...HLVH threading method is just awesome. You can thread RIGHT up to a shoulder, no stress, the machine stops on a dime, automatically, right where you tell it to...
The HLVH is truly amazing for its wonderful design which provides this capability.
The pin clutch stops to about +-.001. And you can thread at 800 rpm.
Use carbide and get a great finish.
I do not understand the “HSS better finish” if so aerospace would be using it.
