Edmunds Air Gages makes complete, integrated air gaging systems: amplifiers, tooling, setting masters, connectors and accessories. The Edmunds Gages Air gaging is a two master solution assuring linearity and accuracy.
The adjustable magnification of the Edmunds Gages Air back-pressure bleed system makes adaptability to many applications effortless within broad ranges of tolerance.
- Inside and Outside Diameters: Edmunds Air Plugs and Edmunds Air Rings are most commonly used for measuring the size and form of inside diameters and outside diameters. Two nozzle air plugs, with nozzles diametrically opposed, are often used for internal measuring, and two-nozzle air rings are used for external dimensions.
- Averaging : Multiple nozzles are equally located about the circumference of the air tool to allow for average size measurement. Commonly used for thin-walled or out-of-round parts – four, six, or more nozzles are utilized, depending on the tool size.
- 3-Point Out-of-Round (Lobing) Out-of-Round: Air tools can gage a part for roundness. For two-point out-of round conditions, a standard two-nozzle air tool can be used. If lobing exists in the part, an odd number of nozzles must be used, depending on the number of lobes
- Straightness A common application of air gaging is to dynamically measure the straightness or “bow of an inside diameter. In this case, a custom designed air plug makes verifying a part’s straightness simple and fast. (A straightness air plug cannot measure diameter).
- Squareness to determine squareness of a part, for example a bore to a face, air nozzles configured as a “z are used with dynamic measurement to change the back-pressure from square to outof-square conditions.
- Taper Angle variation of tapered surfaces is commonly checked with air gaging as the difference of two diameters.
- Flatness To measure flatness, an air nozzle is mounted within a stationary platen. The part is then moved across the nozzle. This process provides a convenient, quick method to accurately gage flatness.
- Matching A specified clearance between two mating parts is often required to assure proper part operation. The Edmunds AccuSetter amplifier allows for the individual display of the bore size, the shaft size, and the clearance between the two parts. Operators need only observe the clearance display to determine if the two components have the required match dimension.
