眾所周知，超聲波清洗機的應用範圍很廣，但對於非專業人士來說，如何選擇適合自己的超聲波清洗機是乙個棘手的問題。 針對這一情況，現簡要介紹如下：
as is well known, ultrasonic cleaning machines h**e a wide range of applications, but for non professionals, how to choose a suitable ultrasonic cleaning machine is a challenging problem. in response to this situation, the editor will provide a brief introduction as follows:
1、如果需要清洗的工件表面加工精度較差，則選擇低頻超聲波清洗機比較合適，如20kHz、28kHz; 如果需要清洗的工件的表面加工精度比較高，則選擇中高頻超聲波清洗機比較合適，如40kHz、60kHz等。
1. if the surface machining accuracy of the workpiece that needs to be cleaned is relatively rough, a low-frequency ultrasonic cleaning machine can be chosen, such as 20khz, 28khz, which is more suitable; if the surface processing accuracy of the workpiece that needs to be cleaned is relatively high, a medium to high frequency ultrasonic cleaning machine can be selected, such as 40khz, 60khz, etc., which is more suitable.
2、需要清洗的工件表面基本無孔或孔徑大，可以選擇低頻超聲波清洗機，如果工件表面孔徑小，深度較深，則需要選擇高頻超聲波清洗機。
2. if the surface of the workpiece that needs to be cleaned has basically no holes or a larger aperture, a low-frequency ultrasonic cleaning machine can be selected. if the surface aperture of the workpiece is smaller and deeper, a high-frequency ultrasonic cleaning machine needs to be selected.
3、如果工件清洗精度比較高，最好同時使用低頻和高頻超聲波清洗機。
3. if high precision is required for workpiece cleaning, it is best to use low-frequency and high-frequency ultrasonic cleaning machines together.
