I have a older BridgePort J Head with R8 collets I bought several years ago and I normally use it to mill 6061 Aluminum with no issues. I also inherited a bunch of shell/face mills Of all different sizes ranging from 2" up to 8".
I have been working on a part that is 1018 Steel and have been cutting or shaping it with a 3/4" 4 flute HSS coated End mill.
RPM = 1110
Feed Rate = Max power Table feed
DOC = 5mm
WOC = 5mm per pass
With Cool Mist spray
Chips are coming off with a Bronze color to them.
The Max material I need to Remove is 1" DOC x 1" WOC with a Total length of the part being 5". I'm not encountering any problems currently but I'm wondering if it would be more beneficial to use one of the shell mills instead. I'm thinking maybe the Shell mill will allow a deeper or wider cut or maybe it would just be better for wear instead of the End mill. It seems I could take a deeper cut with the End Mill but not Climb milling as the table will jump with backlash. I cant go any faster on the feed rate as it is maxed out (unless I turn it by hand).
Anyway I would like to find a use for the Shell mills and not cause unnecessary wear on my end mills if possible. Any ideas?
