Excellent Rotational Accuracy
RONDCOM 65 B

The trend-setter among form testers
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.
RONDCOM 65 B
FeaturesIdeal solution for various applications
With a rotational error of just 10 nanometers, RONDCOM 65 B is ideal for a wide range of precision parts with a maximum diameter of 420 mm and weighing up to 60 kg.
Overcome challenging measurements
The optional patented CNC offset stylus mount of RONDCOM 65 B measures difficult-to-reach components, even below the R axis, and enables deep insertion with the standard stylus.
Excellent measuring stability
The R, Z and rotary axes of 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.

All advantages at a glance
- Universal form tester with an excellent rotational accuracy of 10 nanometers
- Higher throughput thanks to automatic alignment in less than one minute
- Large deflection range of ± 1,000 µm and a high-resolution IMR sensor of 2 nanometers
- IMR sensor with safety function in all orientations for maximum protection of the stylus
- Incremental glass scale for highly accurate measurements in the R axial direction
