Design and FEM Analysis of a Large Turning Table

Abstract:

Introducing the design of a large turning table. The table structure is combined with three-body, double-ring hydrostatic guide-way consists of inner and outer rings, it has the advanced features of high carrying capacity, high rigidity, high precision and good holding of the second fitting precision. Table rigidity and former six-stage modal shape are resulted by the finite element analysis, the result proves the rationality of the design. The design has been applied to the 25m vertical lathe successfully and obtained a good effect. The design solved lots of questions such as casting and machining and transport of a large table, it has reduced the cost greatly.
