Recently, I received a customer product - precision nut parts, requiring removal of the cross-hole burr problem in the inner hole. Burrs can be seen everywhere with the naked eye. When viewed under a microscope, the size of the burr is larger than expected. If it is not removed, it will seriously affect the accuracy and overall quality of the product. This is more troublesome.

In the face of this cross-hole deburring problem, if the traditional deburring method is used, it is inefficient or difficult to deal with complex internal burr problems.

Through Hsihwa polishing technology, we understand the use of abrasive flow polishing technology for processing. Abrasive flow technology is equivalent to a precise internal cleaning of parts. The core of abrasive flow is to use polymer elastic abrasive to reciprocate grinding through the inner hole or workpiece surface at a constant speed through extrusion movement to achieve better polishing and deburring effect without damaging the workpiece itself.

After a professional and efficient polishing process, the nut was observed again, and the inner holes and edge burrs were completely removed. The surface was smooth and flat, and the product achieved its original accuracy and finish.

It has to be said that abrasive flow polishing technology is indeed a magical polishing technology, which can not only solve the problem of deburring complex workpieces well, but also has multiple advantages such as high efficiency, precision, environmental protection and safety. If you also have such products that need mirror polishing, welcome to Hsihwa Company for trial throwing!
