Custom
Gages
Have
a tough gaging problem? Mikes and calipers just don’t cut it? Send us
a part print today! We have tackled hundreds of problems for our customers,
and we are anxious to solve yours as well. Here are a few examples...

The
Customer:
Automotive industry
The
Problem:
Run-out and surface-finish need to be verified on both the main
and journal diameters of a crankshaft.
The
Solution:
We designed this assembly around a granite surface plate for maximum
accuracy. As a motor rotates the part, two pivoting Arnold OD gages,
coupled with LVDT probes, relay run-out information to a pair of
readout columns. With the crankshaft already in place, the operator
then analyzes surface finish using an attached profilometer. Since
this gage is installed on the shop floor, gaging time is reduced
from over two hours (on an expensive lab CMM) to under 5 minutes.
As a result, the customer is now able to make process modifications
on the spot, eliminating expensive scrapped parts.

The
Customer:
Automotive industry
The
Problem:
An automotive parts supplier needs to check backlash. The gage must
provide variable data, and be versatile enough to analyze several
universal joints on a series of steering columns.
The
Solution:
This gage utilizes a precision radial encoder and weights to accurately
determine backlash. To accommodate the many positions and lengths,
the encoder assembly slides along a pair of precision bearings.
A series of interchangeable tooling locates each part and allows
backlash to be checked at several points. This tooling is expanded
upon to gage new parts as needed.

The
Customer:
Aerospace industry
The
Problem:
Features of a jet-engine airfoil must be checked on the shop floor.
The solution must be quick, foolproof, and withstand a salty, harsh
electro-chemical machining environment.
The
Solution:
Using floating reed assemblies and carbide tipped fingers, this
gage instantly verifies the part. Results are displayed on digital
indicators, which could easily be integrated in an SPC system. Another
advantage is loading and gaging time. With this gage it takes just
seconds, versus several minutes on a CMM. This gage was manufactured
from ammco and stainless steel for maximum corrosion resistance.

The
Customer:
Computer industry
The
Problem:
The following features of a printer component must be inspected:
3 different diameters, 4 lengths, and run-out on both sides. Speed,
variable data, and integration into an SPC system are among the
requirements.
The
Solution:
Arnold Gauge met and exceeded these challenges with this solution.
All features are checked using floating reed spring units and LVDT
probes. After the part is located in vees, the lengths and diameters
are instantly verified. The operator then simply rotates the part
to inspect run-out. Results (accurate to .0001") are clearly displayed
on the adjacent monitor, and recorded in SPC software.
