Evening, at the moment I'm machining some very high profile 316 parts. The parts are made from large billets and a lot of material is removed so something that can eat through it would be ideal.
So far I've tried the WNT 63mm feeed mill (the tips for this used to be brilliant - 3750mm/min at 1000rpm for ages!) but the latest tips are quite poor and don't last anywhere near as long!
I've also tried a "Sumitomo WEX250F" but discovered it's nowhere near as good as the price tag or the sales rep suggests.
I've tried a vast range of speeds and feeds (as suggested by the manufacturers) with and without coolant/airblast but to no avail.
Can anyone recommend any tooling that's up to the job? It needs to be available in the UK too!
check with a mitsubishi rep. they have carbide graqes that really do well on thi material
