In the daily polishing process, micropore deburring has always been a headache for us. When dealing with this kind of problem, we can only observe it through a microscope, and we can clearly see the rough surface of the fine burrs attached to the inner wall of the micropore. These seem inconspicuous, but they directly affect the accuracy and subsequent use effect of the part. If the treatment is not thorough, it is likely to cause the entire part to fail to be used normally, and even affect the subsequent assembly and product quality.

The customer has also considered the traditional manual polishing method. After all, the manual operation seems flexible and does not require complex equipment investment. But after actual attempts, it was found that the pore size of the micropore itself is very small, and it is difficult to manually penetrate into the interior of the inner hole, let alone accurately remove the inner wall burrs. Not only is the operation extremely difficult, but it also consumes a lot of manpower and time, and the polishing effect is uneven, especially the smaller inner holes, which cannot be solved. Sometimes not only do not remove the burrs, but also may cause scratches to the inner wall of the micropore, which is not worth the loss, so the traditional manual polishing is indeed not practical for the removal of burrs from the micropore.

The customer came to us for abrasive flow polishing and compared a variety of polishing equipment and processes. After repeated attempts and screening, they found that abrasive flow polishing is a more suitable way to solve the burrs in the micropores. The main reason for choosing this method is the high cost performance. Compared with some other high-end polishing equipment, the investment of abrasive flow polishing equipment is not high, and the operation is relatively simple, and it does not require too much professional manpower to maintain and operate.

When using abrasive flow polishing to treat microporous burrs, the abrasive can follow the shape of the micropores, penetrate into every corner of the inner hole, and polish the inner wall evenly, which can completely remove burrs without affecting the accuracy of the micropores. The entire polishing process is also relatively efficient, capable of batch processing parts, which greatly saves our time and labor costs, and well solves the problems we encountered before.

After each polishing is completed, we will observe the inside of the micropores through the microscope again. The burrs are removed, the inner walls of the micropores become smooth and flat, and our hearts are particularly at ease. Through this practice, we have deeply realized that when dealing with problems such as micropore deburring, we cannot stick to the traditional method. We must choose a polishing process and equipment with high cost performance and good effect based on actual needs.

In short, abrasive flow polishing not only helps us solve the pain point of microporous deburring, but also improves the processing quality and efficiency of parts. It also makes us understand that in production and processing, only by constantly trying and exploring and finding suitable methods can we better solve practical problems and improve production efficiency. In the future, we will continue to accumulate experience to make abrasive flow polishing play a better role and help production move forward smoothly.
