[外文]This hydrofinish technology presently is only applicable for the mold cavities with through holes and exterior grooves on small components. The workpiece to be processed shall not be too large. E.g., The scope of workpiece to be processed with the hydrofinish machine of PUNCH Industry Dalian isφ80×H260, i.e., the excircle of cavity to be polished shall not exceedφ80 and the height shall not exceed 260mm.
In spite of the restriction on the applications of hydrofinish technology, it has contributed much to the improvement of polishing technology. Compared to traditional polishing technology, the most significant benefit of hydrofinish technology is to greatly improve the polishing efficiency and effects of shape products and products with a deep hole, resulting in the high interchangeability of large amount of products to be polished. In a word, the hydrofinish technology , as one of the high performance polishing means, will find extensive applications.
