20080306432 | CUTTING APPARATUS WITH ULTRASONIC TRANSDUCER - A cutting apparatus includes a blade mount supporting a first ultrasonic transducer for imparting ultrasonic vibrations to a cutting blade. The blade mount includes an annular flange having a grip surface on an outer circumferential side surface thereof for gripping the cutting blade, a first ultrasonic transducer housing portion for housing the first ultrasonic transducer, and a hollow cylindrical mount boss having a fitting hole fitting over the spindle. The annular flange has a plurality of through holes defined therein between the first ultrasonic transducer housing portion and the mount boss. A blade grip flange has a fitting hole fitted over the mount boss, a grip surface on an outer circumferential side surface thereof for gripping the cutting blade, a second ultrasonic transducer housing portion for housing a second ultrasonic transducer, and a plurality of through holes defined therein between the second ultrasonic transducer housing portion and the fitting hole. | 12-11-2008 |

20150259235 | PLATE-SHAPED OBJECT PROCESSING METHOD - A plate-shaped object processing method forms a through hole of a desired shape in a plate-shaped object. The method includes a through hole contour forming step of performing laser processing within the plate-shaped object along a contour of the through hole to be formed, by positioning, within the plate-shaped object, a focal point of a pulsed laser beam of a wavelength capable of passing through the plate-shaped object. The beam is applied along the contour of the through hole to be formed by a pulsed laser beam irradiation unit including a condenser applying the laser beams. A through hole is formed by breaking the laser-processed contour of the through hole and forming the through hole by positioning an ultrasonic transducer of an ultrasonic wave applying unit in correspondence with the contour of the through hole to be formed, and applying an ultrasonic wave. | 09-17-2015 |
