Vertical-type glass edge grinding machine - This is a vertical-type edge grinding machine for FPD coated glass substrates. The machine has been designed to stand upright to prevent water from splashing during the grinding process, thus keeping the glass surface clean and increasing the efficiency for downstream machines.
The wafer edge processing unit may be a stand alone unit or may be incorporated in existing grinding machines. The processing unit employs a plurality of tapes which are coated with differing grades of grit to sequentially polish the edge of a rotating wafer or to remove an edge bead from a processed wafer or the other substrate. The tapes are mounted on a backing block which is rotated to ...
