METHOD AND DEVICE FOR CUTTING FRAGILE MATERIAL PLATE

摘要

[PROBLEMS] To cut a fragile material plate in a lattice shape by using laser beam without forming extra preliminary cutting groove. [MEANS FOR SOLVING PROBLEMS] This device comprises a rotary table (1) pivotally supporting a glass pane having a lower plate member (1a), an upper plate member (1b), a spacer (1c) interposed along a center axis parallel with a first direction so as to connect the lower plate member (1a) to the upper plate member (1b), and actuators (1d) installed at the corner parts of the lower plate member (1a) and raising the corner parts of the upper plate member (1b).
