Description
такте с обрабатьтаемой поверхностью режущие кромки абразивных зерен глубже внедр ютс в нее. При этом значительно возрастает глубина мнкрорезани и силы резани , увеличиваетс съем металла, иитеисифицируетс процесс обработки . Микротвердостъ обра&этанной поверхности повышаетс вследствие более высокой степени пластического деформировани металла поверхностного сло по сравнению с обработкой без шариков, что увеличивает износостойкость поверхности и долговечность работы деталей.With the surface to be treated, the cutting edges of the abrasive grains are more deeply embedded in it. This significantly increases the depth of cutting and the cutting force, increases the removal of metal, and processes are processed. The microhardness of the surface of the etane surface increases due to a higher degree of plastic deformation of the metal of the surface layer as compared to the treatment without balls, which increases the wear resistance of the surface and the durability of the parts.
Твердость материала, из которого изготовлены шарики, должна быть меньше твердости обрабатываемы} деталей, чтобы обеспечить шаржирование поверхнскти абразивными зернами и исключить повреждение обрабатываемой поверхности шариками.The hardness of the material from which the balls are made must be less than the hardness of the parts processed in order to provide a caricature of the surface with abrasive grains and to prevent damage to the surface being treated with balls.
Рекомевдуемое весовое соотношение шариков и абразивных зерен 1:3. Размер шариков гюд&(рают в соответствии с наименьшими радиусами кривизны профил поверхности обрабатываемых деталей. Врем обработки при аналогичных режимах сокращаетс на 30%.The recommended weight ratio of balls and abrasive grains is 1: 3. The size of the guid balls &
При этом производительность увеличиваетс на 25-30%, а микротвердость металла поверхностного сло повышаетс на 15-20%.At the same time, the productivity increases by 25-30%, and the microhardness of the metal of the surface layer increases by 15-20%.
В качестве твердого наполнител иожно использовать и металлические трех- или четырехфанные призмы.Metallic three- or four-member prisms can also be used as a solid filler.
