Technical Field

The invention relates to the technical field of edge grinding machines, in particular to a pressure balancing and automatic adjusting system for a nose of a glasses edge grinding machine.

Background

In the eyeglass industry, optical lenses are classified according to hydrophobic coating, and include general film lenses, super-coated lenses, and the like, wherein the ratio of super-coated films to super-coated films has risen to a high level. In recent years, the surface smoothness of the film layer is gradually improved along with the improvement of the process of lens coating, and the direct influence is the improvement of the waterproof performance and the beautification of the spectacle lens, and the lens coating is also favored by consumers. Most of the waterproof optical lenses have extremely low surface friction coefficient.

When the full-automatic edge grinding machine is used for processing the super-filming lens and the super-filming lens, the problem of shaft running is difficult to solve. Once the deviation of the astigmatism axis of the processed lens exceeds 5 degrees, the user feels obvious discomfort when using the lens. Some lenses with excessive axis deviation can only be discarded. A considerable proportion of the opticians choose to use manual edging machines for edging these lenses, which is not only cumbersome to operate, but also places high demands on the optician's finishing skills.
