Dean,
I don't know if anything will eliminate this problem on a lathe. I prefer to rough mill (with helical ramp entry) stringy materials when possible, in order to force the production of broken chips.
On most lathes, you can use a G83 pecking cycle as a chip breaker for face boring such as you are doing. It might be an extremely short peck though, because lathe turnings are very long, very fast
