Ultra-fine bubbles

By generating microbubbles (Ultra-fine bubbles) in a coolant, grindign efficiency is dramatically improved.

It solves the following problems:

  • Shortening tact time

  • Improving surface roughness; Reducing deviation of work pieces / Improving mirror finishing process and surface roughness

  • Extending grinding wheel life

  • Improving infeed of grinding

    Significant expansion of processing efficiency

    Bursted bubbles with high inner pressure (approx. 20 atm.) remove grinding chips of a grinding wheel by cavitation.
    This physical action makes grinding wheels sustainably sharp. As a result, you can increase a grinding depth of a work piece.



    Prevention of coolant corruption

    Many aerobic bacteria are generated as a result of increase of the volume of oxygen in a coolant. It prevents an outbreak of injurious bacteria.

    Improvement of dimensional accuracy

    Due to the low grinding contact angle and the high wettability, you can easily reach a processing point on a work piece. Moreover, you can also expect cooling effect by the heat of vaporization during the burst of Ultra-fine bubbles. These effects lead to reduction of a heat stress and a distortion, and improve dimensional accuracy.



    Life extension of grinding wheels

    Sustainable sharpness of grinding wheels show dicrease of abrasive grain separation. This results lesser dressing frequency and long grinding wheel life.
