High precision CNC roundness instrument with fully automatic workpiece alignment

Modular system with numerous product variants

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
  • Offset probe sensor holder (patented) makes measurement below the R-axis possible
  • Detector with automatic measurement force adjustment AFD (optional)
  • CNC rotation and swing head (optional = Rondcom nex 300)
  • Air bearing equipped high precision table-rotating instrument for wear-free run-out
  • Ceramic R-axis – reduced weight and thermally stable
  • Additional linear scale in the R-axis and Z-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 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 full automation of the RONDCOM NEX 200/300 makes use in the measurement room and user-independent operation in production and mass production possible. This minimises the influence of the operator, increases the measurement precision and is more time and cost effective in comparison with manual systems.
