It is easy to operate and reduces the risk of debris. One person can operate multiple devices at the same time. In addition, the jig mechanism cooperates with the lifting mechanism to assist polishing. The flat and curved surface of the workpiece solves the problem that the traditional polishing equipment cannot polish the concave surface of the glass. The equipment has a compact structure and tight protection, which can effectively save space on the site, and the surrounding environment of the equipment is cleaner. The replacement of fixtures and polishing wheels is fast and convenient, reducing maintenance costs, and it is easy to realize the on-line production of the whole line.
