Digital Gauging Probes

Application Story Flatness

The Challenge

In Electronics and Automotive components, the flatness of a part may be a critical feature. Everything from Cell Phone glass to a Brake Disc may carry sub-micron tolerances for flatness, so they may properly fit inside a larger assembly.

For this, several points over a small surface area must be checked, with high accuracy being a key feature. Non Contact 3D or Imaging solutions can be used, but with a high cost and possible loss in accuracy.

The Solution

• Solartron Digital Gauging Probes provide excellent performance for Flatness applications due to the following features:
• Class leading resolution of down to 0.01 µm. This means even the slightest variability between points will be measured.
• Repeatability of up to 0.015 µm. Measurements will be consistent from part to part.
• Low Tip Forces: Solartron offers low tip forces of 0.30N with its Feather Touch probes and 0.03 to 0.05N with it’s Ultra Feather Touch probes, meaning the surfaces being checked won’t be scratched or damaged. In addition, the low forces mean a part won’t be “lifted” or shifted during measurement.
• Measure Multiple points easily: With the Solartron Orbit® 3 network, up to 150 points can be allocated instantaneously and output to a PC or PLC. Flatness or “Max - Min" can then be calculated using an Excel Pack or other software. 
• Lower Cost: A Solartron Gauging Probe provides significantly lower cost per point compared to a costly imaging system or 3D scanner, with higher repeatability and easier set up.
