21. TWO–PATH CONTROL
FUNCTION
369
Two–path control can be used with a lathe that supports simultaneous
cutting by its two independently operating tool posts.
Series 16–TB (two–path control) can be used for a lathe that machines one
workpiece attached to one spindle with two tool posts simultaneously.
For example, while one tool post is performing outer surface machining,
the other tool post can perform inner surface machining, thus reducing
machining time dramatically.

Series 16–TB (two–path control) can be used for a lathe that machines a
workpiece attached to each of two spindles with two tool posts
simultaneously. In this case, each tool post operates independently of
each other as if two lathes were used, thus improving productivity.
