The technological re-equipment program undertaken by NPO Saturn is implemented through purchasing of up-to-date multifunctional equipment and connecting it to the integrated information network, establishing specialized production lines and areas.
This enables carrying out various types of gas-turbine engine parts processing to a high degree of accuracy and reproducibility in the shortest possible time to specified parameters.
NPO Saturn has at its disposal production facilities enabling manufacture of gas-turbine components of any complexity, dimensions and mechanical characteristics.
The metal-processing equipment stock amounts to over 12,000 units, including about 2000 units of metallurgical equipment.
Automated production lines and ÑNÑ machines amount to over 40% of the total equipment quantity in some production directions.
The production basis includes casting, welding, machining, heat treatment, metal forming, and tooling.
Science-intensive technologies for manufacturing parts of composites, structural ceramics, and bimetals are widely used in pilot and series production.
Volume of investments in purchasing new equipment amounts to more than 3 bln. roubles.
Currently, at NPO Saturn within the scope of the through design-manufacture program on the basis of the integrated information system the following has been implemented:
- Simultaneous product design, development of processes and manufacture of tooling on the basis of 3D models;
- Integrated electronic database of manufacturing processes and documentation;
- QuickCast build style pattern (stereolythography) of the most complex parts;
- Industrial network of data transmission to CNC machines;
- Automated production planning system;
- Automated production cost accounting system.
