Abstract

An abrasive tool includes a back plate with a first side and a second side, a plurality of segment mounts disposed in spaced relation along a majority of said first side, a plurality of abrasive segments engaged by the segment mounts, the second side being configured for attachment to a grinding machine. A method of manufacture of an abrasive tool includes providing a backing plate configured to be mounted onto a grinding machine, providing abrasive segments, and mounting the segments onto a majority of the surface of the backing plate.

Claims

1. An abrasive tool comprising:

a back plate with a first side and a second side;

a plurality of segment mounts disposed in spaced relation along a majority of said first side;

a plurality of abrasive segments engaged by said segment mounts; and

the second side configured for attachment to a grinding machine.

2. The tool of claim 1, wherein the back plate is a disc.

3. The tool of claim 1, wherein the back plate comprises glass reinforced polyester.

4. The abrasive tool of claim 1, wherein the second side comprises internal threads.

5. The abrasive tool of claim 1, wherein said mounts comprise cavities disposed in the first side of the backing plate.

6. The tool of claim 1, wherein the abrasive segments comprise grinding faces defining a plurality of shapes.

7. The tool of claim 6, wherein the shapes are selected from the group consisting of circles, squares, diamonds, octagons, wedges, and combinations thereof.

8. The tool of claim 6, wherein the grinding faces of the segments are uniform in surface area.

9. The abrasive tool of claim 1, wherein the abrasive segments are interchangeable.

10. The abrasive tool of claim 1, wherein the abrasive segments are removably secured to the backing plate.

11. The abrasive tool of claim 1, wherein the abrasive segments are comprised of materials of the group consisting of alumina, alumina zirconia, silicon carbide, CBN, diamond, and mixtures and combinations thereof.

12. The abrasive tool of claim 1, wherein the abrasive segments comprise abrasive grains within a three-dimensional bond matrix.

13. The abrasive tool of claim 1, wherein the abrasive segments are arranged in a geometric pattern.

14. The abrasive tool of claim 13, wherein the geometric pattern includes spaces between the abrasive segments.

15. The tool of claim 1, wherein the abrasive segments are integrally disposed on the back plate.

16. The tool of claim 15, wherein the abrasive segments are secured to the back plate with an adhesive.

17. The tool of claim 15, wherein said abrasive segments are threadably secured to the back plate.

18. The tool of claim 17, wherein said abrasive segments comprise threaded mandrels.

19. The tool of claim 18, wherein the threaded mandrels are secured to said segments with an adhesive.

20. The abrasive tool of claim 18, wherein threaded mandrels are molded into the abrasive segments.

21. The abrasive tool of claim 1, wherein said segments comprise threaded inserts.

22. The abrasive tool of claim 1, wherein said segments are each configured in one of a plurality of distinct sizes.

23. The abrasive tool of claim 1, wherein said segments are each configured in one of a plurality of distinct compositions.

24. The abrasive tool of claim 1, wherein the back plate is molded.

25. The abrasive tool of claim 1, wherein the back plate comprises threaded bores sized and shaped for threadably fastening the tool to the grinding machine.

26. A method of manufacture of an abrasive tool, comprising:

(a) providing a disc with a first side and a second side;

(b) providing abrasive segments;

(c) configuring the first side for attachment of abrasive segments along a majority of the first side;

(d) securing the abrasive segments along a majority of the surface area of the first side; and

(e) configuring the disc for being coupled to a grinding machine.
