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.将要清洁的物体直接放在超声振动体的表面上。否则会在工件表面造成轻微划痕。应采用合理的清洁方法，例如清洁吊篮。工件放置在多孔托盘或网篮中。

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.超声功率密度过大。它会损坏某些珍贵而的物品的表面，例如石英，蛋白石，珍珠，玉，孔雀石，祖母绿和珊瑚。清洁此类物品时一定要小心，因为可以使用具有连续可调超声波功率的超声波清洗设备。

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.选择化学腐蚀被清洁物体的清洁液。因为可以通过超声波增强清洁剂对待清洗工件的潜在负面影响。仔细选择正规的超声波清洗机。

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.
