1、减少金属间的摩擦，增加模具使用寿命.；
Reduce the friction between the metal, increase the mould working life.
2、允许较快的抽线速度，更大的变形量，减少加工物断损；
Allow faster speed of wire drawing, more big deformation and reduce the broken the metal loss .
3、加工完成后的钢材具有光滑均匀的表面；
the steel wire get smooth uniform surface after process finishing
4、可使钢材承受更大的变形及压缩，可以加工更多更好地标准件，如台阶螺丝或变形量较大的螺丝等。
Can give the steel ability of the more deformation and compression, can process more and better standard parts, such as steps screws or other screws with large deformations, etc.
