An
automatic lens edger helps to increase edging productivity, as well as
flexibility through fast, accurate edging of simple and complex edge types. It
help in the efficient and fast production of straight bevels, inclined bevels, rimless
with drills, grooves, and polishing in addition to T-bevels and steps backs.
With the automatic edging machine, even the most complicated jobs are easily
edged.

History of automatic edging machine
The automatic edging machine was invented in
September 1953 and in July 25th 1967 and was granted patent right in
the United State in July 25th 1967 with Patent No 3,332172. In 2006,
the automatic edging machine enabled the most delicate jobs to be carried out
comfortably with customized setting.
