Application fields
Optical glass polishing, such as K9 and quartz glass. The GM series of high-precision rare earth polishing powder is suitable for optical glass with a wear degree between 100 and 200. It features fast cutting speed, high precision, and easy cleaning.
Usage method
The recommended specific gravity is 1.03 - 1.10, which is determined by the type of nitrocellulose and the process.
Applicable machines: Flat high-throwing machine or spherical pendulum machine
Applicable workpieces: spherical lenses with wear degrees ranging from 100 to 200, and high-precision flat glass, such as prisms and master disk glass.
Features
The white polishing powder made from rare earth carbonates as raw materials through fluorination roasting can be used in the processing of optical glass.
The average particle size is 0.6 - 1.8 μm, with the maximum particle size being less than 12 μm, which can meet the precision requirements of optical components.
High polishing accuracy and easy to clean.
