Description

Technical Field

[0001] The present invention relates to the technical field of camera lens polishing, in particular to a double-sided polishing machine and a polishing method for a large-size video surveillance camera lens. Background Art

[0002] The lens of a video surveillance camera is a vital component of the camera. It is responsible for focusing light and projecting it onto the camera's sensor to generate a clear image. The lens needs to be processed before leaving the factory, such as lens polishing. The polishing process of the surveillance camera lens is a delicate and critical process, which directly affects the camera's imaging quality and clarity.
