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.
