17. Mount the Dial Indicator Mount and Precision Dial
Indicator.
18. Adjust the tip of the Precision Dial Indicator to
strike the equator of the ball. Make sure the
indicator is not pegged (i.e. the small needle on the
gauge near the centre of the Dial Indicator is
around the halfway mark).
The Precision Dial Indicator is very sensitive and
care should be taken not to lean or touch any part
of the system while adjusting the indicator or X,Y
Ball Centring tool.
19. Zero the Precision Dial Indicator.
Note: For fine measurements, the Precision Dial Indicator may not be accurate until after the first
movement.
20. Return to the X-Ray and Motor Controller window.
21. Use the Rotation setting to rotate the ball 360° (180° at a time). Re-zero the Dial Indicator, if
necessary. Watch as the ball is rotating to ensure that the tip of the Precision Dial Indicator is
touching the ball at all points of rotation and that it is not pegged.
Center the Ball:
22. Use the Rotation setting to rotate the ball 180°.
23. Watch the Precision Dial Indicator as the ball rotates. Note the reading of the Precision Dial
Indicator after 180° of rotation (e.g. .0004").
The objective is to adjust the ball so that, after the adjustment, the Dial Indicator reads half of
the original reading (e.g. .0002").
To do this:
24. Use the tool’s adjustment key to carefully turn the 2 adjustment screws that are aligned with
the Dial Indicator - turn the screws until the Dial Indicator reads half of the original reading.
