ULTRASONIC DEBURRING/CLEANING METHOD AND APPARATUS

摘要

To provide an ultrasonic deburring/cleaning technology that is especially effective for removing non-metal burrs integrated with metal, or for removing a non-metallic foreign matter or the like adhering to the metal.SOLUTION: In order to remove non-metal burrs integrated with metal, a workpiece W is housed in a conductive basket 14 and immersed in washing water in a washing tank 4, as well as setting a metal portion Wk of the workpiece W as a cathode and a basket 14 side as an anode, a direct current is applied, and degassing dissolved gas in the washing water to 2 mg/l or less, an ultrasonic wave is emitted to remove burrs on a non-metal portion Wp. It is also effective in removing a foreign matter and the like in the non-metal portion Wp adhering to the metal portion Wk.SELECTED DRAWING: Figure 1
