A research on precision grinding of the line shaped surface has carried on, and the research is base on saucer wheel on numerical control surface grinder. Summarized the common grinding technique of line shaped surface. Then, based on numerical control generating machining, principle, and the two axes of the surface grinder worked interlocked, grind the line shaped surface by utilizing the saucer wheel or the sloped edge wheel. Have analyzed the grinding mechanism of the numerical control generating grinding, surface compacting mechanism and wheel truing, in addition, have analyzed the influencing factors of the profile accuracy such as wheel fixing error, wheel form error, grinding feed distance and numerical system, etc. Finally, have developed a new numerical control generating grinding technique of line shaped surface.
