Air Gages

Sliced Bread And the Limits of Air Gaging

"Air gaging is the greatest thing since sliced bread," a friend once told me.  And he was right — air gaging is good.  It's fast, high resolution, non-contact, self-cleaning and...

Checking Nozzle Balance

1. Calibrate the air gaging system using the max and min masters in a normal manner. 2. Orient the tool with a horizontal centerline so the jets are situated vertical...

Checking Air Gages Centrality

1. Calibrate the air gaging system using the max and min masters in a normal manner. 2. Orient the tool with a horizontal centerline and with the jets located horizontally...

You Won’t Err With Air

It is perfectly natural that machinists should have an affinity for mechanical gages. To a machinist, the working of a mechanical gage is both straightforward and pleasing. Air gages, on...

Flexibility of Air Gaging

Previously, we touched on several applications where air gaging is particularly practical. These include relational, as opposed to dimensional, measurements, such as distance between centers, taper and concentricity. Along with...

Air is Free, but Not Carefree

We concluded that air gaging represents the method of choice for most high-resolution measurements on large production runs. While quite durable and reliable compared to mechanical gages, air gaging is...
