The Static and Dynamic Characteristics Analysis of A CNC Grinding Machine Bed Made from Artificial Granite
The machine tool bed is an important fundamental unit of the Machine tool,and its static and dynamic characteristics directly influence the precision of the Machine tools process.The precise composite B2-K3000 CNC grinding machine bed is made from artificial granite.Through entity modeling,adding the boundary conditions and stress conditions to the bed,this article analyses the static stiffness,natural frequency,vibration mode and harmonic response of the grinding machine bed,and masters the natural characteristics and preponderant natural frequency.On the basic of the beds structure characteristics and stiffness requirements,the original beds structure gets partial improvements.By increasing the number of ribs and using the cross-shaped ribs,the improved result indicates that the beds static stiffness can be enhanced obviously and the beds static and dynamic characteristics can be more excellent.
