L-703SP - How It Works
Performing a Flatness Quick-Check on a Line-Segment after Lapping
One of the annoying parts of using electronic levels when re-surfacing a surface plate is you have to shoot the entire plate
for flatness to see how the lapping process is going. This is a waste of time! With the L-703SP Surface Plate Calibration
Systems, you can do quick-checks of a single line segment in about 5 minutes to see how much the flatness error has been
reduced. Typically, you’ll pick the line segment with the highest flatness error and focus on it as you lap the plate.
Here is the procedure to do a quick-check of a line segment for flatness after you have finished the lapping and cleaned
the plate.
Note - you don’t really need to clean the entire plate but just the area that you will measure.
Step 1 - Set Up Laser Line & A-703SP-LM
Select the line segment you want to measure
and select the matching length for the
A-703SP-SE Straight Edge ruler. Use the
corner/midpoint locating tool to set up the
straight edge as shown above on pages 35, 41
or 42.
Then place the L-703SP-LM Laser Fixture on
the straight edge as shown above.
