Abstract: Here is a cross orthogonal ceramic parts composed of three sections of SiC ceramic pipe,two intersecting curved surfaces are formed at the both ends of the parts.The design requirements need to meet precision fit and achieve sealing at the both intersecting curved surfaces by grinding.To ensure the quality of grinding process and to meet precision fit and the sealing technology requirements at the both intersecting curved surfaces.In present work,design and manufacture of cross-intersectional ceramic pipes had been systematically investigated.Lapping finishing technics of pipe intersection line also had been discussed.Special clamp tool and differential screw fine-tuning mechanism were designed and fabricated in order to reach the required sealability.The results showed that accuracy and quality of crossed ceramic pipe met the accepted engineering requirement after lapping process.

Key words: ceramic, lapping finish, intersection-curved surface, clamp tool design, differential screw
