Disk Inspection & Measurement System Digital Optical Comparators

Overview Technical Data Get a Quote

The VisionGauge® Disk Inspection & Measurement System is the ideal solution for the inspection & measurement of slots in turbine disks, both large & small.

Automatically carry out 100% inspection, to very high-accuracy, and collect operator-independent results, directly on the shop floor.

The VisionGauge® Digital Optical Comparator 5-Axis Inspection and Measurement Systems are a very cost-effective, perfectly adapted solution for checking EDM and LASER-drilled drilled holes and slots. It is rapidly becoming the new standard in the industry!

Features & Benefits

  • Fully-automated operation.
  • No operator-to-operator variation
  • Quickly, easily and accurately inspect 100% of a disk’s slots
  • Easy to program (can use your CAD data directly!)
  • Fast, accurate & easy-to-use
  • Extensive set of measurement tools
  • Straightforward operator interface: barcode-reader and joystick
  • Intuitive software
  • Patented & patent pending technology
  • Powerful & innovative software tools
  • Sharp, clear & ultra-high resolution image!

  • Extended optical depth of field and extended working distance for maximum flexibility!
  • Automatically create reports and collect measurements, statistics, images and other data for complete documentation
  • Automatic image & data collection with built-in SPC and data-exchange capabilities
  • Fast and intuitive “operator review” mode to quickly revisit out-of-tolerance areas
  • High-precision movements on all axes
  • All axes are encoded
  • Extended travels available to accommodate large disks
  • High load capacity (for large & heavy disks)
  • Robust shop-floor design

High-resolution optical system
20X equivalent optical magnification (approx.) Working distance = 9.0” (228 mm) Depth-of-field = 1.8” (45mm) Field of view = 2.0” (51mm) x 1.2” (32mm) = 2.4” (60mm) Ø Optical system accuracy: better than +/- 0.00015” (4 μm)
LED illumination
Ultra-bright, all-LED based (for stable and repeatable illumination conditions & results as well as long life) Fully computer-controlled & programmable Produces very high brightness to easily handle even difficult-to-image areas The system’s dual-source illumination module provides lighting at different angles of incidence (i.e. both near-vertical and low-oblique) for wide applicability across a very broad range of part geometries.
VisionGauge® Software
Powerful and easy-to-use Intuitive, windows-based graphical user interface (i.e. “point & click”) Full 5-axis transforms Advanced software corrections with full 3D mapping across the system’s entire work envelope Includes a wide range of powerful inspection and measurement tools Robust & field-proven, with a broad installed base (over 3500 license in use worldwide)
5-axis corrections
Chuck offset, fixture height and fixture center-of-rotation (X,Y) offset
Software feature-detection tools
Extremely powerful “adaptive” software feature-detection tools are able to accurately find and locate features of interest (such as EDM-drilled holes) on different surfaces, with different reflectivity, at different viewing angles, etc.
