The fine grinding sheet is a tool used for finishing optical glass after roughing. In the roughing process, the surface of the optical glass may have some roughness and unevenness, which need to be further processed by the fine grinding sheet to make the surface more smooth and flat.

The fine grinding sheet is generally made of metal bond, such as diamond powder and metal powder mixed and sintered. The metal bond has high hardness and wear resistance, and can effectively finish the optical glass. The ultra-fine grinding sheet is generally used resin binder, resin binder has better strength and toughness, can be more finely processed, to obtain higher processing accuracy.

According to the physical characteristics of different optical glasses, different types of fine grinding sheets of bonding agents can be selected for processing to obtain better processing effects. For example, for optical glass with higher hardness, a fine grinding sheet of a metal bond with higher hardness can be selected for processing to ensure processing quality.

When using fine grinding plates for processing, it needs to be used in conjunction with coolant. The main function of the coolant is to cool the processing area and prevent the heat generated during the processing from causing damage to the optical glass and the fine grinding sheet. In addition, the coolant can also play a cleaning role, washing away the chips and particles generated during the processing, and maintaining the self-sharpness of the processing.

Fine grinding sheet is a kind of tool used for finishing optical glass after rough machining, and good processing effect can be obtained by selecting different types of bonding agents. When using the fine grinding plate, it needs to be used in conjunction with the coolant to maintain the processing self-sharpness.
