X-Axis Power Feed
The mill is equipped with a power feed unit for
X-axis table movement. Refer to the illustration
in Figure 22 and the descriptions below

A. Limit Switch: Stops table movement when
either of the switch side plungers are pressed
by the limit stops.
B. Limit Stop: Restricts table movement when
positioned along the front of the table.
C. Rapid Traverse Button: Moves the table at
full speed when it is in motion.
D. Directional Lever: Selects the direction of
table movement. The middle position is
neutral.
E. Speed Dial: Controls the speed of the power
feed. Turning the dial clockwise causes the
table to move faster.
F. Circuit Breaker Reset Button: Resets
the internal circuit breaker if the unit is
overloaded and shuts down.
G. Power Switch: Turns the power feed ON and
OFF.
H. X-Axis Ball Handle: Manually moves the
table.
I. Graduated Index Ring: Display the distance
of table travel in 0.001" increments, with one
full revolution equal to 0.200" of table travel.
To confirm the power feed settings that you will
be using during operation, we recommend that
you use the power feed to move the table through
the intended cutting path before starting the
spindle rotation and taking the cut.

To operate the X-axis power feed:
1. Loosen the X-axis table locks (refer to
Figure 20 on Page 27 for locations).
2. Position the limit stops along the front table
slot to limit the distance of table travel that
is correct for your operation.
Note: Make sure the cap screws firmly lock the
limit stops in place when positioned.
3. Turn the speed dial all the way
counterclockwise to the slowest setting, move
the directional lever to neutral (middle)
position, then flip the power switch up to
turn the unit ON.
4. With your hand poised over the power switch
in case you need to suddenly turn the unit
OFF, move the directional lever in the
desired direction of table travel.
5. Use the speed dial to slowly bring the speed
of movement up to the desired rate.
6. When you are finished using the power
feed, turn the unit OFF, then rotate the
speed dial all the way clockwise and move
the directional lever to the neutral (middle)
position to avoid unexpected table movement
when you next flip the power switch up.
