The inquiry on technologies OJSC «Minsk Watch Plant»
Open Society "Minsk watch plant" has the qualified experts, the precision universal and special equipment for performance of a wide spectrum of the works connected with manufacturing of products of an instrument-making structure, and also wide scale of the diversified machine-building works.
For manufacture of external design of man's and female wristwatch, and also desktop and wall clock the processing centers with digital program control of the Swiss firm "Bumotec" manufacturing are applied, allowing to process black and nonferrous metals with accuracy of performance of the linear dimensions up to 0,01 mm and the maximal diameter of processing 60 mm.
At manufacturing of some products are used soldering installations for high-temperature soldering of nonferrous metals and alloys with silver solders, including performance of works on a jeweler soldering of details.
Painting instruments, for spraying protective and decorative coverings on a surface of metals and alloys with the painting chamber sizes 600x600 mm are available.
At manufacturing of watch dials, measuring rulers, scales with use of steel cliches the technology of tampon printing is widely applied to drawing precision prints in the maximal size 60x60 mm.
Available at the factory the forge-and-press equipment enables to carry out dividing operations, operations of cold extrusion and hot punching of brass and steel sheet material in a wide range of the sizes. The maximal effort developed by press is 400 tons.
The wide nomenclature of plastic details is made on thermoplast processing equipment of the domestic and import manufacture, providing accuracy of foundry, sufficient for details of man's and female wristwatch movements, and also any other products in weight from 20 up to 270 gram.
The enterprise has extensive park of the universal metal-working machinery of manufacture of the CIS countries, allowing to process details of machine-building profile with admissions up to 0,01 mm, and also the import universal equipment providing accuracy of processing up to 0,001 mm.
Tool manufacture of the factory is equipped with the Japanese spark-erosion equipment, allowing to process any current-carrying materials with accuracy of positioning up to 0,005 mm.
The import (Swiss) equipment allows to produce equipment and the tool of high quality. Thread-cutting, tool-grinding, relieving machines etc enable to make various blade instrument with high cleanliness of processable surfaces and admissions for the executive sizes in some cases up to 0,0002 mm.
There are technologies and the equipment for sintering and the subsequent processing hard-alloy products (plugs up to 10 mm in diameter, disks up to 60 mm), various trailer, castle-type and cylindrical mills, both from tool steel and from hard alloys.
Designing and manufacturing of production of a machine-tool constructing structure is made in case of need: the desktop universal turning and milling machine tools, the special process equipment. For example, the equipment designed and made by forces of the Open Society "Minsk watch plant" is working for a long time, allowing successfully to produce manometrical tubes for manometers.
A machine-tool constructing base available at the factory allows to project and make automatic transfer lines for assembly of products of exact mechanical engineering, and also any other products dose on overall dimensions to a wristwatch.
At the factory there is the Swiss special precision equipment, allowing to make cutting and the subsequent polishing of gear structures with height of a tooth from 0,1 up to 1 mm on cylindrical and face surfaces. At that, the cleanliness of processing of working surfaces of gear wheels at a level of the highest world standards is provided.
The extensive park of import turning automatic devices of longitudinal turning allows to organize mass manufacturing of details of type of bodies of rotation with the maximal diameter up to 10 mm and accuracy of processing up to 0,01 mm.
French and also own manufacturing equipment enables to make watch and instrument spirals of special alloys, and also from black and color hire in external diameter up to 15 mm. Thus accuracy of cross-section section of a structure of a spiral up to 0,0005 mm is provided.
Winding of coils by a wire by section from 0,016 mm up to 0,3 mm with a limiting dimension of 10 mm and number of coils up to 20 thousand can be made.
Heat treatment of details is made both with application of vacuum furnaces and furnaces with shielding mediums.
Protective and decorative anticorrosive coverings are widely applied: chemical and galvanic nickel plating, chromium plating, gilding, silvering, cadmium-plating, oxidation, zinc-plating and also coverings in ionic-plasma installations: nitride of the titan, nitride of zirconium, firm gold, diamond-like carbon covering with thickness up to 0,3 millimicrons etc. on details of products of instrument making and also on subjects of household use.
The factory has an opportunity to make printed-circuit boards of 4-th - 5-th class of accuracy with use positive and tenting technologies and to put sheetings on the basis of alloys tin-lead, nickel-pine forest, immersion gold, immersion tin.
The site of assembly of electronic blocks makes stuffing, the soldering and soft boiling of electronic components of printed-circuit boards, installation of body-free microcircuits from times-cookings and hermetic sealing. Thus the equipment of manufacture of the CIS countries is applied.
Existing technological processes of microelectronic manufacture allow to produce in mass scale boards for telephone cards, electronic keys of door intercommunication systems, boards glucometers and other products of household and special purpose.
