MicroForm Roundness Gages
Quickly & Easily Measure Precision Geometric Forms with Unmatched Performance
The foundation of our MicroForm line of roundness gages is an ABTech designed and built precision air bearing rotary table providing a stable, robust and maintenance free reference axis with certified system accuracy better than 5 millionths of an inch (5m” or 0.125 mm).
Our powerful yet intuitive software simplifies navigation, and the touch screen interface displays the results in a straight
forward and familiar way. Combined, these ease-of-use features allow operators of all skill levels to take exacting measurements on the shop floor or in the QC lab. Standard features include auto-interrupt, harmonic analysis, polar and strip chart reports, and pdf printable report.
MicroForm gages measure roundness, runout, flatness, concentricity (in and out of plane), parallelism, and perpendicularity. A unique analog style TIR meter simplifies part alignment and provides a quick in-process shop floor check.
MicroForm gages are deployed for a variety of manufacturing and quality functions including in-coming inspection for vendor compliance, in-process tolerance confirmation, manufacturing process control and quality control.
All models let you rapidly switch from a face to a diameter feature or an ID to OD. The articulating arm and probe mount features detents at 90 degrees for quick and stable movement so you will not waste time wrestling with locks or swivel joints. The MicroForm μfg150 and μfg200 models further speed the measurement process by offering multiple gage stand configuration options and dual gage head capabilities. Or for further flexibility, replace the articulating arm with two universal style gage stands on a T-slot base.

Unique Large and Tall Part Capabilities
Main Screen with Analog Style TIR Meter
MicroForm’s intuitive software features two simple views that clearly lay out access and navigation. On the left sidebar of the main screen you will find all the form options are always visible. The analog style TIR meter is large and easy to read. For the novice operators, on screen “step by step” instructions are available. The touch screen allows quick navigation between main and results screens.
Results Screen with Polar Chart
The results screen and large polar chart are uncluttered and easy to read. You can quickly print or save a pdf file of the data. And to provide remote file storage and enterprise connectivity, each PC includes an Ethernet network card. Auto interrupt feature allows automatic exclusion of interrupted surfaces or easily edit out using our drag and exclude feature.
