2 Removing burrs from the measurement surface with a Ceraston
(part No. 601644 or No. 601645)
1 Wipe the measurement surface of the Gauge Block and the surface of the Ceraston
with lens cleaning paper soaked in solvent (such as normal heptane), and then wipe
the surfaces dry with a dry portion of the paper.
Tips
For wiping, use lens cleaning paper or other material which does not leave paper
bers.
2 Place the measurement surface of the Gauge
Block with burrs facing towards the Ceraston.
3 While holding the Gauge Block by its sides
with your thumb and middle nger, lightly push
the upper surface of the Gauge Block with your
index nger to give a back and forth motion to
the Gauge Block 10 times on the Ceraston.

Tips
• If the Gauge Block is too thin to hold (a
nominal size of 3 mm or less, for example),
using an eraser or other rubbery object to
hold down the Gauge Block may help apply
the force uniformly, as shown in the gure
on the right.
• The Gauge Block will smoothly slide on the
Ceraston as long as there are burrs. The
Gauge Block will start to stick to the Cer
-
aston as burrs are removed.
3 Repeat steps
1
and
2
to check and remove burrs on all the Gauge
Blocks to be wrung.
Tips
If burrs cannot be removed even by repeating steps
1
and
2
, the Gauge Block
cannot be used as a reference gage. Purchase a new Gauge Block with the same
nominal size as a replacement.
