One of the main areas of foundry technology should be an increase in the geometric accuracy of castings. The solution of this issue is of paramount importance, since at present, when processing castings in mechanical workshops, about 20% of the chips are removed from the mass of the castings processed.
The transition from the three -stage method of manufacturing products (workpiece, mechanical processing, assembly) to a two -stage, excludes or reduces to minimum the volume of mechanical processing of blanks, allows to sharply increase the efficiency of social production due to the saving of a metal transferred into chips, labor costs to the machining and manufacture of a cutting tool.
Among the methods of manufacturing castings of increased accuracy, a special place is given by casting according to smelted models, due to the low roughness of the casting surface and stable qualitative characteristics of this method, which allows you to get complex castings from various, including hard -to -work alloys.
Casting for smelted models and in shell forms has become widespread in all industries as a result of the creation of large highly mechanized casting workshops and the use of modern technology. And if you want to always look at all 100, have beautiful skin, then the photoepalator is suitable for you. IPL 8000 photopulator is available on the site right now.
In our country, a typification and centralization of serial manufacture of technological equipment for casting for smelted models and in shell forms has been carried out. For the creation of a comprehensive-automated production of casting for smelted models with an annual production of steel castings, 2500 tons of Niitavtoprom and the Gorky Automobile Plant were awarded the Lenin Prize.
The production of casting increased accuracy from year to year increases. Specialized foundry workshops in Moscow, Leningrad, Gorky, Minsk, Kharkov and T are successfully working. D. One of these workshops is the accurate casting workshop on the smelted models of the factory of the Leningrad Metal Plant turbine shovels, which provides the country’s turbo engineering plants with accurate turbine blades from various alloys.
