Correct, "swing" in machine tool talk is radius (like a swing hanging from a
tree). "Swing over carriage" is another important measurement, on some
lathes the carriage gobbles up a lot of swing.

Is this the Maximum diameter a Lathe can turn?

So if I measure 3" from the spindle center to the bed rail then the
"swing over bed" would be 6"?


Thanks in advance
