  Over the last 10 years (1999-2009) within the frames of realization of the large-scale program on technical re-equipment the machinery equipment of NKMZ has been significantly renovated. Today the new high-performance equipment in the company amounts to some 200 units. Here belong CNC machining centers equipped with the required attachments and tool magazines of such world famous producers as "Waldrich Coburg", "Hercules", Union, Auerbach (Germany), "Tos Varnsdorf", "Tos Kurim", "Skoda" (Czechia), Ferrari (Italy) and others. In doing so, obsolete equipment is withdrawn from the process. Application in the design of the new machines of the latest achievements in the field of machine-tool building enables to obtain high accuracy of the work pieces being machined. Sinumeric 840D CNC system provided for these machines permits machining of the products with the intricate shape in automatically controlled mode with the minimum number of resettings that results in the increase in efficiency up to 2-5 times as compared with machining in the universal equipment.


BORING AND MILLING MACHINES




		High-efficiency machining of large box-like workpieces as per the 7th grade of accuracy with the roughness of Ra 1,6 зm is performed in the multioperation CNC machines fitted with the attachments and tools magazines as per control programs   The possibility exists to machine box-like parts up to 5000 mm high and 33000 mm long (e.g., press clamps) in the coupled (common columns guides) horizontal boring machine tools produced by "SKODA"   Large-scale works are underway in the company referring to the revamping of the heavy-duty boring machine-tools produced by "Skoda" (Czechia), "Schiess" (Germany), "INSSE" (Italy) that include bringing their accuracy to the original ratings and provision with the up-to-date computer numerical control systems, tool magazines, measuring systems.
		High-precision machining of the parts under control programs in the machining centers of "Waldrich Coburg", Union, Auerbach (Germany), "Tos Kurim" (Czechia), Ferrari (Italy).

DEEP-HOLE DRILLING MACHINES




NKMZ has a vast experience in the manufacture of high-quality hydraulic cylinders with a wide range of diameters and lengths, due to having deep-hole boring, internal grinding and honing machines of such famous companies as: "TACCHI", "KZTS" (Ukraine) "GEHRING" fitted with rolled headers, diamond grinding tools of the leading tools-producing companies such as "S.Coromant", "Seco" and others, measuring and check facilities.
		The plane-milling machine updated by NKMZ with the table lifting capacity of 40 tons provides for the gun drilling of the holes with the diameter between 10 and 32 mm and the depth up to 3000 mm in the box-like parts and long shafts to be made.




GEAR PRODUCING MACHINES




		Gear machining equipment numbering over 70 machine-tools includes machining centers produced by "Gleason-Pfauter". Two of them that are vertical gear milling machines machine the gears with worm milling cutters of ЂЂ class providing the 7th degree of accuracy of mesh. P2000G and P800G gear grinding machines possessing high performances are capable of producing gear wheels of the 4th degree of accuracy of mesh.

 



TURNING-AND-BORING MACHINES

 


	Continuously improved are the methods of processing the workpieces of difficult-to-machine high-alloy steels, high strength chilled cast irons. Turning-and-boring lathes available with the company are capable of machining the parts with the diameter up to 12500 mm, the height up to 5000 mm and the weight up to 200 tons.






BANDSAW MACHINES




		Cutting sinkheads and excesses of forgings and cutting the workpieces are performed in the bandsaw machines produced by "EVERISING" (Taiwan).



LATHES

 

Machining facilities of NKMZ are represented by the park of the unique CNC lathes produced by such famous companies as Kovosvit (Czechia), "Boeringer", "WALDRICH SIEGEN", "HOESCH" (Germany), "KZTS"(Ukraine) that are capable of machining the cylinders, bands, shafts, rods, with the length up to 24000 mm and more, up to 3000 mm in diameter and weighing up to 250 tons.






GRINDING AND HONING MACHINES

 


ELECTROPLATING




There is a provision for applying various types of electroplating: chromium, zinc, cadmium plating, phosphatizing and oxidizing..

ASSEMBLING FACILITIES




Assembling facilities make it possible to perform check assembly and tests of the machines with overall dimensions up to 21 m high, up to 150 m long and the total weight of about 2000 t (mill stands, cranes, reloaders and etc.)
