High air tightness and little plastic deformation are required for the bonding surface of 1,000,000 accelerator disks that:compose the next generation high-energy linear collider. In this paper, the optimal diamond turning conditions are discussed to fabricated such disks efficiently. The leak tests were carried out using OFHC copper disks machined under various conditions and the vacuum level of disks was measured. The surface topography of disks also was measured and the amount of the plastic deformation was calculated from the plastic flow pressure of the copper. The optimal diamond turning conditions are derived by using concept of information amount in consideration of the vacuum level, the amount of the plastic deformation and the material removal rate.
