The energy absorptivity and hardness of knife surface are obviously increased using graphite coating during laser thermal treatment for high speed steel knife.
采用石墨涂层，对高速钢刀片进行了激光热处理，显著地提高了刀片表面的能量吸收率和硬度。

While achieved precision which the knife mold manufacture needed to reduce greatly has stirred up the laser scalpel mold's manufacture cost.
在达到刀模制作所需要的精度的同时大大降低了激光刀模的制作成本。

The pulse laser cutting is a new working process, which can make the seam to contact better with the body of knife, so the strength, life and rigidity of the die board have risen.
