A set of seven posts by Robert Olech of LensTip, about an earlier visit to Sigma’s Aizu factory can be found at:
https://www.lenstip.com/142.1-article-A_trip_to_Sigma_lens_factory_in_Aizu_Introduction.html

The posts concentrate on the lens production process, and comprise:
- Introduction
- Metal Processing
- Presses
- Painting
- Optics
- Assembly & Quality Control
- Summary

The posts include many illustrative photographs
And many of the same processes would also apply to the production of other optics such as binoculars

Robert also interviewed the Sigma CEO Kazuto Yamaki: https://www.lenstip.com/143.1-article-Interview_with_Kazuto_Yamaki_-_CEO_of_Sigma_Corporation.html
