| Abstract: | In order to solve the technical problem in the process of high-lead ball-nut grinding,the method of micro-hard turning the spiral groove by the layered envelope method is presented in this paper.A diamond-shaped indexable insert with a circular arc at the tip of the parallel nut axis is mounted on the cutter shaft.The enveloping turning points are generated by normal section offset and coordinate transformation.The nut raceway is processed layer by layer based on the enveloping turning points.In the end,taking the processing of the high-lead ball-nut as an example.The results show that this method can meet the machining precision requirements of the high-lead ball-nut and have great value in practice. |
