Research on 40Cr Steel for High-Speed Spinde Laser Transformation Hardening Technics
40Cr steel is a common quenched axis steel with high, tough, and plastic cooperation. However, quenched steel for high speed spindle rigidity and resistance is not satisfactory. It is easy wear at axle journals and affacts the precision. 40Cr steel with normalized one has been hardened by laser. To find a good technics for high-speed spindle by laser surface hardening, to improve 40Cr steels hardness and wear resistance.Analyse kinds of samples which are harden by different technics. Diameter of facula 7 mm, laser power 1600 W, speed of scan 15 mm/s is the best parameters. Then microstructures analysis, rigidity measurement are carried out. The result: the sample with the technics is the best for high-speed spind machining and milling. The hardness of hypo-surface layers hardness is 2.04 times of the conventional heat treatment, and it is wearable.
