  • Laser systems for drilling holes in medical devices
    Patent number: 9452494
    Abstract: Novel laser drilling systems are disclosed. The laser drilling systems are useful for drilling bore holes in medical devices, especially blind bore holes in surgical needles. The laser systems use a low power fiber seed laser to produce a high quality laser beam that is modulated and amplified, and which has precise characteristics to produce precision drilled holes.

  • Method and apparatus for making diffused cooling holes in an airfoil
    Patent number: 4808785
    Abstract: A two step process for laser drilling a hole in an airfoil and subsequently performing an EDM step to form the diffuser shaped part of the hole. Alternatively, the process may be performed by laser drilling after EDM formation of the diffuser shape. The laser drilling apparatus and the EDM apparatus each have their own computer that uses a coordinate position data base that is in common for both computers.

  • Airfoil with diffused cooling holes and method and apparatus for making the same
    Patent number: 4762464
    Abstract: Air cooling of airfoils in a gas-turbine engine is effected through holes which terminate with a diffuser formation at the airfoil surface. The invention is directed to a two-step procedure whereby a laser beam drills the holes very quickly and cost-effectively and whereby an EDM step is relied upon only to form the diffuser shape. The EDM part of the procedure thus occupies but a fraction of the time previously required, and substantial overall economy is realized by integrating these two steps, which are preferably performed in the order stated but which, if desired, may alternatively be performed by laser driling after EDM formation of the diffuser shape.
