Smithy GN1300 - Manual (Page 64)

Overview
Before using the more advance features of your Granite 1300 Series Lathe-Mill-
Drill, it is important to have a basic understanding of feeds and speeds. This
section contains information on how to set the speed and feeds rates for your
machine. We encourage you to learn and understand as much as you can about
this fundamental element of machining. A general reference guide such as the
Home Machinist Handbook or the Ready Reference are good reference guides to
assist you with this task. As always, remember to follow the general safely rules
listed below and in Chapter 2 of this manual.
Speed and Feed Rates Defined
Speed is how fast the spindle rotates. Feed rate is how fast the cutter moves
along the workpiece.
Speed and feed rates are calculated based on the type of material you are
cutting, the size of the material and the type of cutter being used. Refer to the
Home Machinist Handbook (Item # 10-005) or Ready Reference (Item #10-015)
for more detail. Remember, speed and feed rates are given in a range and you
will need to adjust within that range for your machine’s size and power.
8 Speeds and Feeds
For your own safety and the safety of those around you,
follow the rules below.
Never leave or walk away from an operating machine.
Do not change motor rotation direction until the motor and
spindle are fully stopped. Changing directions while the motor
is running can damage the motor.
