Newbie looking at 6040 (China CNC) for polypropylene 15mm sheet

WD40 is good, a squirt every now and then or buy a mist system on ebay (£10 ish) and you'll be good to go...

I actually found some draper cutting oil the other day that works better than wd40 imo (doesn't smell as bad when it evaporates off a hot tool either!) https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1

It's a good temporary solution to no coolant I reckon!

Mist system is the better long term solution though, you already have the compressor so it's not difficult to set one up from there.
