Abstract

ТВЕРДОСПЛАВНАЯ РЕЖУЩАЯ ПЛАСТИНА по авт. св. № 622585, отличающа с  тем, что, с целью повышени  долговечности режущей пластины путем снижени  уровн  напр жений в ее центре, боковые нерабочие стороны пластины выполнены дугообразными, причем радиус R их кривизны св зан с длиной L режущей кромки и толщиной Н пластины соотношени ми R 1,1L; R SOLID CUTTING PLATE according to ed. St. No. 622585, characterized in that, in order to increase the durability of the cutting plate by lowering the level of stresses at its center, the lateral non-working sides of the plate are arcuate, the radius R of their curvature being related to the length L of the cutting edge and the thickness H of the plate 1,1L; R
