Standard tolerances (see: Natural diamonds, Techn. spec.) are based on the postulation that in relation to the theoretical wire elongation
1 % of deviation in Diameter or 2 % of deviation in Elongation
can be “tolerated”. Either by slippage of the wire on the drawing cones resp. rings or by the “good nature” of the material to be drawn.
But in contrary conditions this could lead to 5 % deviation in elongation. In the diameter range below 0,1 mm and with multi-wire drawing machines this is too unprecise. Fouling or breakage of the wire can occur.
