I'm taking 3mm off all faces of some flame cut 304 stainless steel plate - tough, 300mm sq, 50mm thick - but am struggling to get above 80m/min (260 ft) on my cutting speed. I'm using these tips at the moment - https://www.cromwell.co.uk/shop/cutt.../p/MTS1226266X - on an 80mm face mill, 2mm cut.


Anyone suggestions? Different tips? Different strategy completely?


I'm using CAM so could generate some small cut hsm style paths if that might help.


Cheers
