【Abstract】 In this paper the application of laser hardening technology in controlling the distortion of the long shaft is discussed. The cause and influencing factors of laser hardening distortion are analysed. In the test the law of laser hardening distortion was found and applied to straighten the distorted long shafts. The test results show that laser hardening not only can control the deflection of long shaft to a very small degree but also the distorted long shaft can be straightened up to a very high accuracy.更多还原
