Abstract

A polishing clamp for clamping a work-piece to be polished and a polishing method using the same. The polishing clamp includes a fixing-block for fixing the work-piece to be polished, a recess formed on an end surface of the fixing-block and having the same shape as the work-piece to be polished, the work-piece able to be embedded in the recess, and when the work-piece is placed in the recess, a polished surface of the work-piece to be polished is flush with the end surface of the fixing-block forming the recess. Since a portion of the work-piece to be polished that does not need polish could be prevented from contacting the polishing apparatus by means of the fixing-block when being polished, the over-wearing may not occur at edges and corners of the work-piece, improving the quality of polishing. This can improve the quality of, e.g., a light guide plate.
