RONDCOM NEX Series

Features
RONDCOM NEX and RONDCOM NEX Rs are universal form tester for the analysis of roundness, roughness, cylinder form, perpendicularity, parallelism, straightness, flatness, coaxiality, concentricity, and thickness error. With rotational error of just 20 nanometers, both form testers are ideal for a wide range of precision parts that have a height of 300 mm or 500 mm and weigh up to 60 kg.

Perfect positioning

The patented CNC offset stylus mount enables CNC-guided rotating and pivoting of the stylus and allows deep insertion and also measurement below the R axis.

More accurate measurements

The form testers of the RONDCOM NEX Series additionally feature an on-board R axis ceramic with high rigidity and reduced weight, allowing even more accurate measurement of large cone angles, diameters and straightness.

Improved design

The form testers have an extended centering range of ± 5 mm and a precise, wear-free rotary table on air bearings. Thanks to the improved design, the form tester is even more stable against air circulation.

RONDCOM NEX evaluates form and position tolerances such as roundness, cylinder form, perpendicularity, parallelism, straightness, flatness, coaxiality, concentricity, thickness error and radial runout.

All advantages at a glance

  • Highest accuracy in its class with a broad spectrum of applications
  • Linear scale for exact measurements in the R axis direction
  • More accurate measurement via a CNC pivot around the measuring sphere
  • Large deflection range and high resolution of the detector and stylus system for higher throughput

Options

The accurate form tester series RONDCOM NEX are also vailable as a sturdy, space-saving and attractively-priced FX version with integrated, active vibration damping, as comprehensive SD desk furniture or as a DX version suitable for production. More options are listet below. 

Precision, rotary table on air bearings and CNC offset stylus mount are the outstanding features of RONDCOM NEX.

RONDCOM NEX

  • Available as RONDCOM NEX 100 (manual machine), the RONDCOM NEX 200 (automatic part alignment) and the RONDCOM NEX 300 (full CNC)
  • Higher throughput through fast, fully automatic alignment for RONDCOM NEX 300
The RONDCOM NEX Rs form tester enables the precise measurement of roundness and roughness in the R, T and Z axes and features best-in-class rotational accuracy.

RONDCOM NEX Rs

  • Flatness measurement and measurement of the external diameter possible
  • Optional measurement of shaft structures and optional twist measurement
