ZeroTouch non-contact metrology platform

A non-contact 3D brake inspection system that measures complex geometries and performs defect detection.

Non-contact 3D Brake Inspection System

The ZeroTouch® brake inspection system is a non-contact brake inspection system that generates a 3D point cloud, providing manufacturers with real-time metrology and inspection data to optimize production processes, detect defects, and improve ROI.

Increases Accuracy

Increases Throughput

Detects Defects

ZeroTouch measured the entire part surface, generating a high-density, micron-level point cloud.

ZeroTouch executed the inspection plan in just 20 seconds versus the tactile methods, which took 1 minute.

ZeroTouch measured all surfaces in 3D and identified defects too.

Benefits of Consolidating Metrology Operations

Automated metrology platforms not only ensure high quality finished goods, these high speed solutions also lower total cost per part by consolidating multiple metrology operations into one system.

Improving Long-Term Performance of Metrology Systems

In challenging manufacturing environments, adjustability, calibration, and monitoring are key influences on the long-term performance of automated metrology systems installed in uncontrolled environments.

Speed Wins in Contact vs. Non-Contact Surface Profiling

In surface morphology inspection, non-contact optical methodologies provide the same measurement results as a conventional contact profiler—but in a fraction of time.
