Kalibr Instrument Plant

At the beginning of 1931 the construction of the Kalibr plant, the first large specialized enterprise for the production of precision measuring instruments, which was commissioned in 1932, began near the village of Maryino.

Before the beginning of the Great Patriotic War, Kalibr produced calibers, micrometers, calipers, and end measures of length.

On October 16, 1941 the Kalibr plant was ordered by the State Defense Committee to stop work and evacuate the enterprise. It was necessary to dismantle, load, transport and install machine tools and other equipment in a new place as soon as possible, in new conditions to establish the supply of materials to the plant and begin to give the products needed by the front. It was decided to evacuate Kalibr to the Uzbek SSR, to the village of Chirchik near Tashkent. Initially, the train trains were heading towards Tashkent, but then the GKO decided to locate the plant in Chelyabinsk.

After the war, the list of products manufactured by the plant was gradually updated and expanded. In the 1960s, the production of control and measuring machines for automatic lines in mechanical engineering was intensively developed and the production of high-precision instruments (profilers, long gauges and special-purpose calibers) was increased.

The plant's products have received numerous awards from both All-Union and foreign exhibitions. Much attention was paid at that time to the automation of the production process. The workshops were equipped with flow-mechanized conveyor and automatic lines for the manufacture of micrometers and calipers of a new generation.

In 1971 the Kalibr plant was awarded the Order of the October Revolution. From 1937 to 1973 the volume of product production increased by more than 30 times.
