摘　　要：珩磨技术凭借加工精度高、材料去除率大的优势,广泛应用于精密孔加工。航空发动机广泛采用高温合金、钛合金、不锈钢等航空难加工材料,其难加工性降低了珩磨加工的材料去除及误差修正能力,限制了珩磨工艺在航空发动机精密孔加工中的进一步应用。为突破难加工材料珩磨工艺瓶颈,对难加工材料珩磨工艺特性进行分析,并以高效精密珩磨工艺及工具为切入点,归纳了航空难加工材料精密孔高效珩磨技术现状,并对其发展趋势进行了预测。Honing technology is widely used in precision hole processing as a result of its high machining accuracy and material removal rate. However, conventional honing hasn＇t fully contributed its advantages in honing difficult-to-cut materials, such as superalloy, titanium alloy, stainless steel, which are widely used in aeroengines. To break through the bottlenecks in honing technology of difficult-to-cut materials, firstly, an analysis of process behavior of honing difficult-tocut materials is made; secondly, the research of high efficiency and precision honing difficult-to-cut materials is summarized from aspects of honing process and tools; finally, the tendency of high efficiency and precision honing difficult-to-cut materials is predicted.
