The Jiutu Auto Grinding Machine is specifically designed for second-hand phone refurbishment factories and recycling companies. It can process both straight and curved screens, supports infinite speed adjustment, and completes minor scratch removal in 3–6 minutes per phone. This makes it highly efficient for high-volume refurbishment operations compared to traditional manual methods.\u003c\/p\u003e\n\u003ch3\u003eQ2: What is the recommended polishing depth, and will it make the glass too thin?\u003c\/h3\u003e\n\u003cp\u003eA: The recommended polishing depth is less than 0.2mm per session. Only a very thin layer of glass is removed, which does not affect the structural integrity or daily use of the phone. After polishing, an oleophobic coating should be applied to restore the hydrophobic effect on the screen surface.\u003c\/p\u003e","brand":"JiuTu Machine","offers":[{"title":"Default Title","offer_id":42543200043252,"sku":"9TU-M079B","price":1558.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/7913\/3684\/files\/jiutu-machine-2-default-title-auto-grinding-machine-36779625578740.jpg?v=1776215326","url":"https:\/\/jiutustore.com\/it\/products\/auto-grinding-machine-for-second-hand-phone","provider":"Phone Repair Tools Machine Parts","version":"1.0","type":"link"}
