SECTION 4: OPERATIONS

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 and seek additional training from expe- rienced 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 the risk of eye injury from flying chips always wear safety glasses.

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 or hair that could get entangled in moving parts.

2.Examines workpiece to make sure it is suit- able for turning, then securely mounts it in lathe.

3.Installs tooling, aligns it with workpiece, then backs it away to establish a safe startup clearance.

4.Removes all setup tools from lathe.

5.Checks for safe clearances by rotating workpiece by hand at least one full revolution.

6.Moves slides to where they will be used dur- ing operation.

7.If using power feed, selects appropriate feed rate and direction.

8.Resets Emergency Stop button and turns spindle direction switch to "F".

9.Rotates variable speed dial to set correct spindle speed.

10.Uses carriage handwheels or power feed options to move the tooling into workpiece for operations.

11.When finished turning, rotates variable speed dial to "0" to stop spindle, presses Emergency Stop button, then removes workpiece.
