LEGEX Coordinate Measuring Machine

June 01, 2015

Mitutoyo America Corp. announces the release of the latest LEGEX ultrahigh accuracy CNC coordinate measuring machine. The ultra-accurate LEGEX 4 surpasses conventional CMM performance to deliver world-leading accuracy in length measurement of E0,MPE = (0.28+L/1000) μm.

With the unceasing advancement of scientific and industrial technologies and driving demand for significant improvements in high-accuracy manufacturing, Mitutoyo LEGEX meets the needs of a growing number of manufacturers with applications such as ultra-precise molds, components and aspherical lenses in the automotive, aviation and medical instrument industries, and calibration of master gages for research institutes. To meet these increasing needs, Mitutoyo took a fresh approach when it came to accuracy, starting from the elemental technology level and working upward, with the aim of eliminating all possible sources of measurement error.

Key features:

• Sources of static and dynamic error minimized to realize world-leading measurement accuracy of 0.28 μm

• Fixed-bridge structure with moving table

• Base is made from spheroidal graphite (ductile) cast iron in a sealed-structure design to provide high rigidity and vibration-attenuating characteristics

• High-rigidity structure and feed mechanisms increase accuracy and improve cycle times

• Thermally symmetric structure features full covers around the main body to reduce possible impact in ambient temperature changes

• Vibration-damping unit is standard

• An air server stabilizes the air temperature to 20°C ±0.1°C

  • calibration


    Checking measuring instruments and devices against a master set to ensure that, over time, they have remained dimensionally stable and nominally accurate.

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • feed


    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
