I have a part, 1018 cd steel, held in a raptor dovetail clamp on a rotary axis. There is one particular dimension that I need to reach and finish mill 1.350 deep while only taking off .005-.010 from the side to be finished. I can't have any tool deflection, or at least minimal.
I was using a 3/4" carbide end mill in my old Fadal when doing this, but the BT30 spindle doesn't really like a 3/4 tool.
So my question is, to take a finishing pass 1.35deep on 1018 what diameter tool will work best in the BT30 brother spindle? 1/2" dia? 12mm? 3/8"? Also, 3 flute, 4 flute, 5 flute or more? I don't want a lot of tool pressure so I am thinking 4 flute.
But for those that have used the brother on steel, what kind of parameters are you doing to keep a nice square cut?
Thanks for all input.
