Glasses are generally optical lenses made of resin. Glasses should not have defects and have high surface finish requirements.

Compared to ordinary cutting tools, PCD milling cutters have the characteristics of high hardness, sharpness, wear resistance, high accuracy, and long service life. The use of PCD specialized forming tools on five axis machine tools is very suitable for milling glasses and lenses, which can achieve perfect precision machining of the surface and side edges of glasses.

The PCD processed glasses have advantages such as scratch free, high efficiency, and high gloss. At the same time, if the PCD glasses tool is worn out, it can also be repaired, and repair is cheaper.

According to the thickness and shape of the lenses, suitable PCD tools can be used to process glasses, and frames, achieving good results.
