Working principle: as shown in fig. 1 and 2, when the device in the present case works, a user holds and fixes the lens between the left holding shaft and the right holding shaft, and the lens is driven by the holding shaft to rotate at a certain rotation speed. In the process of grinding the lens, not only the outer circle of the lens needs to be ground, but also the left side and the right side of the lens need to be chamfered. Therefore, the grinding surface of the grinding wheel is concave with a low middle and high sides. The grinding wheel grinds the excircle by utilizing the inner groove part, and chamfer the lens by utilizing the round tables with two convex sides.

Compared with the traditional technology adopting a hand wheel drive mode or a mode that a mechanical gear and a cam control grinding wheel are used for displacement feeding, in the scheme, automatic adjustable feeding is realized through the movement of a transverse sliding table and a longitudinal sliding table driven by a servo motor. When a user produces lenses of different models, the user only needs to carry out parameter design in the control system, so that the mechanical structure is not required to be adjusted. The device has high production speed, does not need to adjust mechanical parts of the device, greatly improves the production efficiency and the production precision of the device, and can be widely popularized and used.
