Alignment
The next step is to mount the A-axis parallel with the X-axis. This means the pitch and yaw of
the A-axis will need to be adjusted properly. Follow the steps below to setup the rotary axis.
Figure 20: Run out check
1. Mount the rotary table on the XY table as parallel as you
can by eye. Tighten the screws by starting with the front
right, then back left, then back right, and then front left.
This will help to insure that the mounting plate is level.
2. To check the A-axis pitch, indicate at the bar at the chuck
face by moving the indicator lever overtop of and in front of
the bar. Then slowly move the Y-axis toward the front of the
machine and as the indicator drags over the bar note the
highest point on the indicator as in the figure
3. Repeat this process an inch or two down the bar. Note the
high point, as in figure 22.
4. Compare the points. If the first point is higher than the
second then the bar is sloping down. If the second point is higher then the bar is sloping
up.
