Maximizes the effect of high-speed, microscopic
ultrasonic vibrations in “cutting.”
Ultrasonic cutter

SF-3400II(Oscillator) SF-3140(Transducer)

Highly versatile combination suitable for large-scale hand-held cutting.
High-output cutter for manual operation: Assisting manual operations with clear cutting
This is a high-power ultrasonic cutter featuring the ultrasonic power output of 220 W. The tool’s ultrasonic vibrations at a frequency of 22 kHz (22,000 vibrations per second) drastically reduce the cutting resistance. Varieties of materials can be cut even more rapidly and cleanly with a lower processing pressure. A function to enable constant monitoring of loads during cutting was added anew, thereby ensuring added safety and user friendliness.
  • The output adjustment can be done in step-less and continuous manner from the minimum to the maximum levels.
  • The constant amplitude circuit always keeps vibrations at stable amplitude.
  • The overload protection circuit is featured.
  • Force air cooling is possible by installing the air inlet (SF-3140).
