Hommel-Etamic Roundscan

Highly efficient solution for combined form and roughness measurements

System Highlights

  • Highly accurate air bearing rotary table with impressive rigidity for consistently high precision
  • Vertical measuring axis available in three different heights, depending on requirements
  • Basic version for form measurement with 1 μm resolution of the R/Z axis and 20,000 points in the C axis
  • High Resolution version (HR) for combined form and roughness measurements with 0.1 μm resolution in the R/Z axis and 720,000 points in the C axis, as well as integrated linear scale and air damping with active level control

Your benefits:

  • Saving of time: very fast, fully automatic centering and leveling and CNC controlled measuring axes for save measuring, even on complex workpieces
  • Flexibility: combined form, roughness and twist measurements in a single clamping operation with no probe arm changes; small parts such as valves can be measured with a small measuring circle
  • Ergonomics: optimised design for convenient standing or sitting operation of the measuring system

Fully automatic measurements with innovative probe system for efficient measurement of form, roughness and twist

  • CNC controlled tilt and rotation module MDS3 for measurements at any position on the workpiece
  • Double-tipped probing system for measurements with two different probe tips for form and roughness
  • Adjustable and switchable probe force for measurements in accordance with standards
  • Probing system can be switched from form to roughness during the CNC run
  • High resolution of the axes for a minimal measuring point distance for roughness measurements
  • Low measurement speed from 0.2 mm/s can be run
  • Only very low basic interference of the measuring axes, even at maximum resolution
  • Form and roughness measurements can be programmed fully automatically; no retooling times for fast and reproducible measurements
  • Magnetic probe arm coupling for fast changing of the probe arm and protection in case of collisions

Ergonomic measuring station

  • Height-adjustable, tiltable evaluation unit
  • Convenient standing and sitting workstation
  • Lockable cabinets for safe storage of evaluation computer and printer
  • Control panel for performing key operations while maintaining a view of the workpiece and probe
  • Integrated probe arm rest
