TYPESETTING MILLING CUTTER Russian patent published in 1995 - IPC

FIELD: wood-working industry. SUBSTANCE: typesetting milling cutter has shaft 1 with milling cutters 4 having cutting edges located with the angular displacement. Milling cutters 4 are made in the form of two-blade milling cutters having stop surfaces opposite to the cutting edges in the planes perpendicular to the diametral plane of the milling cutter and through grooves in the face surfaces. In the projection onto the face plane of the milling cutter the groove walls form with the stop surfaces the angle α = 360^°/n, where n the number of milling cutters 4. A set of milling cutters 4 is connected by means of shaft 1 with nut 15 interacting with the thread of shaft 1. From the side of the set of elementary milling cutters, on part of its length nut 15 has segment 15 a with the cross-section in the shape of at least part of a polygon with the angle β between the sides determined according to the formula β = 180·[(n-2)/n]^° and shaft 1 has prop 2 on the end opposite to the thread for contacting with extreme milling cutter 4 B. EFFECT: simpler design. 1 cl, 6 dwg
