Abstract

Tool for rolling threads into the surface of a workpiece (7) comprises a movable roll block (1) and a fixed roll block (2), each having cutting (3, 5) and calibrating (4, 6) parts in which the cutting surfaces are inclined at an angle (alpha) to the calibrating surfaces. The length (L3) of the cutting surface of the movable block (1) is 0.1D-2.0D, where D is the nominal diameter of the thread to be rolled. The length (L6) of the calibrating surface of the fixed block (2) is 3.0D-5.0D. The length (L5) of the cutting surface of the fixed block is 0.5 (L2-L6) where L2 is the length of the roll block (2) and L6 the length of the calibrating surface (6) of the fixed block. @(5pp Dwg.No.1/1)@
