Precision and durability in the high-temperature range
We would like to present you with a success story that revolves around the challenges and innovations in the production of piezoelectric sensors. These sensors are predestined for the precise measurement of pressure, force, torque and acceleration in highly dynamic and quasi-static applications. Their housings are made of high-temperature steels, which are chemically resistant up to over 400 °C. However, the unique material properties presented challenging tasks in the machining process.
Challenges: Manual adjustments to the cutting edge and lack of chip control
In the past, numerous internal turning tool cutting edges were manually adapted to the specific bore shapes. This resulted in a great deal of time being spent on set-up, as the reproducibility of the cutting edge geometry was not guaranteed. Several iterations were necessary when changing tools in order to produce the required holes in the sensor components with tolerances of hundredths of a millimeter. In addition, insufficient chip control led to damage to the bore surface.
Innovative solutions through collaboration with Kistler
In close cooperation with Kistler, we have developed and continuously optimized new, application-specific Swiss-MicroTurn cutting geometries. This joint effort has led to a significant reduction in set-up times and consequently to an increase in productivity.
The joint effort is paying off: Easier and safer setup, consistent precision and increased performance
The set-up process is more efficient, which has led to a considerable reduction in machine downtimes. Process stability has improved significantly. Particularly pleasing is the consistent and predictable performance that is now achieved. Consistent chip removal has also significantly improved the surface quality of the finished sensor components.
Conclusion: Successful partnership and innovative results
This success story is an example of how close cooperation, innovative technologies and targeted optimization can lead to outstanding results. The improved quality and efficiency of the machining processes help to meet the demanding requirements in the manufacture of piezoelectric sensors in a cost-optimized manner.
