methods and shimming. Adjusting the yaw of the machine is not necessary and beyond the
scope of the manual. The methods of measuring the pitch and roll are described below.
1. Place a precision parallel bar on the table. (pictured bar is flat/parallel to .0001”over 6”)
2. Run the dial test indicator along the parallel bar noting the change in pitch.
3. Do the same for the roll.
Figure 9: Measuring pitch and roll of table.
4. If for any reason the table must be removed or replaced it is important the table is
properly installed to insure accuracy. This will require the loosening and/or removal of
sixteen slide screws and the four screws which attach the table to the lead nut. Figure
10a shows the lead nut screws. Figure 10b shows the area to place the shim.
