The vibration cutting method is a processing technique that significantly reduces cutting resistance by intermittently cutting with the tool tip vibrating at ultrasonic frequencies. When the tool tip is vibrated in a circular or elliptical motion using the bending vibration mode and longitudinal vibration mode, the cutting resistance can be reduced to less than 1/5, and particularly the radial cutting force becomes almost zero, enabling ultra-precision cutting of STAVAX with a diamond tool. By using the ultrasonic elliptical vibration cutting device 'EL-50Σ', it becomes possible to achieve ultra-precision micro-machining of high-hardness molds that were previously considered impossible. 【Features】 ○ No complex electrical adjustments are necessary → Ultra-precision elliptical vibration cutting can be performed simply by turning on the power switch of the controller. ○ The oscillation frequency is increased to 41 kHz → The elliptical vibrator is miniaturized to fit in the palm of your hand. ○ The vibrator case has a high-rigidity structure → Installation on the tool holder is also easy.

We have developed a high-precision elliptical vibration control device suitable for ultra-precision and fine processing, capable of stabilizing the vibration trajectory with an amplitude of approximately 1-2 μm at a high frequency of 39.8 kHz (with a fluctuation of less than 10 nm). We confirmed that it can maintain stable circular vibration with an amplitude of 2.5×2.5 μm p-p for an extended period of three days, with minimal heat generation. We simplified the structure and increased rigidity, and additionally installed an air cooling system that allows cooling air to flow through the vibrator case and cutting edge, suppressing the overall temperature rise, resulting in a compact and lightweight case. This allows for the stable control of practical high-amplitude elliptical vibrations for extended periods with minimal manual adjustments, enabling the handling of elliptical vibration cutting with the same feel as conventional single vibration ultrasonic cutting devices. *For more details, please contact us.
