Many hardware manufacturers will choose to purchase ultrasonic cleaning machines to clean parts. Some parts often have blind holes. These blind holes cannot be cleaned, which will affect efficiency. Therefore, ultrasonic cleaning machines are often used.

The blind hole is too small, and the water pressure cannot burst the bubbles blocked at the mouth of the blind hole. The transmission of the ultrasonic wave is based on water, that is, as long as the water can reach the ultrasonic wave, it will exist to achieve cleaning. However, a small amount of blind holes that do not penetrate into the cleaning agent cannot be cleaned.

The operation methods of the ultrasonic cleaning machine when the blind hole is clear are mainly as follows:

The first method: when designing the ultrasonic cleaning machine for hardware parts, a compressed air nozzle can be added in the tank. Connect to the factory's air source. When it is necessary to clean the parts with blind holes, slowly put in the workpiece and let the water flow into the holes as much as possible. After the parts are placed, compressed air is used to cause countless water columns to impact the workpiece. In order to make the air bubbles blocked in the orifice burst, the ultrasonic wave can better clean the blind hole parts.

The second method: use an ultrasonic cleaner combined with medium and high frequencies. The use of high-frequency ultrasonic waves is based on high-frequency oscillations, which breaks the air bubbles blocked in the blind hole. At the same time, combined with the medium-frequency blasting strong ultrasonic wave, plus appropriate degreasing and decontamination cleaning fluid, the stains and iron filings in the blind hole Swept away.
