Q & A

What is the primary principle behind ultrasonic cleaning?

Ultrasonic cleaning uses high-frequency sound waves to generate vibrations that remove contaminants from surfaces without damaging the material.

How do ultrasonic machines work in terms of vibrations?

Ultrasonic machines produce high-frequency vibrations, typically ranging from 25 to 50 kHz, which are transferred to a workpiece through a transducer and sonotrode, causing the material to vibrate and release impurities.

What are the main types of ultrasonic machines mentioned in the transcript?

The main types of ultrasonic machines mentioned are stationary ultrasonic machines, rotary ultrasonic machines, and combined vibrating tools for specialized tasks like drilling and profiling.

What are some advantages of using ultrasonic technology?

Advantages of ultrasonic technology include no heat production during the process, preserving the material's physical properties, and effective cleaning of delicate or hard-to-clean materials.

What are some of the disadvantages of ultrasonic machines?

Disadvantages include slower metal removal rates compared to traditional methods, higher operational costs, and the need for specialized skills to operate the equipment.

Why is ultrasonic cleaning particularly useful for delicate materials?

Ultrasonic cleaning is ideal for delicate materials because it removes contaminants without causing damage or heat buildup, which could affect the material's properties.

What materials are ultrasonic machines commonly used to process?

Ultrasonic machines are commonly used for materials such as tronic boards, metals, plastics, and other difficult-to-process materials like ceramics and fine fibers.

How does the vibration frequency in ultrasonic machines affect the cleaning or processing results?
