Automatic ultrasonic cleaning machine is nondestructive to most parts. Although the ultrasonic cleaning machine produces thousands of micro explosions per second, the cleaning process is safe because the energy is at a small energy level. However, some exceptions may damage the workpiece to be cleaned. How to avoid the damage of the cleaning machine, this paper introduces a full-automatic ultrasonic cleaning machine. It cannot use chemical corrosive cleaners; You cannot place the cleaned object on the vibrating surface of the machine; Affected by high ultrasonic density.

1.將要清潔的物體直接放在超聲振動體的表面上。否則會在工件表面造成輕微劃痕。應采用合理的清潔方法，例如清潔吊籃。工件放置在多孔托盤或網籃中。

1. Place the object to be cleaned directly on the surface of the ultrasonic vibrator. Otherwise, slight scratches will be caused on the surface of the workpiece. Reasonable cleaning methods shall be used, such as cleaning the basket. The workpiece is placed in a perforated tray or basket.

2.超聲功率密度過大。它會損壞某些珍貴而的物品的表面，例如石英，蛋白石，珍珠，玉，孔雀石，祖母綠和珊瑚。清潔此類物品時一定要小心，因為可以使用具有連續可調超聲波功率的超聲波清洗設備。

2. The ultrasonic power density is too high. It will damage the surface of some precious and exquisite objects, such as quartz, opal, pearl, jade, malachite, emerald and coral. Care must be taken when cleaning such items, because ultrasonic cleaning equipment with continuously adjustable ultrasonic power can be used.

3.選擇化學腐蝕被清潔物體的清潔液。因為可以通過超聲波增強清潔劑對待清洗工件的潛在負面影響。仔細選擇正規的超聲波清洗機。

3. Select a cleaning solution that chemically corrodes the cleaned object. Because the potential negative effects of the cleaning agent on the cleaned workpiece can be enhanced by ultrasound. Carefully select the regular ultrasonic cleaning machine.
