The improvement of machine tool accuracy is the most important for recent highly advanced manufacturing technology. And highly sophisticated design techniques are required to realize ultra-accurate machine tools such as a diamond turning machine. In this study, alumina ceramic is introduced as a material for a machine tool bed to overcome many problems such as thermal deformation and bed rigidity, that are important for accurate machine tool design. A design methodology of light weight machine tool construction is also investigated for realizing easy-to-control thermal behavior and for improving the vibration performance. As a result, a developed diamond cutting machine with a ceramic bed shows good performance, surface roughness, temperature stability and vibration characteristics.
