The importance of bed structure of internal grinder

Mar 23, 2020

Among all the components of the internal grinder, the bed is a very important structure, which plays a role in supporting the work piece and connecting the worktable, bridge plate and other key parts. The design size and layout of the bed structure determine its dynamic characteristics, such as static and dynamic stiffness and modal shape of the structure. The dynamic characteristics of the bed structure are closely related to the performance of the machine tool. Improving the dynamic characteristics of the bed parts is of great significance to ensure the machining accuracy of the machine tool. Because of the unreasonable design of the bed structure and the lack of dynamic stiffness of the bed structure, it will produce a large vibration in the working state, which will cause a large relative amplitude between the work piece and the cutter, thus reducing the machining accuracy of the machine. Therefore, the dynamic characteristics of the bed are closely related to its structural size, shape
