Abstract
Инструментът намира приложение в машиностроенето за прорязване на отвори в заготовки. С него се осигурява повишена точност и гладкост на обработвания отвор, като освен това има и възможност за работа с по-голямо натоварване. Инструментът се състои от цилиндрично стебло /12/, снабдено в долния си край с множество зъби /16/ и канали //18/, разположени равномерно по периферията му. Разстоянието от вертикалната линия до линията на пресичане на вътрешната периферия със задната повърхнина на всяко междузъбие е по-малко от 1,016 мм. В стеблото /12/ на инструмента /10/, по оста му, е разположен канал за охлаждаща течност /54/. Пространството /50/ между вътрешната периферия на зъба и централната част на материала е оформено като канал, простиращ се от вътрешната страна на всеки зъб /16/ радиално назад към следващото го междузъбие /28, 30/. Каналът /50/ е оформен от равнина /46/, наклонена радиално и навън под ъгъл, не по-малък от 3 до 70, така че радиалният му размер расте прогресивно в посока назад. 3 претенции, 5 фигури.The tool is used in mechanical engineering to cut holes in workpieces. With it, increased accuracy and smoothness of the machined hole is ensured, and there is also the possibility of working with a greater load. The tool consists of a cylindrical stem /12/, equipped at its lower end with multiple teeth /16/ and grooves //18/, evenly spaced along its periphery. The distance from the vertical line to the line of intersection of the inner periphery with the posterior surface of each tooth is less than 1.016 mm. In the stem /12/ of the tool /10/, along its axis, a coolant channel /54/ is located. The space /50/ between the inner periphery of the tooth and the central part of the material is formed as a channel extending from the inner side of each tooth /16/ radially back to its next interdental /28, 30/. The channel /50/ is formed by a plane /46/ inclined radially and outwards at an angle of not less than 3 to 70, so that its radial size grows progressively in the rearward direction. 3 claims, 5 figures.
