Experimental Research on Self-Alignment Design Principle of a Large-Scale Precise Machine Bed

Abstract

In order to eliminate thermal deformation of large-scale precise machine tools caused by ambient temperature change, self-alignment design principle and key points are proposed for a large-scale precise machine tools, Self-alignment simulation experiment, machined parts experiment and compared results for self-alignment rail grinder and other similar products are analysed, the present analysis show that self-alignment rail grinder has many advangtages of good precision, straightness stability.
