MicroForm µFG150 Gage

MicroForm Model µFG150 “Roundness” Gage

ABTech MicroForm articulating arm roundness gages bring speed, ease and confidence to the shop floor or QC lab for measuring tight geometric tolerances with ultra-precision accuracy and repeatability.

MicroForm gages are ideal for in-process geometry measurements of shafts, bearings, gears, pistons, turbocharger and other precision machined or stamped parts; incoming inspections for vendor compliance; optical lens inspection; manufacturing process control and quality control lab analysis. The most common geometric form measurements are included; runoutroundness, flatness, concentricity (in and out of plane), parallelism and perpendicularity.

MicroForm Articulating Arm Roundness Gages – Product Specifications

Accurate and repeatable

An ultra-smooth, maintenance-free rotary air bearing with an available direct drive provides an ultra-precision reference axis. A responsive lever-type probe with nearly perfect linearity combines to provide overall system accuracy better than 5 µ” (0.125 µm).

Stable and reliable

The air bearing is recessed in a metal base for the µFG100 and µFG150 models, and a granite base for the µFG200, providing excellent thermal and vibration stability. Common contributors to measurement errors have been purposefully engineered out of our gages, giving you the confidence that the results are from the part alone, and not “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 signal with the angular position of the rotary table for pin-point accuracy.

Quick part and probe setup

Tilt and center worktables have very fine adjustments to allow operators 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 time and frustration in getting parts set up. An articulating gage arm lets you rapidly switch between a diameter and a face, or from an OD to an ID. No wasted time wrestling with locks or swivel joints. The gage stand is mounted on a linear slide with dual-action micro-knobs for coarse and fine adjustments.

Easy-to-use software with touchscreen navigation

MicroForm’s intuitive measurement program features two simple views on 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 can be automatically removed during a measurement or easily edited out using our drag and exclude feature on the results plot. Analyze part harmonics, slope and lobing on the results screen or export the data for statistical process control (SPC).
