The machine-building complex of "Motovi-likhinskiye zavody" is constructed by a principle subject - technological specialization on base of the technologically closed work shops and sites. It allows to make all types of treatment of details with a diameter up to 5000 mm and length up to 12000 mm.

First of all, the generated complex of the technological equipment is focused on manufacture of special equipment.

For the first time in world practice at the enterprise is developed and mastered forging technology of hollow precision blanks of artillery barrels on radial-forging machines. Subsequent deformation-free thermal treatment of blanks by currents of commercial frequency (CCF) on special installations, and also unique by its science capacity machining of barrels, has allowed to provide their high mechanical properties (yield strength up to 1400 MPa, impact strength at low temperatures 4 - 4,5 kg.m/mm2), parameters of accuracy and operational characteristics.

The proportion of the high-efficiency equipment in a total stock of metal-cutting lathes makes more than 40 %.

Treatment of artillery barrels, supporting - rotary devices, large welded construction, pneumatic-hydraulic equipment and pipelines is made on the precision equipment, such as:

• special machine tools for treatment of deep bores, lathes, milling and other machine tools for execution of unique operations;
• CNC machine tools, including the new layout decisions such as "the processing center";
• vertical lathes, plano - milling and horizontal -boring equipment;
• complex of the gear-cutting equipment;
• complex of the equipment for manufacturing of the hydraulic equipment and piping;
• complex of pressing equipment from 16 up to 1250 t for manufacturing details and blanks from a sheet material.

At the enterprise the high-accuracy technologies of machining of gun barrels are mastered, which are based on methods of active control of geometrical parameters (variations of wall thickness, the straightness of bores and stress-strained status of blank in all main operations of technological process). The treatment of barrels and details of artillery systems is made on the specialized high-efficiency equipment connected in united product lines and automated complexes. The great importance in machining manufacture is given to finishing technologies considerably determining efficiency of separate mechanisms and products as a whole.

At the enterprise the new honing methods of bushings' openings of power hydraulic cylinders with dosage submission of abrasive bars are applied, that allows to provide stably their accuracy and complex of parameters of working surfaces' roughness with most full responding to reliability of cylinders at operation.

Have received the further development:

• technology of precision grinding of control hydraulics' details (slide valves, valves, pistons) and tools;
• grinding by elastic abrasive tools and tools from super-abrasive;
• methods of dimensional - strengthening treatment.

The considerable increase of quality, decrease of labour intensiveness - all this has appeared with the development of welding technology of long half-made products of box-shape type with automatic welding of internal and outside seams, at which the control of a joint is carried out by the special electronic device - control sensor providing high quality of welded seams. The installation allows to make welding of products with the length up to 11000 mm.

The decision of complex technological tasks is carried out on the basis of new technologies' development of electrophysical and electrochemical treatment.

At the enterprise the process of electro-erosional treatment of curvilinear openings in breech-block group details is mastered. The increase of durability of artillery systems is achieved by chromizing of its most heat-tensity parts. The preparation of inner for chromizing is carried out on the modernized machine tool RT 294 by specially developed for this purpose tool.

Complex of the modern equipment and the developed specialized technological processes allow to carry out treatment of difficultly - profile surfaces of stamps and press - forms with high accuracy, and also to make treatment and laser cutting of details with a complex configuration with a high degree of precision (precision of cutting with the tolerances 0,05 mm) from common machine building and hardtreated materials.

With the purposes of reception of flexible system for manufacture's preparation of new details from a plate, the complex from the laser cutting machine (range of thickness from 1 up to 16 mm, length of cutting up to 4000 mm) and CNC bending machine (length of bend up to 4000 mm, thickness of a bending material up to 8 mm) has put in service. Laser cutting of plate allows to cut out clean details with accuracy of 0,1 mm in all range of thickness with a roughness of cut Ra 12,5. Two rests (with precision of positioning 0,04mm) and bending beam (with precision 0,06mm) are controlled by the computer in bending machine. This complex allow to receive complex configurations in heat-treated plate material without manufacturing of stamps. Beside this the complex has allowed to increase dimensions of the bent details such as channel.

Automated mechanical & assembling complexes and lines on a basis of treatment centers and CNC machine tools on production of complex and precise frame details with the sizes up to 1250 mm are organized in main work shops.

Made production at all stages is exposed to the careful control.

The sequence of all operations is constantly checked according to the given technology.

The completely automated laboratories for the special control after the main parameters and characteristics of the barrels, breech pieces, wedges, cylinders and other components of the artillery equipment are provided with quality of artillery systems appropriate to the requirements of the world standards, that makes sure by the certificates of Russian official organizations. The system of quality ISO 9001 is introduced at the enterprise .
