【Echo Tech】 Do ultrasonic cutter frequency involved in sharpness level?
“Ultrasonic level” could indicate in number, and it calls “frequency”, digit is “Hz”.
Hz is indicating that how many times did vibration happen in per second.
Ultrasonic cutter ZO series frequency is 40kHz(=40000Hz).
If we made up models increasing frequency, do you think that blades sharpness will grade up?
Mechanism of Ultrasonic cutter.
Why ultrasonic enhances a blade sharpness?
Imagine saw cutting tree. It has many fine blades on saw, and the secret is in each little spaces between blades. Each fine blades keep hit and release many times by moving saw, and it distance before blade hit to material makes impact and enhances sharpness. Saying more simply, it’s effective to giving impact on material by hitting many times(saw), than hit just once and pushing(knife).
When ultrasonic transmits to blade, it makes super speed vibration and it finely moves like hammer(hits material many times).
As our ultrasonic cutter is 40kHz, it cut with hitting blade 40,000 times per second.

What decides ultrasonic cutter sharpness.
We explained ultrasonic cutter’s mechanism in last column, and you may think high frequency makes more easier to cut materials.
..but that’s wrong.
Too much high frequency looses ultrasonic cutter sharpness.
Too much high frequency leads fine processing, but looses power, instead. Ultrasonic is delicate that needs fine adjustment for proper adjustment matches to unit.
Then, what certainly makes sharpness power up?
The answer is, output power.
By increasing output level, ultrasonic cutter’s transducer and blade works more powerfully.
However, each transducer installed in ultrasonic cutter has a proper output level. It means, supplying too much power leads transducer malfunction fast.
Be careful for cheap copy products.
We have seen some ultrasonic cutter brands sold from oversea companies, copying our ZO series. They were selling cheaper than our models, and specification were quite similar. We had seen some purchasers comments that it breaks soon.
Our ultrasonic cutter ZO series are very cheap models, realized by adopting custom components, and our original produce line. If you find more cheaper, similar models, you should be suspect whether it works correctly.
