Squaring Chuck with
Table
The axis of the chuck was set 90° to the table at
the factory. This ensures boring operations will be
horizontally squared in the workpiece.
If boring holes are no longer accurate on a
workpiece, as shown in
Figure 37, refer to
Troubleshooting on Page 30 to rule out other
solutions first, then perform the following proce-
dure to realign the chuck and table.
