Abstract

The invention relates to a processing method for a hollow thin-walled elongated shaft. By adopting the processing equipment of a numerically controlled lathe and a numerically controlled cylindrical grinder, the process route is rationally optimized, the processing parameters are reasonably given, and an inner hole boring tool with a machine clamping tool is used, and Carbide 90° cylindrical turning tool, innovative clamping method for parts processing, provides a processing method for the processing of hollow thin-walled slender shaft parts, and realizes the processing of hollow thin-walled slender shaft parts .

Description

Processing method of hollow thin-walled elongated shaft Technical field [0001] The present invention relates to a processing method, especially a processing method of a hollow thin-walled elongated shaft. Background technique Hollow thin-walled shaft is a kind of part commonly used in aviation field, and its material is generally 9310 steel, and the structural characteristic of part Point: the length is longer, greater than 4500mm, the wall is very thin, the average wall thickness is 1.2mm, the wall thickness difference is within 0.05mm, and the end is set With splines, the requirements for the shape and position tolerance of the shaft diameter of the parts are very strict. Greater than 0.01mm. Due to the super long shaft diameter of the part, the reference span of the two shaft diameters will be very far, so that the part is added During the machining process, there will be alignment errors of the long axis diameter, and it is difficult to guarantee the wall thicknes...
