[0002] The lens processing and edging device has the following important functions. It can process the lens blank into the required accurate size. Different optical applications have strict requirements on the diameter, thickness and other dimensions of the lens. The edging device can accurately control these parameters to make the lens perfectly match the mounting component or optical system, avoiding installation difficulties or optical performance degradation due to dimensional deviation. Through fine edging processing, the edge of the lens can be made smooth and flat, and the surface roughness can be reduced. Rough edges may cause scattering and reflection, reduce the transmittance and imaging clarity of the lens, and improve the assembly efficiency and stability of the optical system.

Vibration may occur when the lens rotates, causing the lens to become loose. The processing accuracy is low, and the possibility of safety accidents caused by equipment failure or improper operation is increased. Utility Model Content
