Abstract

Изобретение относитс  к обработке металлов резанием и может использоватьс  при расточке глубоких отверстий. Целью изобретени   вл етс  повышение точности обработки благодар  увеличению несущей способности направл ющих борштанги. При подаче СОЖ по каналу 2 корпуса направл ющие 4 выдвигаютс  из пазов 3, расположенных тангенциально, до образовани  со стенкой 10 обрабатываемого отверсти  жесткого идростатического сло , тем самым предохран   от изгиба корпус борштанги. 2 ил.The invention relates to metal cutting and can be used when bore deep holes. The aim of the invention is to improve the machining accuracy due to an increase in the bearing capacity of the boring guides. When coolant is applied through the channel 2 of the housing, the guides 4 are pulled out of the grooves 3 located tangentially until a rigid and static layer is formed with the hole 10 of the machined hole, thereby protecting the boring housing from bending. 2 Il.
