A straight wire is not always drawn by the single crystal die because the hole of die is not composed of isotroopic face by the frictional characterics of the various crystallographic orientations. By means of tilting the die, the wires have the highly inhibitory actions against the bending drawn wire. In these cases, the wires are unified in the distribution of hardness on the skin layer of drawn wire, and the distribution of frictional force ratios on the die hole surface for rubbing by thinner wire. Then, from the diagrams of die holes on the developed chart of diamond crystal sphere represented by the restricted Mercator projection, it is forecasted that the die having the entrance crystal plane on the {1O0}, {110} or {111} plan does not curve the drawn wire. The experlmental results by these dies came true as was expected.
