Portable Measuring (Articulated Arms)

WD Hearn offers a range of Portable Measuring systems including the Nikon MMDx scanning head, MCAx Articualated measuring arm, and K-series Optical CMM. In basic terms these are accurate measuring systems that are used and manouvered by hand, and are easily transported by a single operator.

McAX Arm range

The MCAx Manual Coordinate measuring Arm is a precise, reliable and easy-to-use portable 7-axis measuring arm. It is the perfect partner for the ModelMaker MMDx/MMCx digital handheld laser scanners and Focus Handheld scanning and inspection software. This total solution’s accuracy, capability and portability make it feel perfectly at home in the metrology lab, on the shop floor and in-the-field.

The MCAx arm can be equipped with a wide range of probing systems for laser scanning, touch-trigger measurements and continuous scanning. Its flexibility makes this measurement arm the perfect solution for the widest range of measurement tasks. The new 7-axis MCAx range of articulated arms is available with a measurement volume ranging from 2.0 and 4.5 meter diameter.

Key benefits:

  • High accuracy and fast data throughput saves time and money
  • Optimized for hard-to-scan surfaces
  • Designed for use under all shop floor or field conditions
  • Extreme temperature stability and zero warm-up time
  • Quick and easy plug-and-play setup
  • Short learning curve
  • On-board calibration storage
  • Scanner compatible with all major brands of portable localizers and point cloud software
  • No external controller
  • Automatic probe recognition
  • Enhanced ergonomics mean stress-free usage
  • Seamless transition between scanning and touch-probing

ModelMaker MMDx Scanning Head

The ModelMaker MMDx handheld laser scanners are ideally suited for portable 3D inspection and reverse engineering applications. Its camera technology is a major leap forward in 3D laser scanning, as it introduces a high frame rate and a large stripe width up to 200mm for ultra-productive scanning. MMDx incorporates Enhanced Sensor Performance (ESP3) to scan all sample materials and surface finishes in a single move.

Key benefits:

  • Faster and more accurate scanning saves money and time
  • Ergonomic, light and small scanner
  • Scans almost all industrial materials
  • Portable out-of-the box system
  • Easy and fast plug & play set-up
  • Designed for use in all shop floor conditions
  • Optimized for hard-to-scan surfaces

K-series: Optical CMM

The portable K-Series Optical CMM system forms the core of different metrology solutions. As it faces no mechanical constraints , users can freely walk around and measure points or scan surfaces as desired. The metrology area activated by the Optical CMM fits an entire vehicle and can be easily expanded. The Optical CMM is also suitable for measuring dynamic motion and researching transient events. Its third use relates to industrial robots. By tracking robot movement in real time, Optical CMM technology drives increased positional accuracy for robotized inspection and manufacturing tasks.

Key benefits:

  • Portable and mobile configuration offering easy setup and ergonomic operation
  • Full freedom measurements with walk-around SpaceProbe and K-Scan
  • Suited for lab, shop and field measurements
  • Large (17m3) and expandable measurement volume
  • Measurement object motion compensation through dynamic object referencing
