Способ абразивной обработки заготовки, включающий:наличие постоянно вращающегося связанного абразивного круга диаметром как минимум 150 миллиметров, причем связанный абразивный круг содержит керамические формованные абразивные частицы, удерживаемые в связующей среде; исоприкосновение вращающегося связанного абразивного круга с металлической заготовкой таким образом, что заготовка подвергается абразивной обработке с непрерывным образованием металлической стружки, причем средняя температура металлической заготовки не превышает 500°C, и при этом 20 вес.% металлической стружки представляет собой волоконную металлическую стружку длиной по меньшей мере 3 миллиметра (мм).2. Способ по п. 1, где как минимум 20 вес.% металлической стружки имеет волоконную структуру при длине стружки как минимум 10 мм.3. Способ по п. 1, где вращающийся связанный абразивный круг дополнительно содержит дробленые абразивные частицы.4. Способ по п. 1, где связка содержит отвержденную органическую связующую смолу.5. Способ по п. 1, где диаметр вращающегося связанного абразивного круга равен как минимум 350 мм.6. Способ по п. 1, где заготовка и вращающийся связанный абразивный круг вводятся в соприкосновение друг с другом для достижения скорости резки как минимум 20 см/с.7. Способ по п. 1, где заготовка и вращающийся связанный абразивный круг вводятся в соприкосновение друг с другом для достижения скорости резки как минимум 40 см/с.8. Способ по п. 1, где керамическим формованным абразивным частицам придана прецизионная форма.9. Способ по п. 1, где керамические формованные абразивные частицы включают в себя усеченные трехгранные пирамиды.10. Способ по п. 1, гд
