摘要
为了提高镗削加工精度,摆脱加工设备精度条件的限制,在对镗削加工误差和气浮轴承进行理论分析的基础上,设计并使用气浮镗杆进行镗孔试验。实验结果表明:使用气浮镗杆镗孔可以使圆度达到1.09μm,粗糙度达到0.233μm。在镗削加工中使用气浮镗杆能极大提高加工精度,为精密镗削加工提供了一条有效途径。
In order to improve the accuracy of boring, and get rid of the accuracy of processing equipment conditions, pneumatic boring bar is designed and used for boring test based on the theoretic analysis of the machining error and the pneumatic bearing. The experimental results indicate that the boring of the pneumatic boring bar can make the roundness reach 1.09μm and the roughness reach 0.233μm. In the boring process using pneumatic boring bar can improve the processing accuracy, and the pneumatic boring bar processing technology for precision boring machining provides an effective way.
