Tips to Calibrate Thread Gauge

Tips to Calibrate Thread Gauge The thread gauges
are one of the crucial elements of any mechanical
design in critical applications. Though many
tend to overlook the thread gauge application,
the complex science behind the simple element is
fundamental. A large spread of application is
required to even assemble the threaded part into
the whole machinerys assemblage.
The way it is installed determines operation
conditions, even the strength of the components
of the machinery. That is why Thread Gauge
Calibration is essential.

How-To Thread Gauge Calibration You are
required to select the corresponding master plug
confirming the size of the part. Ensure that it
is calibrated and the integrity of the piece is
top- notch. Lubricate the plug using light
viscosity oil. Now, you are required to clean
and inspect ring gauges for any
impurities. Remove the sealing wax using a
knife. Turn the ring gauge counter- clockwise,
and then adjust the screw clockwise. Turn the
ring gauge on the setting plug so that one
thread goes beyond the last thread of the
plug. Modify the screw counterclockwise. Fasten
the ring situated on the setting plug. Continue
doing it until you discern a slight drag between
the two gauges. This procedure has to be
repeated quite several times. Tap the ring with
a hammer to check whether it has been properly
seated. If not, repeat the previously mentioned
step. Now, swivel the ring gauge in a truncated
section at the front of the set plug.
The ring should be situated properly if you
notice a "shaky" movement, then it is an
indication that the flank angles are worn out,
which needs to be replaced. Discard the set
plug situated from the ring now turn the ring to
the set plug of 1 to 2 threads at the front. You
will notice resistance, but keep rotating it to
the truncated section. Now repeat the process on
the other side of the ring gauge. The resistance
noticed while doing this should be the same on
both sides. Measure the minor diameter of the
ring gauges with bore gauges, internal measuring
machine, or even fixed limit GO/NOGO plug
gauges. Seal the locking and adjust screws with
wax so that tampering cannot be done, and voila,
your gauge calibration is done.

Conclusion We recommend that the set plug
should be readily available for inspection as it
is heavily utilized. The affected parts should be
removed as it could create a negative impact on
the functionality. If you wind the calibration
process tough, we suggest taking help from
professional calibration services. To Know More
