Air
plug gages are used for testing cylindrical through bores or blind
bores. The plug gage bodies are equipped with two opposing measuring
jets which record the measured value without contact. This arrangement
allows the diameter, the diametric roundness and the cylindricity
of bores to be calculated using a single jet air plug gage.
The
diameter is measured immediately after the air plug gage is introduced,
while the diametric roundness deviation can be tested by rotation
around 180° and the cylindricity by movement in a longitudinal
direction.
The
maximum measuring range of the air plug gages is 76µm/.003in.
Air
plug gages are furnished in high chrome stainless steel or chrome
plated versions and, if required, with a shut-off valve to conserve
air consumption.
The
air tooling long service life is due in part to hardened measuring
jets which are recessed relative to the generated surface of the
measuring body and are, therefore, protected against damage.
The
standard Mahr Federal air tooling is compatible with the complete
line of evaluation units. These include Dimensionair, uDimensionair,
832 PE, 1840 PE, and 1841 PE signal sharing column. Air/Electric
convertors for interfacing to gaging computer systems are also
available.
Special
air gage designs for measuring taper, straightness and other applications
are available. Contact Mahr Federal.
For
applications greater than 1000 feet, special calibration is required.
Air
Snaps Improve Shop Floor Measurement Performance
Mechanical
snap gages have been the gage of choice for measuring OD's as
parts are being machined. They are an easy to use, fast and reliable
method to check the OD of the part while in the machine. But today
the tolerances on many OD’s are shrinking. What was once
0.002” is now 0.001” or even 0.0005” on diameters
4” or larger.
Once
these tolerances are specified the mechanical snap starts to meet
it limits. Because of the mechanical limits and resolutions of
the readouts they just don’t have the capabilities to meet
GR&R performance required. This is where the Air Snap takes
this measurement process to a new level.
Because
the air snap is made to the size to be measured with no moving
parts, the design is far superior for the application. Special
configurations allow for placing the jets close to shoulders or
multiple measurements in a single gage. A combination of high
performance and versatility make an Air Snap the gage that will
improve your measurement process.
