Product Information


ZEISS RONDCOM 65 B Excellent rotational accuracy, ultra-precision, high throughput and long-term stability.
Fast automated alignment and a rotary table on air bearings impress with their precision and efficiency.

A rotational accuracy of 10 nanometers makes the trend-setting RONDCOM 65 B form tester the best in its class. The system positions workpieces fully automatically in less than a minute. The R, Z and rotary axes of the RONDCOM 65 B are equipped with ultra-precise air bearings, enabling the outstanding measurement of the smallest tolerances. Using granite for the base, columns and the R axis makes the machine durable and stable. The RONDCOM 65 B features an incremental glass scale in the R axial direction, and the thermal and vibration insulated table ensures excellent measuring stability. The optional patented CNC offset stylus mount of the RONDCOM 65 B measures difficult-to-reach components, even below the R axis, and enables deep insertion with the standard stylus.
