Biography
Born in the 1880s. Received an engineering education.
From a young age he worked at the Red Proletarian plant (until 1922, the Society of Mechanical Plants of the Bromley Brothers ).
In the 1940s, he developed lathe chucks with mechanical clamping for universal lathes DIP-200 and 1K62. Due to the special arrangement of the Archimedean spiral, the cams never “held backwards”, which usually occurs in universal cartridges, but always clamped the part with the entire plane. The cartridge has never become clogged with chips, whereas usually it is precisely because of the clogging with chips that the cartridges quickly fail.
- Stalin Prize of the third degree (1947) - for the development of the design and development in the production of a series of machines for turning carriage axles
