介绍一种新研制的能把超声振动和金刚石磨粒磨削结合在一起的特种金刚石钻头。阐述了该钻头的钻削机理及设计制作过程。试验表明，该钻头是钻削工程陶瓷、宝石等硬脆材料的理想工具。
A newly developed special diamond drill bit that combines ultrasonic vibration with diamond abrasive grinding is introduced. The drilling mechanism and design process of the drill bit are expounded. Tests show that the drill is an ideal tool for drilling hard-brittle materials such as engineering ceramics and precious stones.
