Features & Benefits

    • 100% inspection of gear and teeth geometries with cycle times from 30 seconds per part
    • Installed in the immediate vicinity of the production line
    • Fast identification of production defects, enabling adjustment of upstream processes
    • 3D inspection of complex geometries using multiple sensors
    • Captures dense precision point cloud data with speed and accuracy
    • Advanced analytics integration with application-specific tools
    • Profile, helix, pitch, and runout measurements
    • Surface defect detection and characterization capabilities
    • Multiple laser line triangulation metrology sensors
    • Real-time data capture and storage for SPC analysis

Accuracy and Repeatability

ZeroTouch® 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

Configurable for manual and automatic part load and unload, ZeroTouch® can be installed in the immediate vicinity of the production line to improve production throughputs.

Upstream Process Improvements

Performing 100% inspection of gears and teeth geometries with measurement cycle times from 30 seconds per part, ZeroTouch® optimizes production processes by detecting and avoiding production deviation through real time measurements, allowing adjustment of upstream processes to reduce waste.
