Abstract
1. Режущий инструмент для горных машин, включающий закрепленный на державке полый симметричный корпус с рабочей головкой, имеющей кольцевую режущую кромку, образованную сопряжением наружной и внутренней конических поверхностей, отличающийся тем, что, с целью повышения эффективности процесса резания, толщина корпуса в продольном сечении рабочей головки уменьшается по длине в направлении от рабочей головки и определяется из соотношенияh-h= 0,3•t ,где h- максимальная толщина корпуса рабочей головки, мм;h- минимальная толщина корпуса рабочей головки, мм;t- длина корпуса рабочей головки, мм.2. Инструмент по п.1, отличающийся тем, что внутренняя поверхность корпуса рабочей головки выполнена с кольцевыми проточками.1. Cutting tool for mining machines, including a hollow symmetric body mounted on a holder with a working head having an annular cutting edge formed by matching the outer and inner conical surfaces, characterized in that, in order to increase the efficiency of the cutting process, the thickness of the body in the longitudinal section heads decreases in length in the direction from the working head and is determined by the ratio h-h = 0.3 • t, where h is the maximum thickness of the working head, mm; h is the minimum thickness of the working head olovki mm; t- working length of the head body, mm.2. The tool according to claim 1, characterized in that the inner surface of the housing of the working head is made with annular grooves.
