Abstract

Инструментът намира приложение за прорязване на прсътеновидни отвори в метален обработваем детайл. При работа с него се избягва задръстването на жлебовете му с метални стружки, което води до повишаване на ефективността му и се създава възмож ност за работа спо-малък въртящ момент. Инструментът включва тяло с цилиндрична странична стена с множество зъби, съединени помежду си с кръгово разположени ребра, и множество жлебове, простиращи се нагоре от долния край на страничната стена. Зъбите имат радиален вътрешен режещ ръб, радиален междинен режещ ръб и радиален външен режещ ръб. Вътрешните и междинните режещи ръбове са оформени на жлебовете с възможност за рязане на отделна стружка, като общата им ширина е равна поне на дебелината на жлебовете. Вътрешните и междинните режещи ръбове са с радиална големина, по-малка от дебелината на жлебовета, които са оформени с междузъбия, простиращи се нагоре от режещите ръбове и излизащи в радиален съседен жлеб, страничните стени на който са очертани от външните режещи ръбове. Всеки жлеб е с радиален размер, не по-малък от размерите на вътрешния и междинния режещ ръб, и с кръгов размер, по-голям от радиалния. Стружките образувани от вътрешния и междинния режещ ръб на ребрата, са насочени нагоре през техните съответни междузъбия и в радиалния съседен жлеб. 19 претенции, 15 фигуриThe tool is used for cutting annular holes in a metal workpiece. When working with it, clogging of its grooves with metal chips is avoided, which leads to an increase in its efficiency and creates the possibility of working with a lower torque. The tool includes a body with a cylindrical side wall with a plurality of teeth connected to each other by circularly arranged ribs, and a plurality of grooves extending upward from the lower end of the side wall. The teeth have a radial inner cutting edge, a radial intermediate cutting edge and a radial outer cutting edge. The inner and intermediate cutting edges are formed on the grooves with the ability to cut a separate chip, their total width being at least equal to the thickness of the grooves. The inner and intermediate cutting edges are of a radial size less than the thickness of the grooves, which are formed with interdentations extending upwardly from the cutting edges and extending into a radially adjacent groove, the side walls of which are defined by the outer cutting edges. Each groove has a radial size not less than the dimensions of the inner and intermediate cutting edges, and a circular size greater than the radial. The chips formed by the inner and intermediate cutting edges of the ribs are directed upwardly through their respective interdentations and into the radially adjacent groove. 19 claims, 15 figures
