Lathe precise machining method for ultrathin-wall-thickness metal pipe part

Abstract

The invention discloses a lathe precise machining method for an ultrathin-wall-thickness metal pipe part. The ratio of the pipe diameter to the wall thickness of the related part exceeds 100; and in the machining process, an appropriate clamping tool and a reasonable machining sequence are selected to reduce overall deformation of a workpiece in the machining process, and in the machining steps, the appropriate feed cutting quantity and a cutter matched with the feed cutting quantity are selected to reduce heat of the cutter in the cutting process, and stress exerted on the workpiece in the cutting process is reduced. According to the method, stress deformation caused by the fact that external force is exerted on the workpiece in the turning machining process can be effectively controlled, and therefore internal stress generated in the part cutting process can be fully released; the higher size and form and location tolerance requirement of the ultrathin-wall-thickness metal pipe part in the machining process is met, and the machined part is small in size deformation and has the long-term stability. The method has the common referential meaning in machining and manufacturing of the small-type ultrathin-wall-thickness metal pipe part which is urgently required in the special field.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a lathe precision processing method for ultra-thin wall thickness metal pipe parts. Background technique [0002] Thin-walled tube parts are widely used in various industries of national production, especially in special fields such as aerospace and military, such as space optical systems, cryogenic refrigerators and Dewar and other systems and equipment, metal thin-walled tubes Class parts are widely used and play a very critical role. In the metal cutting and manufacturing industry, the processing of thin-walled pipe parts has always been a difficult point. The outstanding performance is low processing yield, large deformation after processing, and poor stability. Such problems have always plagued the related processing and manufacturing industries. One of the puzzles. Special application fields such as aerospace and military put forward very strict requiremen...

Problems solved by technology

In the metal cutting and manufacturing industry, the processing of thin-walled pipe parts has always been a difficult point. The outstanding performance is low processing yield, large deformation after processing, and poor stability. Such problems have always plagued the related processing and manufacturing industries. one of the puzzles

Regrettably, as of now, there are not many targeted lathe precision machining methods for such ultra-thin wall-thick metal pipe parts with a pipe diameter-to-wall thickness ratio of more than 100 in China.
