NOISE POWER-SPECTRAL ANALYSIS AND THE METHOD FOR REDUCING THE NOISE OF THE MC 6140 TYPE LATHE MAIN DRIVING SYSTEM

Zhang Zulin (Guangdong Mechanical Institute) Li Shaobin (South China University of Technology)  
This paper describes time series analysis modeling and spectrum analysis method and their application on noise diagnosis for the new designed MC 6140 type lathe model.According to the analysis and research for the possible noise source in the lathe,this paper proposes a method for improving the structural design and manufcture process.As a result, it has reduced the noise of the lathe from the original 84db ( A ) to less than 80db ( A ) which has reached the export lathe standard of China.
