VACUUM ELECTROLYTIC ULTRASONIC CLEANING METHOD AND VACUUM ELECTROLYTIC ULTRASONIC CLEANER

摘要

To provide a cleaning method using an electrolytic cleaning liquid which can surely clean the inside of a small-diameter stop hole which is formed at a matter to be cleaned such as a molding metal mold, a fine clearance or the like, and a cleaner.SOLUTION: In a vacuum electrolytic ultrasonic cleaner 1, an ultrasonic vibrator is driven by repeating a vacuuming process for vacuuming the inside of a cleaning tank 8 so as to be brought into a prescribed vacuum state by bringing the cleaning tank 8 in which an electrolytic cleaning liquid 15 is stored into a sealed state, and a repressurization process for returning the vacuum state to atmospheric pressure after releasing the vacuum state, makes a DC current flow between the electrolytic cleaning liquid and a matter to be cleaned, and applies vacuum electrolytic ultrasonic cleaning to the matter to be cleaned which is immersed in the electrolytic cleaning liquid 15.SELECTED DRAWING: Figure 3
