Frequently Asked Questions About Vibratory Polishing Machine

Today, Xiaobian will talk about the common problems about the Vibratory Polishing Machine .The bigger problem is “over-polishing”. When the equipment is used for a long time, the surface quality of the mold will be worse, then “orange peel” and “pitting” will occur. How should we solve it? ?When the workpiece appears “orange peel” phenomenon, it is caused by overheating of the mold surface or excessive carburization. When the polishing pressure is relatively large, the polishing time is longer, which will lead to the phenomenon of “orange peel” and what is “orange peel”. “What?” That is, the surface is irregular and rough; the relatively hard steel can withstand the polishing pressure is relatively large, for the softer steel is very prone to over-polishing phenomenon.So how do you eliminate the “orange peel” of the workpiece? First, the defective surface needs to be removed, and then the grinding particle size is slightly thicker than the previously used sand number, and the tempering temperature is lowered by 25 ° C, followed by the elimination of the stress until satisfactory results are obtained. There is also a phenomenon of “pitting” on the surface of the workpiece. When the polishing pressure is relatively large, the polishing time is long, the purity of the steel is insufficient, the content of hard impurities is high, and the surface of the mold is rusted.   information about vibratory polishing machine: https://www.zhongyun-machine.com/product/vibratory-polishing-machine/
