Articulating Arm  –  Single Probe

(Max Part Size: 8” dia. x 12” tall, Max Part & Fixture Weight: 60 lbs)

Quickly and easily measure precision geometric forms with unmatched repeatability.  Our roundness gages incorporate an ABTech designed and built air bearing rotary table that delivers ultra-precision results. A powerful yet intuitive user interface simplifies navigation, displaying the results in a familiar way. These ease-of-use features allow operators of all skills levels to take exacting measurements on the shop floor or in the QC lab.

All MicroForm gages measure roundness, runout, flatness, concentricity (in and out of plane), parallelism and perpendicularity. They are used for a variety of manufacturing and quality functions including, in-coming inspection for vendor compliance, in-process tolerance confirmation, manufacturing process control and improvement, and quality control and part analysis.

Features & Benefits

Accurate and Repeatable

An ultra-precision air bearing rotary axis is the foundation for all MicroForm gages. Combined with a highly responsive lever-type probe with nearly perfect linearity, our gages carry an overall system accuracy certification better than 5 millionths of an inch (5μ” or 0.125 μm). With no mechanical contacting parts to wear or create drag, air bearings produce virtually no friction. This translates into ultra-smooth, repeatable and maintenance-free operation. For statistical process control (SPC) and traceability, results and graphical charts can quickly be saved, printed, converted to PDF, or exported using the available Ethernet network connection.

Stable and Reliable

Frustrated by frequent measurement errors? That’s why our platforms are engineered to minimize the need to take repeat measurements. For added shop floor durability, and to maximize thermal and vibration stability, each air bearing is recessed in a finish machined metal base – with no branded plastic housing. And minimal cabling and connectors help reduce electrical interference that could distort your measurements. With such a robust design, you can be confident that your measurement result is from the part alone, and don’t include “noise” from outside influences.

Quick Part and Probe Setup

Our industry-best tilt and center worktable with very fine adjustments allow operators to precisely level and align parts to the bearing’s axis of rotation, reducing eccentricity. The spherical seat design maintains the part’s center point when leveling, saving you time and frustration in setting up the part for measurement.

An articulating gage arm lets you rapidly switch between a diameter and a face or from an OD to an ID. You won’t waste time wrestling with locks or swivel joints. Visible linear scales on both the horizontal stage and vertical post allow pinpoint alignment of the probe tip to the measurement surface. The articulating arm and probe mount feature detents at 90° for quick diameter or face access and drift free positions in between.

To further speed the measurement process, our MicroForm µFG150 and µFG200 models offer multiple gage stand configuration options and dual gage head capabilities. Add a second side mounted gage stand, or for further flexibility, replace the articulating arm with two universal style gage stands on a T-slot base.

Familiar User Interface with Touch Screen Navigation

We’ve designed our measurement program to display results in a fashion that is familiar for shop floor operators while providing full function analysis for quality control labs. In the case of a user interface often less in more. MicroForm’s intuitive software features two simple views on a large color touch screen monitor, delivering quick and easy results whether you’re a novice or experienced operator. Toggle between the main setup screen with active analog and digital runout meters, to the results screen with graphical polar and linear charts. A sidebar menu of all the form options along with measurement results are always visible And for novice operators, on screen “step-by-step” instructions are available. (Learn more about MicroForm software.)

Unique Dedicated Processing Power for Fast Measurements

Our gages are driven by a “real-time” operating system with dedicated FPGA processing platform and signal conditioners. These are the workhorses for performing the measurement algorithms, eliminating resource conflicts typical with systems running on PCs. The gage’s dedicated processor results in high speed data acquisition and instantaneously synchronizes the indicator displacement with a high resolution encoder for pin-point accuracy. This powerful processing platform not only provides tremendous system performance but also permits future system enhancements without the cost and downtime associated with hardware obsolescence.

A Spectrum of Analysis Functionality

To ensure quick and accurate measurements, surface interruptions can be automatically removed during a measurement or easily edited out using our drag and exclude feature. You also have the flexibility to analyze part harmonics (slope and lobing optional) right on the results screen or export the data for statistical process control (SPC).

User definable system preferences for customizing output and displays are readily accessible through the configuration button. Select from four reference circle types: Least Squares Circle (LSC), Minimum Zone Circle (MRS), Minimum Inscribed Circle (MIC), and Maximum Circumscribed Circle (MCC), Gaussian filter settings, units of measure, and other options to match your part drawing’s requirement.

Quickly print or save a PDF file to share the measurement results and graphical charts and document traceability. And each PC includes an Ethernet network card to provide remote file storage and enterprise connectivity.

MicroForm™ Software

for Precision Measurement

A straightforward interface which increases productivity, streamlines training, and offers the highest degree of operator flexibility. The full functionally is made easy so operators of every skill level can use our gages. The maximized interface accommodates different skill levels with on screen “step by step” instructions that don’t interrupt an experience user. All MicroForm gages offer a dual probe option to enhance the measurement process.
