Guys,
Last weekend I ran out of cooling fluid and wanted to get a small job finished on the lathe. I recalled watching one of Adam Booth's Youtube clips that shows his mist cooling arrangement on his mill. They say that necessity is the mother of all inventions, so whilst I didn't have mist cooling abilities I did have some air available and wondered how I could utilise that.
My rather heath robinson attempt to provide additional cooling to the tipped tool was to hold the blow gun a small distance (75 - 100mm or so) away from the tip. Granted I wasn't taking heavy cuts (on my Hercus 260) but heavy enough into 2" DIA 316 Stainless to think I should cool things down a bit.
Im fairly sure this method worked although of course I can't quantify it and I know its no where near as efficient as liquid. I also know that in the absence of a flood cooling system, applying a constant air flow to the tip by attaching it to the saddle is easier, more consistent and smells less that applying oil / fluid with a brush.
I know there is the whole debate about cooling tipped tools (or not) and thermal shocking the tips with sudden cooling.
My question really is to do with benefit - do you think there is any benefit of pursuing this to a more permanent solution? Im thinking of a small brass ball valve with a nozzle on one end and an airline at the other. I already have a suitable mounting point on the saddle, left by the previous owner.
Thoughts please.
