摘要：PROBLEM TO BE SOLVED: To provide a chamfering device for liquid crystal cell substrate equipped with a mechanism for controlling the chamfering condition corresponding to the state of a cross section and a mechanism for removing cullets generated by chamfering from a liquid crystal cell substrate. SOLUTION: An image at the terminal part of a liquid crystal cell substrate 1 is picked up by a line sensor camera 7 installed at the upper part of the liquid crystal cell substrate, the state of the cut terminal part is discriminated by a discrimination part, and the number of rotations of a grindstone 6 and the speed of an adsorption stage 4 are controlled into optimum conditions by a control part. The chamfering work is performed while supplying cutting water and sucking the substrate with a vacuum box 11. After the end of working, the liquid crystal cell substrate is washed by rotary cleaning brushes.
