Abstract
This paper presents a new manufacturing technology for machine tool beds, which is composed of high stiffness epoxy concrete structure faces and lower cost steel fiber cement concrete core. After steel fiber cement concrete core is poured, epoxy concrete structure faces are poured. The technology is first applied in manufacturing of CKA6150 CNC lathe bed. Through comparing with cast iron machine tool bed and epoxy concrete machine tool bed, it is estimated by five elements value green estimate theory. The result demonstrates that composite concrete machine tool bed not only has high characteristic and lower energy cost but also meets requirements of green manufacturing.
