Introduction to Air gauging

In the U.K. the two most common makes of air gauge are Federal and Mercer. Federal is a one zero setting ring system and the unit is calibrated using a master jet kit. Mercer is a Min/Max two ring system, to set up range. For both makes we can supply new or reconditioned units.

We also sell and repair other makes such as, Sheffield, CEJ, Sigma, Coventry Gauge, Neerburding, IBR and Etamic.

Dependability and Stability - Two characteristics that spring to mind

Fast/Accurate/Reliable - Air flow cleans the part. Response of the meter is repeatably fast

Non Contact - Wear is kept to a minimum so tooling lasts longer and does not mark the component. This also makes them useful for checking soft/polished and delicate parts.

High Magnification - Measure well beyond the scope of mechanical gauges

Robust - Will take abuse and dirt in a production environment

Easy to use - Minimum training required

Flexible - Can be used in process and through to final inspection

Tooling - Made to order and can measure many different features, for example when measuring a bore it will also indicate out of roundness, ovality, taper and barrel shape.

Features Gauged - Through/blind/counter/deep bores, outside/shoulder diameter, parallelism, straightness,taper,ovality,flatness, squareness, thickness, clearance and interferance (match gauging)

Special fixtures - Air Gauging can also be applied to special fixtures, to gauge unusual and more than one feature at a time

Getting started - The bare minimum required is a gauge unit, air plug and setting ring
