The polishing process of optical glass lenses is an important process step to achieve surface smoothness and flatness of optical lenses. Below we will introduce a commonly used optical glass lens polishing process.

The following materials and equipment need to be prepared: optical glass lenses, sandpaper, grinding fluid, polishing fluid, polishing machine, polishing cloth, etc.

The first step is grinding. Place the optical glass lens on a flat workbench and grind it evenly with sandpaper and appropriate grinding fluid. The role of the grinding fluid is to reduce the friction between the sandpaper and the lens surface and improve the grinding effect. Grinding should pay attention to the strength should be uniform, to avoid excessive grinding caused by glass surface damage.

The second step is polishing. The ground lens is polished by a polishing machine. First, pour the polishing liquid into the polishing disc of the polishing machine and apply it evenly on the surface of the glass lens. The lens is then placed on a polishing disc and polished with appropriate pressure and angle. The polishing liquid plays the role of lubrication and removal of grinding marks. When polishing, keep a low speed and an appropriate amount of lubricant to prevent the surface temperature from being too high.

The third step is cleaning. After polishing, remove the lens and rinse it with clean water to remove the polishing liquid and residue on the surface. Then, gently wipe the surface with a polishing cloth and let it dry.

Quality inspection. Use optical instruments to test the lens and evaluate whether its finish and flatness meet the requirements. If defects or unqualified places are found, the grinding and polishing steps can be repeated until the requirements are met.

The polishing process of optical glass lenses includes grinding, polishing, cleaning and quality inspection. This process can effectively improve the surface quality of optical lenses and ensure their performance in optical applications. In actual operation, it is necessary to pay attention to the control of strength, angle and lubricant, and carefully check the polished lens to ensure that the polishing effect meets the requirements.
