JMZ-TK Series
JMZ-TK Vibration Isolator: Press the "Silence Button" for Your Precision Equipment
Vibration and impact are invisible "killers" of precision equipment. They permeate everywhere — micro-vibrations from the ground, the operation of the equipment itself, and even vehicles passing by in the distance can all become culprits affecting equipment performance. Xi'an Hoan Microwave Co., Ltd. deeply understands this, and the design concept of its JMZ-TK series friction damping vibration isolators is like pressing an efficient "silence button" for precision equipment, filtering out all harmful disturbances.
The "silencing" secret of JMZ-TK lies in its extraordinary ability to "dissipate" vibration energy. Unlike viscous damping that relies on material internal friction, friction damping is a more direct and efficient way of energy conversion. The carefully designed friction pairs inside JMZ-TK, through continuous and controllable sliding friction at the microscopic level, irreversibly convert mechanical energy into thermal energy. This process responds extremely quickly with no delay, allowing the vibration isolation system to "react instantly" and suppress vibrations at the very beginning of their occurrence.
What is particularly worth mentioning is its outstanding performance in low-frequency vibration and micro-vibration control. Many precision measurement and processing processes are extremely sensitive to low-frequency disturbances in the range of 5Hz to 100Hz. Traditional vibration isolation solutions often fall short in this frequency band. Through precisely adjusted friction damping force, the JMZ-TK series can effectively increase the system's equivalent damping ratio, significantly suppress resonance peaks, and quickly attenuate low-frequency vibrations. This means that equipment installed on JMZ-TK vibration isolators can operate on a nearly "stationary" reference plane — whether it is the optical path of a laser interferometer or the probe of an electron microscope, both can obtain an unprecedentedly stable environment.
For laboratories, metrology centers, astronomical observatories, and high-end manufacturing industries, JMZ-TK provides not just a vibration isolation product, but a fundamental guarantee for improving the accuracy of core data and process precision. Choosing JMZ-TK from Xi'an Hoan means choosing to create a pure, disturbance-free operating environment for your critical equipment.
