Abstract:In order to solve the problem that the micro punch depends on manual processing because of special material，high precision and difficulty in processing，the classification，material，structure and processing development process of the micro punch are introduced.The method of machining micro punch with the CNC needle grinder is described，and the grinding steps and testing data of the three-pass punch of∮0.09 mm are analyzed taking the three-pass punch for machining the spinneret PY86-5400-0.09 as an example.It is pointed out that machining micro punch with CNC needle grinder can realize the automatic punch processing，and meet the requirements of high precision and high efficiency of the micro punch processing；the punch surface roughness Ra value can reach 0.1 μm，so the surface of the micro punch can be smooth，and the appearance quality and qualified rate of the micro punch can be greatly improve than that of manual processing，and effectively guarantee the shape and size tolerance of the spinneret micropore.
Key Words:micro punch；spinneret micropore；spinneret；CNC needle grinder；automation
