【Abstract】 This paper analyzes the damping characters of MJ7116 beds made of AGC and cause of improving dynamic stiffness through testing the dynamic behaviors of MJ7116 beds of surface grinders made of AGC and cast iron. It comes to the comparison results that the dynamic behaviour of beds made of AGC and cast iron are with similar structure, and similar weight thereby to provide a base for the use of AGC.更多还原
