摘　　要：介绍了AMLCD基板玻璃切割刀轮的规格、物理参数、研磨方式,研究了研磨方式与切痕、刀轮角度与切割深度、刀轮角度与Lateral crack的比率之间的关系。研究发现在同样的切割条件下使用犁地研磨的刀轮的切痕状况最好;刀轮的角度越小,切割的深度越大,产生Lateral crack的临界压力值越小。由于切割深度可以由加大刀轮的下压量和增大切割压力来获得,因此在刀轮的选择上应首先考虑刀轮角度对Lateral crack的影响。In this paper, specification, parameter and grinding way of scribing wheel for AMLCD glass substrates scribing is introduced. The relationships between cutting trace and grinding way, scribing depth and wheel top angle, probability of lateral crack generation and wheel top angle are investigated. It has been found that the cutting trace generated by furrow grinding wheel is the best. The smaller the wheel top angle is, the deeper crack will be cut and the smaller critical pressure will be need for lateral crack generated. When scribing wheel selected, what must be taking into account first is the influence of wheel top angle to lateral crack, as the deeper crack also can be generated by large pressure.
