In this paper, specification, parameter and grinding way of scribing wheel for AMLCD glass substrates scribing is introduced.

The principle of cutting and splitting glass substrates of TFT-LCD and the impacts of craft parameters on cutting quality, such as scribe-wheel angle, cut pressure, press amount are studied in this paper.

This article analyses the questions and shows the resolving methods about long-log slieer, such as the bevel cutter setting and cutting, the principle, generatrix standard formulation and the processing methods of hyperbolic-cutter.

The papaer discussed the structures, principles and functions of the ladder arrayed blades and multi-joint taper blade wheels and studied the thought and way of the design of radial cutting strips machine.
