MicroForm™ Large Capacity Roundness Gages

Print Friendly

ABTech’s MicroForm system is unique in the industry having been designed for full scalability to perform ultra-precision form measurements on even your largest parts. MicroForm large capacity roundness gages are turn-key systems featuring heavy duty air bearing rotary tables with working load capacities up to 6,000 lbs and worktable diameters up to 48”. And the sky is the limit (almost) for vertical height of the probe using our counterbalanced tower designs.

MicroForm™ Large Capacity Roundness Gages – Product Specifications

Accurate and repeatabMicroForm Large Capacity Roundness Gages - Model MFG450le

An ultra-smooth, maintenance-free large capacity rotary air bearing table with an available motor drive provides an ultra-precision reference axis. Standard single lever-type probe or optional dual probes with nearly perfect linearity contribute to an overall system accuracy under 10µ” (0.250 µm), even better at under 5 µ” (0.125 µm) for systems up to 2,000 lbs in capacity.

Stable and reliable

The air bearing table is mounted on an inspection grade natural granite surface plate and welded structural steel base for passive vibration isolation. Common contributors to measurement errors have been purposefully engineered out of our gages, giving you the confidence that your measurement results are from the part alone and don’t include “noise” from outside influences.

State-of-the-art technology for fast measurements

A “real-time“ operating system in the MicroForm controller eliminates resource conflicts typical with systems running on PC’s. The processor provides high speed data acquisition and tight synchronization of the indicator with the encoder for pin-point accuracy.

Quick part and probe setup

Full sized counterbalanced towers are configurable based on your tallest part and provide easy motion while protecting the probe and your parts from accidental damage.  A secondary vertical probe arm provides easy access to ID surfaces in deep bores. The main tower can be encoded so the vertical position can be captured directly into the MicroForm measurement software.

Fine adjust MicroForm Large Capacity Roundness Gages - Model MFG450 Vertical Gage Armfeatures on both the horizontal and vertical arm allow precise alignment of the probe tip to the measurement surface from the tower – as opposed to out at the gage head which can be difficult to reach on large parts!  Additional gage stands mounted to the granite or as portables on the top surface can be used with the upgrade option for a dual probe configuration.

Heavy duty tilt and center worktables have very fine adjustments to align parts to the bearing’s axis of rotation, reducing eccentricity. The spherical seat design maintains the part’s center point when leveling, saving the operator time and frustration in getting set up. Tip tilt tables with 3 point leveling are included on the largest gages.

Easy-to-use software with touchscreen navigation

MicroForm’s intuitive measurement program features a simplified two-screen layout and is coupled with a large color touchscreen monitor to deliver results quickly and easily whether a novice or experienced operator. (learn more about MicroForm software)

Capable analysis functionality

Surface interruptions are automatically removed during measurements or easily edited out using our drag and drop feature on the results plot. Analyze harmonics, slope and lobing right on the results screen or export the data for statistical process control (SPC).
