Precision Pins: Gyroscoping/Directional Pins

Serving the Aerospace Industry with Extreme Precision Products

Precision Pins: Balancing the Future

Directional precision pins (with tolerances down to .000003” [.000076mm] on OD’s/ID’s and .000010” [.000254mm] flatness) are manufactured by our experienced precision machinists with specialized and custom equipment. In most cases, precision grinding and lapping is required to maintain the finishes and tolerances required by our customers.  Many of the precision pins manufactured by the machinists at GLE-Precision require special tooling or fixturing to hold, grind or inspect the part.  Some of the surface finishes we are required to hold today could basically be scratched by grains of dust.  The highest level of care must go into manufacturing every step of the way. 

Gyroscopes and Precision Pins

Gyroscopes are commonly used in aircraft instrumentation such as altimeters, compasses, and turn coordinators. These instruments contain a wheel or rotor which is rotating at a high RPM (revolutions per minute) which gives the system properties of rigidity and precession.  The gyro (rotor) can be pressure or vacuum driven.  A special pump on the engine drives the gyro (rotor).  Many flight instruments today have a mechanical gyroscope encompassed within the system.  The precision pins that GLE-Precision produces are used in directional/gyroscoping applications, providing directional support as a components in a much larger system.  Major Airplane manufacturers trust the lives of the pilots and many others to the ultra-precise central guidance precision pins produced by GLE-Precision.
