Roughness and Contour Metrology

With our measuring instruments, you can measure the roughness and contours of your components in a single probe step or in separate measurement runs.

Measuring Instruments for Measuring Contours and Roughness

HOMMEL ETAMIC measuring instruments can be used to measure either the roughness or contours of your workpieces. We offer versions that work in separate measurement runs and models that measure in a single probe step. You can also choose between mobile and stationary systems for simple and complex measuring tasks.

Advantages of Our Measuring Instruments

All of our measuring systems are highly precise and offer repetitive accuracy. They can detect even the smallest deviations from the standard, ensuring that you produce components with consistently high quality. The measurement run is largely automated, which prevents operator errors. You also save time, money and resources.

The instruments have a modular design, which means they can easily be integrated into existing measuring systems, or can be expanded. You can configure the measuring station according to your requirements. If required, we can develop and manufacture measuring instruments for contour and roughness measurement that precisely meet your requirements. You will also benefit from our years of experience and our comprehensive expertise.

Flexible Mobile surface roughness measurement

Waveline W800

Waveline W800 and W900 — for reliable results in the minimum amount of time

The new generation of Waveline W800 and W900 were designed to meet a variety of customer requirements for flexible, precise and fast measuring processes. All measuring station configurations are modular and can easily be expanded at a later stage.

An axis speed that is more than six times faster and an improvement in the ambient noise of approximately 30 percent demonstrate the significant performance improvement in comparison to the existing models. In addition, all measuring station configurations are modular and can easily be expanded at a later stage. The new W800 and W900 model series offers a suitable probing system for every field of application. It is particularly suited to many different measuring tasks in the measuring room, as the models typically include manual or semi-automated measuring processes. An additional benefit is the ease with which the probing systems can be swapped via a new magnetic quick-change adapter. This lends a very high degree of flexibility to daily routine measurements.


  • High precision: Accurate repeat measurement results.
  • Versatile application: Can be used for roughness and contour measurement.
  • Automated measurement run: Probe arm rises and falls independently.
  • Flexible: Probe arms are easy to change.

Fields of Application

  • Bearing industries: Sleeve bearing, slider bearing, ball bearing.

Measuring Instruments for Combined Roughness and Contour Measurement

Roughness and contour measurement in a single process — the measuring instruments offer two different probing systems.

T8000 RC - For Contour and Roughness Measurement

HOMMEL ETAMIC measuring instruments allow you to measure the roughness and contours of your workpieces. You get two probing systems in one measuring system. These two probing systems can be used independently of one another, saving you both time and money.

The measurement run is largely automated. Using the latest RFID technology, some of our measuring instruments can even detect which probe arm is being used, and set the measuring conditions accordingly. The probe arms are attached magnetically, which means they can be changed quickly and safely. As such, you can easily adapt the measuring systems to each new measuring task, achieving repetitive accuracy and highly precise results.

The instruments have a modular design and can easily be extended. The systems are also robust. They work without any problems even in tough production environments, making them ideally suited for use in rough industrial environments.

Waveline Wavemove - measurement in one process

Waveline Wavemove: Fully Automated Measurement of Large Workpieces

The Wavemove measuring instrument allows you to simultaneously measure the contours and roughness of your cubic or wave-shaped workpieces.

Wavemove - Fully Automated Measurement of Large Workpieces

The Waveline Wavemove measuring systems allow individual, CNC-controlled, fully automated roughness and contour measurements to be performed directly at the production line. Up to eight independent CNC axes position the workpiece and measuring system at all required measurement positions, ensuring precise measurement of all necessary features— fully automated without any operator intervention.

Workpiece-specific fixing devices make it easier to load and unload workpieces. If required, the workpieces can be automatically identified and assigned to the quality data.

These measuring systems are particularly suitable for the measurement of crank shafts, cylinder heads and cylinder blocks. Thanks to the robust design and the optional safety equipment, the measuring systems can be operated in the production environment itself. Small quality control loops and fully automated measurement runs allow you to take the lead in quality management.


  • Efficient: Combined roughness and contour measurement
  • Fully automatic: Multi-axis CNC control ensures high level of automation
  • Robust: Measuring systems also suitable for tough production conditions
