SECTION 4: OPERATIONS
Keep hair, clothing, and
jewelry away from mov-
ing parts at all times.
Entanglement can result
in death, amputation, or
severe crushing injuries!
Complete the Test Run & Break-In proce-
dure on Pages 18– 20 before using this lathe
for any cutting or threading operations; oth-
erwise, gear box damage will occur.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any proj-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable
for accidents caused by lack of training.
To complete a typical operation, the operator
does the following:
1. Puts on safety glasses, rolls up sleeves,
removes jewelry, and secures any clothing,
jewelry, or hair that could get entangled in
moving parts.
2. Examines workpiece to make sure it is
suitable for turning, then securely mounts
workpiece in chuck, between centers, or on
faceplate.
3. Mounts tooling, aligns it with workpiece, then
backs it away to establish safe startup clear-
ance.
4. Clears all setup tools from lathe.
5. Checks for safe clearances by rotating
workpiece by hand at least one full revolution.
6. Sets correct spindle speed for the operation.
7. If using power feed, selects the proper feed
rate for the operation.
8. Starts spindle rotation, then engages half nut.
9. Uses various carriage controls to move the
tooling into the workpiece for operations.
10. When finished cutting, disengages the half
nut (power feed only), moves the spindle
direction switch to the OFF position, waits for
the spindle to completely stop, then removes
the workpiece.
Operation Overview
The purpose of this overview is to provide the nov-
ice machine operator with a basic understanding
of how the machine is used during operation, so
the machine controls/components discussed later
in this manual are easier to understand.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual, seek additional training from experienced
machine operators, and do additional research
outside of this manual by reading "how-to" books,
trade magazines, or websites.
To reduce your risk of
serious injury, read this
entire manual BEFORE
using machine.
To reduce risk of eye injury
from flying chips always
wear safety glasses or face
shield when operating.
