Abstract: Crankshaft is the core part of pump body of compressor. With the miniaturization, high efficiency and high quality of refrigeration compressor, the requirements for pump body parts become more stringent and the manufacturing process of crankshaft becomes more complicated. By analysing the material selection of crankshaft, local strengthening treatment, analysis of poor machining factors and surface treatment, etc. In order to avoid influencing factors reasonably and improve the quality of crankshaft during the manufacturing process.

Key words: Crankshaft processing, Grinding process, Process method, Surface treatment, Phosphating, Molybdenization
