ABTech fills the void for measuring roundness of taller parts without the added expense or programming expertise required on other gages with CNC controlled axes. With easy-to-use manual probe setup and our full software package MicroForm mini-tower roundness gages keep it economical to purchase, and simple to operate.
MicroForm™ Minitower Roundness Gages – Product Specifications
Accurate and repeatable
An ultra-smooth, maintenance-free rotary air bearing with an available drive provides an ultra-precision reference axis. A responsive lever-type probe with nearly perfect linearity combines to provide overall system accuracy under 5 µ” (0.125 µm).
Stable and reliable
The air bearing is mounted on an inspection grade natural granite and welded 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 doesn’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
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. ABTech’s mini-towers are counterbalanced for 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 and accommodates parts up to 36″ in height. The main tower is encoded so the vertical position can be captured directly into the MicroForm measurement software.
Fine adjust knobs and visible linear scales on both the horizontal arm and secondary vertical arm allow precise alignment of the probe tip to the measurement surface. Additional portable gage stands can be used on the granite surface plate.
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).
