METHOD OF SCRIBING ON BRITTLE MATERIAL, SCRIBE HEAD, AND SCRIBING APPARATUS WITH THE SCRIBE HEAD

摘要

Is obtained that the vertical crack forming the scribe lines crossing each other significantly deeper in the cutting step of the method after the cross-scribing, a scribing method capable of cutting a glass plate as a scribe line. Through the scribing head body 2 to travel to the brittle material is a tip holder 4 parallel to shaft 9, and the brittle material surface the shaft is provided to rotate about the 9 central axis of the addition, the tip holder 4, the cutter wheel chip 5 is brittle in a scribe head 1 through a rotating shaft 13 parallel to the material surface are provided to rotate around the central axis of the rotary shaft 13 is made, the shaft 9 on the face the brittle material by driving the phase brittle material to the rear with respect to the cutter wheel chip 5 to form a scribe line.
