Save my sanity - 1050 grade aluminium

[Isaac]

Just dug out some 5083 that I normally cut at 0.4mm doc 800mm/m 15krpm. I took Jazzcnc advice about pushing it to see what your machine can handle and with a 6mm carbide(2 flute, 22k rpm and 800mm/m I have reached 1.5mm doc and it looks clean. I could probably push it a little more but I was getting sprayed with hot aluminium chips. It actually sounded better with the deeper doc.

Too bad the 1050 isn't 5083 :(

Then your cutting something like correct because you want the heat to leave with the chips and not stay in the material or cutter. That said 22K and only 800mm/min is a little fast and slow. You could try lowering the Spindle speed a little to around 15K or up the feed rate.

1050 is a pain in the Arse and I don't cut enough so still haven't found the balance but I've had most success with twin flute slot cutters and cut full depth in 2.5mm sheet.
