Abstract: The present invention provides a thread processing device to provide thread with various shape(direction) and size of cogs to be used in facelift operation. The device comprises a metallic processing plate with one or more grooves formed in length direction. It is preferred for the processing plate to have graduations near the groove, have a planar or arc shape, and be resistant to corrosion. In another embodiment, the processing device also includes fixing stands, which meet with the both ends of the processing plate, and a supporting plate, which is perpendicular to the fixing stands. Clamps can be used to secure the thread.
