Yes. And, no.
"Automatic" means that the firearm fires more than one shot with each function of the trigger. Turning a crank, no matter how fast the gun fires, still requires the trigger to be operated for every shot fired. The crank is not a trigger.
Gatling guns are not machine guns, and are perfectly legal without NFA registration. Gatling guns that run off of electric motors
are machine guns, because the "trigger" is an electric switch, which will fire the gun multiple times so long as the trigger is depressed. But if you're turning a manual crank, it's still firing one shot per function of the trigger.
Great volumes have been written on this subject in the Class III community, and it's all well documented by BATF.
