FIELD: process engineering. ^ SUBSTANCE: rotary plate comprises two opposite, in fact, square location surfaces turned relative to each other about central axis located perpendicular to said surfaces, and four identical face surfaces. Note here that principal cutting edge is located between every location surface and every face surface. Every face surface has two angular edges opposed along diagonal line to make auxiliary cutting edge adjoining the main cutting edge. Every face surface has two recessed flutes that pass from appropriate angular edge along appropriate principal cutting edge to its rear end, while support surface is arranged between two flutes 7 to run in symmetry beyond the ends of adjoining flute across the principal cutting edge. ^ EFFECT: reliable attachment of cutter plate. ^ 19 cl, 5 dwg |
