Locks; Graduated Dials; Vertical Head Movement; Tilting Vertical Head - Grizzly G0727 Owner's Manual

Locks

The table is equipped with X- and Y-axis lock
levers (see Figure 15) to prevent unexpected
movement along either axis when movement is
not required. This helps ensure close tolerances
and accurate milling results.

Graduated Dials

Each handwheel has a graduated dial for gauging
table movement along the related axis.
The X- and Y-axis graduated dials (see Figure 16)
are in increments of 0.001"—with one full rotation
equal to 0.0625".
Figure 16. X- and Y-axis graduated dials.
The Z-axis graduated dial is in increments of
0.0005"—with one full rotation equal to 0.03125"
(see Figure 17).

-20-
To use the Z-axis graduated dial, multiply the
increment amount shown by the number on the
dial. For example, if the 50 increment mark is
aligned with the indicator mark, then multiply
0.0005" by 50, which equals 0.025"
Vertical Head
Movement
When using the mill in the vertical configuration,
the head can be tilted 50° left or right. By moving
the ram, the spindle can be positioned a maxi-
mum of 12 ⁄ " from the column (spindle centerline

3. Manually adjust the head tilt to the correct
angle for the operation, then re-tighten the
locking cap screw.
Note: Use the scale shown in Figure 18 to
gauge the angle. For more accurate results,
use a precision protractor between the spin-
dle and the table.
