During the use of electronic product screens, the glass surface may be scratched. Our self-developed and innovative polishing equipment uses 3D flat grinding equipment, which can more effectively ensure the flatness and clarity of the screen surface. In order to avoid the wear-resistant layer being completely thrown away after grinding and polishing, we use optical measuring instruments to measure the wear-resistant layer before and after grinding and polishing to ensure the quality of the processed product. Our innovative polishing process has effects, quality and stability far exceeding those of equipment on the market.
