Description

Technical Field

[0001] This utility model relates to the technical field of 2D cover plate processing, and in particular to a single-sided grinding device for sodium-calcium substrate 2D cover plates. Background Technology

[0002] Currently, mobile phone, industrial, and automotive cover glass products often use sodium-calcium substrate as glass cover glass to reduce costs. Sodium-calcium substrate float glass has poor alkali resistance and very poor scratch resistance, often requiring double-sided flat grinding and polishing before and after tempering. However, conventional polishing machines use blankets or brushes, which are not suitable for this purpose. Therefore, a single-sided grinding disc device for sodium-calcium substrate 2D cover glass is designed to adapt to sodium-calcium substrate as glass cover glass. It is also easy to replace, thus replacing the polishing machine and directly installing it on a single-sided polishing machine. This reduces the need for a demolding and cleaning process, thereby increasing work efficiency. Utility Model Content
