METHOD AND DEVICE FOR CUTTING FRAGILE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a cutting method for efficiently and certainly cutting a fragile material along a cutting scheduled line for a relatively short time, and a cutting device therefor.

SOLUTION: In the cutting method for continuously and locally heating the plate-shaped fragile material G along the cutting scheduled line L and cutting the locally heated part 3a of the fragile material G continuously and locally to cut the same, the locally heated part 3a is locally cooled while cooling the both lateral sides of the locally heated part 3a of the fragile material G continuously. The cutting device of the fragile material G is equipped with a local heating means for heating the plate-shaped fragile material G along the cutting scheduled line L continuously and locally, and a local cooling means 4 for cooling the locally heated part 3a continuously and locally and also equipped with a pair of side part cooling means 5 for continuously cooling both side parts of the locally heated part 3a of the fragile material G.
