ZeroTouch non-contact metrology platform

A high-speed, precision inspection machine for 100% near-line or inline gear inspections.

Non-contact 3D Gear Inspection System

ZeroTouch® ZTG-2580 is a non-contact gear inspection system that generates a 3D point cloud, providing manufacturers with real-time metrology and inspection data to optimize production processes and improve ROI.

A New Way to Inspect Gears

Using multiple laser triangulation sensors that acquire millions of data points per sensor, the ZeroTouch® ZTG-2580 gear inspection system performs 3D inspections of complex gear geometries and surface defects with speed, accuracy, and flexibility.


Accuracy and repeatability

ZTG-2580 achieves reliable and repeatable measurement by 3D referencing over the complete reference surfaces. Collecting millions of data points minimizes surface local defects or roughness, making the machine extremely repeatable even when measuring recently milled or cut gears.


Automatic part loading and unloading

Simple interfacing with the manufacturing process through a loading and unloading robot integrated in the ZTG-2580 gear inspection system.

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.
