32面金刚石切工/32 sides diamond cut

                       相较于普通16面的加工，增加一倍的抛光面到32面，增加砧面的正圆度以减少砧面边缘的应力。

                       Compared to the ordinary 16 surface processing，double the polishing surface to 32 surface，

                       increase the positive roundness of the anvil face to reduce the stress at the edge of the anvil face.
