This study is to examine the safety by analizing the hardness of bed and the characteristic of vibration to improve basic efficiency of machine-tool of drill-cell which is a high line center. The mistake of existing design was shown through the analysis of 3-D and structure. The purpose of this study is to prevent from a problem which may happen after this and to produce more reliable machine-tool by carrying out and finding out an adequate countermeasure for bed at the cutting position.
