Introduction The precision machining of micro-hole is of great difficulty in the field of hole machining, especially when hard and brittle materials are involved.
All of these difficulties have become the bottle-neck in the field of machining hard and brittle materials.
For its special cutting mechanism, the ultrasonic vibration drill-grinding has aroused many experts’ interests in quest for machining methods of micro holes on the hard-to-machine materials.
In fact, for the small drill head, its material is different from the horn, and its equivalent diameter and mass are usually too small to be taken into account.

Effects of ZrO2 Fiber on the Mechanical Properties of Nano-ZrO2/Al2O3 Ceramic Composite1 Heyi Ge, Jianye Liu, Xianqin Hou, Huashi Liu, and Dongzhi Wang School of Material Science and Engineering University of Jinan, Jinan, Shandong Province, China mse_gehy@ujn.edu.cn Keywords: nano-zirconia, zirconia fiber, Al2O3 ceramic composite, mechanical properties.
At present using phase transformation of ZrO2 particle to toughen ceramic material is an ideal method [2].
Meanwhile, the method of fiber or whisker toughening ceramic material is very effective, which can not only improve material toughness, and in most cases can also improve material strength [3].
Experimental Materials Al2O3 powder (99 type) was supplied by Zhengzhou Smelter Manufacturing Co., Ltd.
