ABTech designs and manufactures turn-key MicroForm™ gage systems for performing ultra-precision form measurements. Each gage incorporates our proven air bearing technology and the latest electronics to deliver ultra-precision results quickly and easily. The MicroForm system was designed to be fully scalable for 6” up to 36” diameter tables, and larger if necessary!
The most common form measurements are included in all MicroForm gages; covering roundness, flatness, concentricity (in and out of plane), parallelism and perpendicularity. We've also incorporated our novel "live RunOut" feature for quick in-process shop floor TIR/FIM checks. There's even an optional Wedge (aka "Edge Thickness Variation" or ETV) measurement module that extends the system's automated measurement and analysis capabilities for applications specific to the optics industry.
State-of-the-art technologies are featured throughout the gage system. The metrology platform combines an ultra-smooth, maintenance-free rotary air bearing with an optional integrated direct drive as the reference axis. The air bearing table is embedded in a cast iron base for the µFG150 tabletop model or mounted on an inspection grade natural granite surface plate and passive vibration isolation base for larger systems. Reliable and repeatable.
A T-slot plate on the µFG150 model provides unlimited positioning options for the inspection quality gage stand and allows for the use of multiple stands. Infinite flexibility in gage head orientation is made possible through our unique articulating gage arm design.
Tilt and center (tip/tilt) worktables allow very fine adjustments to align parts to the bearing's axis of rotation, reducing eccentricity. Our spherical seat design maintains the part's center point when leveling, saving the operator time in setting up the part for measurement.
Common contributors to measurement errors in competitors' gages come from internal electrical components that are sources of thermal and/or vibration interference. These have been purposefully engineered out of the MicroForm measurement platform. The motor drive amplifier, power supplies, encoder interface and other electronic hardware are installed in a separate metrology controller and therefore isolated from the work piece. This gives you the confidence to know that your measurement result is from the part alone, and doesn't include "noise" from the rest of the system.
To complement the stable metrology base design, a "real-time“ operating system with dedicated FPGA processing platform and signal conditioners are included in the metrology controller. These are the workhorses for running the measurement algorithms, eliminating resource conflicts typical with systems running on PC’s. The on-board processor results in high speed data acquisition and instantaneously synchronizes the indicator displacement with the high resolution encoder for pin-point accuracy. The processing platform not only provides tremendous system performance but also permits future system enhancements without the cost and downtime associated with obsolescence of electronic hardware.
ABTech’s MicroForm measurement software offers intuitive navigation for shop floor use, and full function analysis for quality control labs. On screen "step-by-step" instructions assist the novice operator through each measurement in a way that doesn't reduce the efficiency of experienced users. Customizable displays and output options are built in to meet your particular needs.
Quickly save, print, convert to PDF, or export and share measurement results and graphical charts using Ethernet network connections for statistical process control (SPC) and traceability.
