   <abstract xml:lang="ru">
    <p>В условиях санкционного давления и необходимости импортозамещения задача снижения затрат на запуск производства корпусов сборных свёрл приобретает особую актуальность. Цель данной работы заключается в снижении стоимости запуска производства такого корпусного инструмента за счёт внедрения новой технологии изготовления. Проведён сравнительный анализ двух производственных маршрутов: традиционного субтрактивного метода механической обработки и инновационного металл-композитного, сочетающего селективное лазерное плавление металлической оболочки с последующей вибро-вакуумной заливкой металлополимерного наполнителя. Показано, что комбинированная металл-композитная технология обеспечивает ряд конструктивных преимуществ, недостижимых при классическом подходе, включая формирование конформных внутренних каналов охлаждения и повышение виброустойчивости инструмента благодаря демпфирующему полимерному ядру. Установлено, что новая технология позволяет существенно снизить первоначальные затраты при мелкосерийном производстве корпусов свёрл, что подтверждает целесообразность её применения в условиях импортозамещения.</p>

    <p>In the conditions of sanctions pressure and the need for import substitution, the task of reducing the cost of starting production of prefabricated drill bodiess is becoming particularly relevant. The paper objective is to reduce the cost of starting production of such a tool by introducing a new manufacturing technology. A comparative analysis of two production routes is carried out: a traditional subtractive method of mechanical processing and an innovative metal-composite method combining selective laser melting of a metal shell with subsequent vibro-vacuum filling of a metal polymer filler. It is shown that the combined metal-composite technology provides a number of design advantages that are unattainable with the classical approach, including the formation of conformal internal cooling channels and increased vibration resistance of the tool due to a damping polymer core. It is found out that the new technology significantly reduces initial costs in small-scale production of drill bodies, which confirms the expediency of its use in the conditions of import substitution.</p>
