Threading - Grizzly G0776 Owner's Manual

Threading

The following subsections will describe how to
use the threading controls and charts to set up the
lathe for a threading operation. If you are unfamil-
iar with the process of cutting threads on a lathe,
we strongly recommend that you read books,
review industry trade magazines, or get formal
training before attempting any threading projects.
Headstock Threading Controls
The threading charts on the headstock face dis-
play the settings for inch and metric threading.
Using the controls on the lathe, follow the exam-
ple below to understand how to set up the lathe
for the desired threading operation.

—"A2" indicates that the dial marked A–E
must be set to the "A" position, and the dial
marked 1–5 must be set to the "2" position.
—The sub-row "I" indicates the dial marked
I–II must be set to the "I" position.
—Because the thread pitch is in inches (stan-
dard) the dial marked S/M must be set to
the "S" position.
The lathe is now setup to cut 32 TPI threads.
