众所周知，超声波清洗机的应用范围很广，但对于非专业人士来说，如何选择适合自己的超声波清洗机是一个棘手的问题。 针对这一情况，现简要介绍如下：
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较差，则选择低频超声波清洗机比较合适，如20kHz、28kHz; 如果需要清洗的工件的表面加工精度比较高，则选择中高频超声波清洗机比较合适，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无孔或孔径大，可以选择低频超声波清洗机，如果工件表面孔径小，深度较深，则需要选择高频超声波清洗机。
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较高，最好同时使用低频和高频超声波清洗机。
3. if high precision is required for workpiece cleaning, it is best to use low-frequency and high-frequency ultrasonic cleaning machines together.
