The preload piezo actuator integrates high-reliability piezoelectric stack inside, which can achieve nanometer resolution, displacement travel can reach 260μm, microsecond response time, and the outside is protected by a cylindrical stainless steel shell.
The higher internal mechanical preload force can be applied to high load and high dynamic applications. sThe output of 50,000N makes it very suitable for cavity tuning, active vibration, shock absorption or adaptive mechanics. At the same time, its small size and high resonance frequency make it very suitable for applications such as scanning microscopy, beam deflection, precision machining or microlithography.

Applications
Superconducting cavity tuning
By stretching the superconducting cavity in the axial direction by the resonator, the size of the acceleration gap is changed, and the frequency of the superconducting cavity is controlled. After coarse frequency adjustment by mechanical tuning, when the frequency of the superconducting cavity is close to the required frequency, the frequency is finely adjusted by the piezoelectric ceramic actuator. It uses the characteristics of large output and small displacement of piezoelectric ceramic actuators.
Micro EDM
A lot of debris will be generated in the process of machining micro holes using micro EDM, which will seriously affect the accuracy and processing speed of EDM. Piezoelectric actuators are used in the equipment, and the micro-nano-level displacement, high-frequency vibration, large output and other characteristics are used to effectively remove the debris generated by the process and play an excellent role in guiding the chips.
Shock absorption
Vibration is something that needs to be avoided or eliminated in many mechanical systems, such as the aerospace and automotive industries. When vibration is detected in the vibration monitoring system, by applying an electrical signal to the piezoelectric actuator, the piezoelectric actuator then generates a displacement opposite to the direction of the vibration, thereby counteracting the vibration.
