Description

technical field [0001] The invention relates to the fields of optical manufacturing and optical material processing, in particular to a design and manufacturing method for a special-shaped polishing disc used in a double-rotor numerical control polishing machine. Background technique [0002] Traditional optical polishing methods have low processing efficiency, long cycle time, and rely heavily on the experience of processing personnel, which can no longer meet the processing needs of modern optical components. The emergence of computer technology has given birth to modern precision numerical control polishing technology based on numerical control technology. The CNC polishing technology uses a small-sized polishing disc, which can fit well with the local area of ​​the surface of the component to be processed, so as to obtain higher processing accuracy; due to the use of computer-controlled polishing discs for processing, compared with traditional processing methods, The ju...
