±0.005MM METROLOGY

Zeiss CMM ±0.005mm Metrology & Quality Lab

Sub-Micron Coordinate Measuring Machines, Optical Comparators, and XRF Analysis.

You cannot manufacture what you cannot measure. JYH Prototype houses a world-class, temperature-stabilized metrology laboratory centered around high-precision Zeiss PRISMO 3D Coordinate Measuring Machines (CMM) with scanning resolution down to 0.9µm. We verify complex GD&T true positions, concentricity, and profile tolerances with automated tactile probing.
