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.

Full Product Line Offering

The MicroForm gage line is designed to address the gamut of metrology needs. Whether measuring small parts requiring custom fixtures, large diameter heavy-weight parts, tall shafts with deep bores, bearings, pistons, turbo-chargers and other precision machined or ground parts, we have a gage that can handle it.

Unique Large and Tall Part Capabilities

These gages are turnkey systems with working load capacities up to 6,000 lbs and worktable diameters up to 48" without compromising accuracy or repeatability. With our counterbalanced tower designs, the sky is the limit (almost) for vertical height of the probe.

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.

Harmonic Analysis Results

The flexibility to analyze part harmonics (slope and lobing optional) right on the results screen. Or, export the data for statistical process control (SPC).

Features & Benefits

  • Air bearing rotary table providing ultra-smooth, repeatable and maintenance-free operation

  • Highly responsive lever-type probe with excellent linearity over the full travel

  • Real-time operating system with FPGA processing platform and signal conditioners eliminating resource conflicts typical with systems running on PC’s

  • Gage stands designed for precise, stable movement while optimizing ease of use

  • Standard tilt & center worktable to center and level parts to the bearing’s axis of rotation reducing eccentricity, increasing accuracy of results and reduces time and frustration during setup of the part for measurement

  • Intuitive navigation for shop floor use as well as full function analysis for quality control labs

  • Step-by-step instructions for novice operators without reducing efficiency for experienced users

  • Touch screen color monitor

  • Easily customizable outputs and display settings such as filter, plot scale, units, and analysis type

Options

  • Optional integrated motor drive (standard on µFG100 through µFG200 models)
  • Universal style gage stand on a T-slot base (replaces the articulating arm style)
  • Second gage stand and probe with dual probe software upgrade
    (not available on µFG100 )
