We have a turning job that will require installing a 4.5" bore in solid material, among other ID and OD features. Due to timing, there is no time to entertain having the blanks water-jetted to a nominal bore size for cleanup in the turning center. Plus, the price won't allow it.
So, with that said we're looking for recommendations on a boring bar and insert combo that might help us remove material faster than we might normally. Machine is 15HP spindle with gear drive transmission, so I think the power is there. And, it's as stout as any other machine in its size range that I have ever run. So, I'm not worried about that. However, since the vast majority of what we do is typically MUCH smaller and not usually removing this much material, I'm not really sure what I can expect to achieve. Right now, I am thinking to hold it in Pie jaws since I am only going to get .500" to hold onto. ( which obviously will also have effect on how large a cut we can take ) Part gets flipped for 2nd op install of feature on other face.
Material is 4140 Pre Hard. 6" diameter, solid. 2.125" thick. Any recommendations on a tool/insert combo?
Thanks.
