How to Use Gauge Blocks
This section describes an example of typical usage (assembling of a reference
gage with a desired length) and explains the wringing process.
2.1
Example of Typical Usage (Assembling a Reference
Gage with a Desired Length)
Assemble a reference gage with a desired length by wringing Gauge Blocks
together.
The assembled reference gage can be used for the zero setting for measuring
tools and for comparative measurement.
As an example, this procedure explains the assembly of a 37.785 mm length
reference gage.
■ Precautions about the assembly
y Use as few Gauge Blocks as possible for the assembly.
y Select thick Gauge Blocks as much as possible.
y Begin by selecting a Gauge Block where the last digit of the target dimen-
sions matches the last digit of the nominal size.
NOTICE
If you select the same Gauge Blocks each time you assemble them, those Gauge
Blocks will wear down faster than the other Gauge Blocks.
Make a di󰀨erent combination each time so that Gauge Blocks will wear down at the
same rate.
The following shows an example assembly.
