摘　　要：熊猫型保偏光纤(PANDA PMF)由于性能优越而得到广泛应用,但其光纤预制棒预应力深孔的加工一直是光纤生产过程中的难点.为避免传统预应力孔加工方式中的缺陷,本文采用自行研制的加工装置进行非接触式旋转超声加工,并进行了对比实验.共设计了3组光纤预制棒的深孔加工实验,得到了较优的加工方案,最终实现了直径8.3 mm、深度250 mm的预应力深孔加工.PANDA polarization maintaining fiber（ PMF） is widely used because of its superior performance. But it has always been a difficult problem to machine prestressed holes in the optical fiber preforms. To avoid the defects of traditional machining method of prestressed holes,this paper adopted noncontact rotary ultrasonic machining on self-developed machining setup. Three comparison experiments of drilling deep holes in optical fiber preforms were designed and optimal machining process was obtained.Finally,deep holes with a diameter of 8. 3 mm and a depth of 250 mm were machined successfully.
