My first attempt at cutting aluminium highlighted the need for a lubricant. Though i might have gotten away with it if my cutter had been new and I'd kept the cut depth shallower. My criteria are: low mess, low smell, non-toxic, no special equipment needed, and environmentally friendly. But it has to work well too of course! So this thread is for recommendations and discussion of lubricants for light aluminium cutting on a small CNC router machine like an ox or workbee. I've seen all sorts of recommendations: dedicated lubricants (often with unknown ingredients) , WD40, kerosene, motor oil, beeswax. I really like the idea of using beeswax as long as it actually works well enough. I have plenty on hand, and it would meet all my other criteria.
