The Spindle Static Characteristic Analysis of HTC3250µn NC Machine Tool

Abstract:

The analysis of spindle static stiffness is particularly important. The concept of spindle stiffness is introduced. Based on software ANSYS, the finite element analysis model of simplified spindle is established. Two equivalent forms of bearings are discussed and the analysis results are compared. The stress distribution nephogram of spindle is given. The research indicates that using spring-damper element instead of bearings is more suitable and the machining accuracy mainly depends on the stiffness rather than strength.
