Hello 5 axis,
I have a have a small(machine) job shop in Menomonee Falls, I was wondering if I could pick your brain about hard milling A-2 56/58 RC. I have just burned through 4 -$122.00 OSG end mills. Milling a side pocket .690 x 2.375 x 1.3 deep.
The rep from OSG said .750 depth of cut w/ .03 step over @ 40.00IPM
Lasted until it hit the steel
Thanks in advance,
Jim
