日本东京都立大学工学部的古川勇二教授研究组,开发了在主要构造材料上使用氧化铝陶瓷的平面型超精密加工机。陶瓷做为机床的构造材料,不但可以节约金属材料,而且还可以发挥金属材料所不具备的陶瓷特点。一是陶瓷硬不变形,并且比重小,重量轻。这样用在立柱等上就不会因弯曲产生加工误差,而保证高精度加工。其次是与金属比较,陶瓷不产生热变形,利于进行高精度加工。此外,陶瓷不生锈、不
Japan’s Tokyo Metropolitan University Department of Engineering Professor Furukawa Yong 2 research team has developed the main structural materials using alumina ceramic planar ultra-precision machining machine. Ceramic as a machine tool construction materials, not only can save metal materials, but also can play the ceramic material does not have the characteristics of ceramics. First, the ceramic is not deformed, and the proportion of small, light weight. This will not be used in the column and so on due to bending processing error, and ensure high-precision machining. The second is compared with the metal, ceramic does not produce thermal deformation, which will help high-precision machining. In addition, the ceramic does not rust, no
