2. Applied Operation
2
Touch the surface A of the block gauge
A
with the probe of an electric micrometer or dial gauge and
align the micrometer hand to read “0.” Simultaneously reset the counter unit.
When the display resolution is 0.001 mm
3
Next, move the table away from the probe and remove the block gauge
A
, move the machine table
again, touch the surface C of the block gauge
B
with the probe of the electric micrometer or dial gauge,
and move the machine table until the meter reads “0.” Be sure to make a note of the difference between
the displayed value on the counter unit and the length of the block gauge
A
, because this is the linear
error to be compensated.
An example of setting the amount of linear compensation is shown below.
Note: Do not change the probe height h until finished measuring.
