Abstract

The invention discloses a machining method and a machining device of a cobalt-base superalloy thin-walled sleeve part, and belongs to the technical field of machining. The machining device provided bythe invention comprises a clamp assembly and a mandrel. A workpiece is supported through the clamp assembly and the mandrel, the internal cylindrical surface and the external cylindrical surface of apipeline billet are machined, in the machining process, the pipeline billet is not prone to deformation, the machined workpiece inner and outer diameter wall thickness difference is small, the shapeprecision is high, and the workpiece surface roughness is high.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method and a processing device for cobalt-based superalloy thin-wall sleeve parts. Background technique [0002] Cobalt-based superalloys have medium durable strength, excellent oxidation resistance and satisfactory forming, welding and other process properties, and are often used in the defense industry. The workpiece material made of cobalt-based superalloy has high hardness and high strength, which is particularly easy to damage the knife, especially its high-temperature hardness and strength retention are very good, which will bring great challenges to the hardness, strength and wear resistance of the tool ( The tool cost is also difficult to control); the thermal conductivity is not high, and good cooling is required, which is a typical difficult-to-machine material. [0003] Since cobalt-based superalloy workpieces are often used in the defense i...
