Dry Aluminium Cutting Problem

[Jonathan]

You might think it is just "air and the odd squirt", but experience tells you when to blow and when to squirt

I find a syringe works well for this as you get better aim. Before I got the aluminium bed I would have to slow down for thin parts, or lots of parts at a time. I don't always use flood coolant with aluminium, as it does make such a mess and isn't worth it for a lot of things.
