Abstract

Изобретение относитс  к машиностроению , к механической обработке глубоких прецизионных отверстий малых диаметров и позвол ет повысить качество обработки путем обеспечени  пр молинейности обрабатываемого отверсти . Дл  этого в инструменте дл  обработки отверстий, содержащем рабочий элемент, установленный с возможностью взаимодействи  с торцами толкателей 5, размещенных оппозитно друг другу, рабочий элемент выполнен в виде тонкостенной втулки с перемычкой 4 в средней части. Торцы толкателей при этом и перемычки выполнены сферическими с радиусом сферы перемычки, большим радиуса сферы толкателей. 1 ил.The invention relates to mechanical engineering, to the machining of deep precision holes of small diameters and allows to improve the quality of processing by ensuring the straightness of the machined hole. For this purpose, in a hole processing tool containing a working element mounted to cooperate with the ends of the pushers 5 placed opposite each other, the working element is made in the form of a thin-walled sleeve with a jumper 4 in the middle part. In this case, the ends of the pushers and the jumpers are made spherical with the radius of the sphere of the jumper greater than the radius of the sphere of the pushers. 1 ill.
