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 E_0,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
