  • Laser hardened steel cutting rule
    Patent number: 6335506
    Abstract: A hardened steel cutting rule obtained by the process of a first step of applying a first laser beam having a first intensity and focused to a first focal point to a selected surface area of a steel cutting rule, and a second step of applying a second laser beam having a second intensity and focused to a second focal point to the selected surface area. The hardened steel cutting rule may also be obtained by the process of applying a laser beam absorbent substance to a selected surface area of a steel cutting rule, applying a first laser beam having a first intensity and focused to a first focal point to the selected surface area of the steel cutting rule, and applying a second laser beam having a second intensity and focused to a second focal point to the selected surface area.

  • Laser hardened steel cutting rule
    Publication number: 20010015348
    Abstract: The invention relates to surface hardening of steel workpieces using laser beams and more particularly to laser hardening steel cutting rules. The method comprises applying a first laser beam of a first intensity and focused to a first focal point to a selected surface area of the metal workpart and subsequently applying a second laser beam having a second intensity and focused to a second focal point to the selected surface area. Application of the first laser beam heat treats the selected surface area to a predetermined depth, thereby increasing the surface hardness. Application of the second laser beam relieves internal stresses produced by the heat treating while retaining the increased hardness.
