Представлены особенности работы замкового соединения буровой штанги, и проблемы, возникающие при формировании микрогеометрии резьбы. Предложен метод магнитно-абразивного полирования наружной и внутренней резьбовой поверхности замкового соединения. Рассмотрен способ определения магнитных сил в рабочем пространстве устройства для магнитно-абразивной обработки. Показано применение программной среды ANSYS Maxwell для расчета величины магнитной индукции в межполюсном пространстве. Приведен анализ распределения магнитных сил в межполюсном пространстве при различных модификациях полюсных магнитов, позволяющий определить наиболее эффективный конструктив магнитного наконечника. Полученные результаты позволяют определить условия технологического обеспечения равномерного поверхностного слоя резьбовой поверхности замкового соединения буровой штанги.
