The paper introduces the laser surface hardening processing with 5 KW CNC CO$-2$/ laser for Cam Shaft made of 45 steel. The results show that spiral scanning matching with adaptable technological parameters and water cooling achieve remarkable hardenability with less deformation, which satisfy the requirements demanded by manufacturer, simplify the manufacturing technology. The advantage of laser surface hardening is very remarkable.
