MECHANICAL ASSEMBLY MANUFACTURING CAPABILITIES

The peculiarity of mechanical assembly lies in the fact that all technological processes were based on the serial and mass production types, i.e. the main labour organization forms of the mechanical assembly shops are sequenced-flow and direct-flow production.

Most parts are machined in sequenced-flow machine-operated or automated lines. Sequenced-flow machine-operated lines basically (75-80%) consist of special-purpose multispindle or multistation machines, which require manufacturing of heavy and large-size units (rotary tables, multispindle heads, etc.) for another product changeover and readjustment.

Altogether, mechanical assembly involves 1 240 metal working machines, including 26 automated lines and 45 different cold-forming presses.
