Method and system for finishing glass sheets

1. A method of finishing glass sheets, comprising:

forming a stack comprising alternating layers of unfinished glass sheets and spacer pads, the stack being such that there is no physical contact between any two adjacent unfinished glass sheets and outer edges of the spacer pads are recessed relative to outer edges of the unfinished glass sheets;

securing the stack by clamping the unfinished glass sheets and spacer pads together in a magnetizer fixture that applies a magnetic clamping force to the stack;

placing the stack, in its secured state, on a working surface;

supporting the stack that has been secured on a working surface;

finishing the unfinished glass sheets of the stack simultaneously while the stack is supported on the working surface, wherein after the finishing the stack comprises alternating layers of finished glass sheets and spacer pads;

forming holes in the unfinished glass sheets before or during the finishing, the holes being bounded by inner edges; and

removing the stack, in its secured state, from the working surface, wherein

the finishing comprises grinding the outer edges of the unfinished glass sheets simultaneously,

the finishing comprises polishing the inner edges simultaneously, and

the entire finishing occurs without unsecuring the stack or removing the stack from the working surface.

2. The method of claim 1 , wherein the finishing comprises removing material from rough edges of the unfinished glass sheets.

3. The method of claim 1 , wherein the grinding comprises a plurality of grinding passes, each grinding pass involving use of an abrasive material with a predetermined grit size.

4. The method of claim 3 , wherein the predetermined grit size decreases with each successive grinding pass.

5. The method of claim 1 , wherein the grinding comprises shaping the outer edges of the unfinished glass sheets.

6. The method of claim 1 , wherein the finishing further comprises polishing the outer edges of the unfinished glass sheets simultaneously.

7. The method of claim 6 , wherein the polishing comprises a plurality of polishing passes.

8. The method of claim 1 , further comprising forming slots in the outer edges of the unfinished glass sheets before or during the finishing.

9. The method of claim 1 , wherein the supporting comprises aligning the stack to a working position on the working surface and clamping the stack to the working surface at the working position.

10. The method of claim 1 , wherein the finishing occurs without altering the layer arrangement of the stack throughout the finishing.

11. The method of claim 1 , wherein the finishing comprises use of a plurality of finishing tools operated by a computer numerical control machine.

12. The method of claim 1 , further comprising separating the finished glass sheets from the spacer pads.

13. The method of claim 12 , further comprising removing the stack from the working surface and immersing the stack in a liquid medium prior to the separating.

14. A system of finishing glass sheets, comprising:

a plurality of finishing tools, each finishing tool configured to perform at least one of grinding and polishing;

a computer numerical control machine capable of operating the plurality of finishing tools;

a replaceable stack mounted on a working surface of the machine in a position to be acted on by a finishing tool operated by the machine, the replaceable stack comprising alternating layers of unfinished glass sheets and spacer pads, the replaceable stack being such that there is no physical contact between adjacent unfinished glass sheets and outer edges of the spacer pads are recessed relative to outer edges of the unfinished glass sheets; and

a magnetizer fixture capable of applying a magnetic clamping force to the replaceable stack that clamps the unfinished glass sheets and the spacer pads together, wherein

the stack is placed onto the working surface in its secured state,

the stack is removed from the working surface in its secured state

the outer edges of the unfinished glass sheets are ground simultaneously,

the inner edges are polished simultaneously, and

the grinding and polishing are conducted without unsecuring the stack or removing the stack from the working surface.

15. The system of claim 14 , wherein the spacer pads are made of conformable material.
