting oil in machines cutting metal, the oil drips of the metal scrap and gets put back in the machine.
The cutting oil is normally a mineral oil (group III) with an inactive sulfur EP and some DiEster added.
Currently the oil gets filtered to 5micron and reused.
Over time the machine slide lubricant oil, a heavily iso68 with a tackifier and its own aw/ep additives, bleeds into the cutting oil.
I wanted to try to use a WMO centrifuge to remove the metal fines and any disolved sludges in the centrifuge... Rather than having them redeposit in the machine.
I heard murmurings of centrifuges even at 1000G's will pull out additives?
Our oil rep says 2micron is the limit for depth filtering, otherwise the EP will be removed.
Thanks guys
