RONDCOM NEX RS 200/300

High precision CNC roundness and roughness measuring instrument with fully automatic workpiece alignment


Modular system with numerous product variants

Highly accurate roughness measurement as per DIN EN ISO

Measurement range up to 360 mm diameter

Rotation precision: (0.02+3.2H/10,000) µm

Z-axis precision: 0.10 µm/100 mm
  • Fully automatic alignment of the workpiece and CNC programming of the measurement procedure
  • Roughness measurements in the R and Z axis as well as the gyration rotation axis
  • Twist measurement with Surfcom MAP 3D profile assessment (optional)
  • Offset probe sensor holder (patented) makes measurement below the R-axis possible
  • CNC rotation and swing head (optional = Rondcom nex 300)
  • Extremely quiet air bearings that are specially developed for high precision roughness measurements, in the rotation direction too
  • Ceramic R-axis – reduced weight and thermally stable
  • Additional linear scale in the R-axis and Z-axis and rotation axis
  • Different variants: Z = 300 mm or 500 mm, for RONDCOM NEX α with 900 mm
  • Workpieces up to max. 30 kg, for RONDCOM NEX RS α up to 60 kg
  • DX version with active anti-vibration table and system enclosure (optional)
  • XY positioning table for large quantities (optional)
  • Potentiometer ensures reliability for CNC measuring processes

Area of application
The RONDCOM NEX RS offer the possibility of conducting high precision measurements of the form and surface parameters at the same time, in accordance with ISO standards. Measurement precision can be measured in a way which was only possible with special roughness systems until now, thanks to the special air bearing concept. The RONDCOM NEX RS is able to not only measure the position, form and roughness in the R and Z direction, but also in the rotary axis. It therefore has no competitors and is unique on the market.
