Mid-May 2009 – Having explored the possibilities of ultrasonic water deburring, the company is also resuming orders for solvent-based ultrasonic deburring systems, to meet the expectations of some customers.
Main target solvents [HFC-365mfc ABZOL ABZOL etc.].
During the CFC-113 era, the author developed a non-vacuum degassing ultrasonic cleaning device using a double interface system, received a special examination from the Patent Office and received a government subsidy, and developed the world’s first automatic degassing ultrasonic cleaning machine (ultrasonic cleaner with cavitation enhancement system S-8000).At that time, the purpose was not deburring but powerful cleaning.Solvents generally dissolve a large amount of air, and it was clear that ultrasonic cavities can only be generated by ultrasonic waves in the first few seconds of ultrasonic oscillation – in other words, ultrasonic cleaning was only possible at that moment.
The CFC-113 (Freon 113) powerful ultrasonic cleaner was created as a countermeasure.Its catchphrase is: If other companies use an eight-tank CFC cleaner, we guarantee its capacity with a single tank!If other companies take 30 minutes, we guarantee to clean in 30 seconds!This was a tremendous sales copy, even thinking about it now!It was sales copy.But that was just before the demise of the CFC-113 due to ozone depletion issues, and after selling a few dozen units, we were forced to stop selling them, and I have since had no choice but to focus on water.Solvent-based cavitation enhancement systems offer tremendous ultrasonic performance, but therefore have various limitations that make them different from conventional cleaners.I have given up on this technology when I realised that it would disappear with me and be forgotten.
Water is a wonderful liquid.It is the water of life, the best cleaning agent and a liquid with many mysterious and unknown possibilities.So what is different from the point of view of ultrasonic cavity applications?It is surface tension and specific gravity (density).The source of the impact force of the cavities generated by ultrasound is essentially the high-speed movement of mass, so compared to water, [heavy] solvents can be likened to the difference between the punches of a lightweight boxer and a heavyweight boxer.The fast movement of heavy objects is also highly destructive.Furthermore, the surface tension is small.The resistance to movement is small.There are many other differences between water and solvents, such as the non-use of vacuum deaeration (cannot be used – evaporation occurs), but these will be omitted here as they touch on design know-how.If the cost of the solvent is not considered, or if evaporation measures have been sufficiently taken, and the object to be deburred has high added value and has limitations for ultrasonic deburring with water, ultrasonic deburring with a solvent has sufficient potential as a precision deburring method that exceeds the limitations of water for the above reasons.The author has conducted more than 3,000 ultrasonic water deburring experiments and has delivered many systems.We recommend the ultrasonic deburring of solvents to those customers who have high expectations for the next step in the process.
