1. Cracks or breaks
Reasons:
Material fatigue caused by long-term high-frequency vibration.
The tool head is subjected to excessive impact force when in contact with the workpiece.
Improper installation or resonance frequency offset causes abnormal vibration.
Performance:
Cracks appear on the surface of the tool head, and in severe cases, it breaks directly.
The ultrasonic output power decreases, and the cleaning or processing effect becomes worse.
2. Loosening or falling off
Reasons:
The threaded connection is not tightened or loosened due to long-term vibration.
The fixing glue ages and fails (such as epoxy resin debonding).
Performance:
Abnormal noise is generated between the tool head and the transducer.
Ultrasonic energy cannot be effectively transmitted, and the no-load current of the equipment is abnormal.
3. Corrosion or wear
Reasons:
The tool head material is incompatible with the cleaning fluid or processing medium (such as a stainless steel tool head in contact with a strong acid).
Long-term friction causes surface wear.
Performance:
Pitting, pits or scratches appear on the surface of the tool head.
Ultrasonic energy loss increases, and the cleaning or processing effect decreases.
