Dynamic Characteristics Analysis of Precision Linear Rolling Guide CNC Grinding Machine Tool’s Bed

Bed is a main component of a large precision linear rolling guide CNC grinding machine tool Its dynamic characteristics impact on machine tool’s machining precision and stability directly. In this paper, boundary conditions on the bed of a machine tool factory’s production are analyzed. By using FEA method, the bed finite element models for dynamic analysis model are established and calculated. It provides guidance in investigating the effect factors of machining precision, the machine tool’s structure optimization and error compensation.
