| 20090185876 | GLASS WORKING APPARATUS AND GLASS WORKING METHOD USING THE SAME - A glass working apparatus a casing, in which a rotating mechanism and an oscillating unit are installed. The rotating mechanism has a shaft rotatably mounted in the casing. The oscillating unit is connected with the shaft such that the oscillating unit is rotatable with the shaft. A glass cutting tool is connected to the oscillating unit, such that the glass cutting tool can be driven to rotate by the rotating mechanism through the oscillating unit and/or driven to oscillate by the oscillating unit for working on a glass workpiece. | 07-23-2009 |
| 20090185874 | GLASS CUTTING TOOL - A glass cutting tool includes a cutter body provided at a bottom portion thereof with a hole-cutting portion. The hole-cutting portion has a circular cross section and a recessed hole recessed inwardly from a bottom end thereof, such that the contact area between the hole-cutting portion and a workpiece of glass panel can be minimized when the hole-cutting portion is rotated to work on the glass panel, thereby avoiding cracking of the glass panel during working and lowering the defect rate and processing cost. | 07-23-2009 |
