摘　　要：快速点磨削(Quick-point Grinding)是一种先进的超高速磨削技术,它集成了超高速磨削、CBN超硬磨料及CNC技术,在加工轴类零件场合具有优良的性能。本文介绍了快速点磨削技术的发展现状及工艺特征,分析和研究了快速点磨削机理和材料去除机制。结果表明:砂轮的磨损机制不同于一般外圆磨削,磨削过程具有较高的绿色加工性能;通过合理控制磨削参数和磨削条件,该项技术可应用于对一些难加工材料和复杂回转表面的高质量磨削加工,由此提出了在这些领域开展应用研究的重点内容,以及推广和开发此项技术的意义。Quick-point grinding is a new type of ultra-high speed grinding technology that has integrated ultra-high speed grinding, thin super abrasive wheel and CNC turning technologies, and has many excellent performances in grinding shafts process. The technical characteristic and the machining mechanism of the tech- nique were analyzed deeply. It is shown that the point grinding zone and wear mechanism of the grinding wheel are different from conventional cylindrical grinding. Based on the study on the ultra-high strain rate in the contact layer, the process can be used to machine some difficult-to-grinding materials with high machining quality. Some kinds of complex round surfaces can be machined by controlling the point-grinding angle in CNC quick-point grinding. In addition, the green manufacturing property of the process was discussed. Furthermore, the key research issues on quick-point grinding and its importance were presented.
