High-Accuracy Roundness and Surface Texture Measurements

World's highest rotation accuracy of 0.02+3.2H/10000 μm
contributes to production of highly accurate parts.


Playing dual roles: Replacing a detector allows measuring surface texture and roundness

Typical machine arrangement is to equip a roundness measuring instrument to evaluate the roundness and a surface texture measuring instrument to evaluate the roughness. Respective instruments conduct functions from alignment through measurement/ analysis specialized in each instrument purpose. RONDCOM NEX Rs plays a role of both measurements of roundness and roughness, and the distinction contributes to the extreme reduction of installation space and cost, and the maximization of working efficiency.

Roughness Measurement for Workpieces with Axial or Rotary Shape

The platform of a roundness measuring instrument basis allows utilizing the automatic centering function for the roundness measurement, and the function saves time for positioning the ridgeline for roughness measurement in axes.
Furthermore, the full automatic measurement feature supported by CNC specification enables the consecutive roughness measurements on circumference, on edge face, and so on.
The instrument functions as a common roughness measuring instrument by placing a workpiece on the tilt cross table, R-axis playing a role of X-axis in a roughness measuring instrument.

High-Accuracy Roughness Measurement (Conformity to JIS/ ISO)

Achieves high accuracy roughness measurement in Z-axis, R-axis and T-axis. Since measurement can be performed at a speed reduced to almost the same level as commonly used surface texture measuring instruments, bouncing of the stylus is suppressed so that measurement results with less noise can be obtained.

Lead-Twist Measurement (Option)

Measure the periodic and fine twist structure on a cylindrical shaft. Visualization of twist structure enables easy analysis.
