A body-positioning system for accurately adjusting a position of a ceramic shaped body, said system comprising:

• a centering table for placing a ceramic shaped body;
• a plurality of chucking units at least one of which comprising at least one body-pushing member mounted on at least one shaft and each chucking body comprising a plurality of holes for receiving said shaft for detachably mounting said body-pushing member on said chucking body, wherein said body-pushing member is for detachable mounting at a first of said plurality of holes in a single horizontal row in the chucking body for contacting a first shaped ceramic body and for detachable mounting in a second hole for contacting a second shaped ceramic body different from said first shaped ceramic body;
• at least one path of movement for a ceramic shaped body and at least one said chucking unit on each lateral side of each path;
• and
• a drive unit for moving the chucking units toward/away from a ceramic shaped body on the centering table, wherein
• the drive unit makes the plurality of chucking units approach and push a ceramic shaped body on the centering table while controlling positions and speeds of the chucking units, thereby adjusting the position of the ceramic shaped body on the centering table while conveying substantially no destructive shock to the ceramic shaped body.
