Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a tool used for processing a compressor shell. Background Art

[0002] The compressor housing is a shell structure used to accommodate the internal components of the compressor. It plays a role in fixing and protecting the internal components of the compressor, and can also prevent external substances such as dust and sewage from entering the compressor, while also effectively reducing the noise of the compressor.
