摘　　要：对蓝宝石、晶体硅等贵重硬脆晶体加工的要求越来越高,如切割效率和表面加工质量,而且工件的尺寸也逐渐增大,需要设计一种高效的切割设备并探索新的切割方式。本研究建立了一种旋转切割模型,通过旋转工件进行切割,保持一种单点接触式的切割,提高环线金刚石线锯机的切割效率。利用自制的环形金刚石线锯机做切割实验,结果表明,相对于常规固定式的切割法,切割效率至少提高了50%,并且提高了表面加工质量。As higher standard required for the processing of precious hard brittle crystal such as sapphire and crystal silicon, for excample, the cutting efficiency and surface pro- cessing quality： as well as the increasing size of the workpiece, a cutting equipment of：high efficiency must be designed and new cutting mechod should be developed. A ;rotary cut- ting model has been established by this research. Under this cutting technique, single point contact cutting has been kept through the rotation of the workpiece, hence the cut- ting efficiency of the diamond wire saw machine has been improved. A cutting experiment has been done for the self-made diamond wire saw machine. The result shows that the cutting efficiency has been improved by 50% compared to the conventional cutting method and the surface processing quality has also been improved.
