The invention relates to a method of making a grinding disk, comprising the steps of: providing a cap; providing an abrasive part; placing the cap on the abrasive part to form an assembly; holding the assembly and injecting a molding material into a space between the cap and the abrasive part and into the abrasive part to bond the cap and the abrasive part. A grinding disk made by the method is also disclosed.

1. A method of making a grinding disk, comprising the steps of: providing a cap;providing an abrasive part;placing the cap on the abrasive part to form an assembly;holding the assembly and injecting a molding material into a space between the cap and the abrasive part and into the abrasive part to bond the cap and the abrasive part. 2. The method of claim 1, wherein the cap is made by injection molding. 3. The method of claim 1, wherein the abrasive part is made of non-woven materials. 4. The method of claim 1, wherein the abrasive part is substantially disk-shaped and has a central hole, and wherein the cap has a substantially disk-shaped body with a through hole, and an encircled wall extending from the bottom of the cap body and surrounding the through hole, the encircled wall having a first pair of opposite slots so that when the cap is placed on the abrasive part, the encircled wall fits the central hole of the abrasive part, and the molding material is injected through the through hole and the slots and is distributed over a contact region of the cap and the abrasive part and into the abrasive part to bond the cap and the abrasive part. 5. The method of claim 4, wherein the cap further comprises an outer circumferential edge extending downward and having a bottom side, and two guide walls each extending from the bottom of the cap body along the outside of the respective slot of the first pair of opposite slots and having a bottom side the bottom sides of the two guide walls being at least flush with the bottom side of the outer circumferential edge so that when the cap is placed on the abrasive part, the bottom side of the outer circumferential edge contacts a top surface of the abrasive part, and the bottom sides of the two guide walls at least contact the top surface of the abrasive part. 6. The method of claim 4, wherein the encircled wall further has a second pair of opposite slots for the molding material to pass through. 7. The method of claim 3, wherein, after the step of injecting a molding material to bond the cap and the abrasive part, the molding material forms a holding part between the cap and the abrasive part, said holding part having a shaft hole. 8. The method of claim 7, wherein the shaft hole is threaded. 9. The method of claim 4, wherein, after the step of injecting a molding material to bond the cap and the abrasive part, the molding material forms a holding part between the cap and the abrasive part, said holding part having a shaft hole. 10. The method of claim 9, wherein the shaft hole is threaded. 11. The method of claim 6, wherein the length of the first pair of opposite slots is substantially the same as that of the second pair of opposite slots. 12. A grinding disk made by the method of claim 1. 13. A grinding disk, comprising: an abrasive part; anda cap provided on the abrasive part;wherein the abrasive part and the cap are bonded by injecting a molding material into a space between the cap and the abrasive part and into the abrasive part. 14. The grinding disk of claim 13, wherein the cap is made by injection molding. 15. The grinding disk of claim 13, wherein the abrasive part is made of non-woven materials. 16. The grinding disk of claim 13, wherein the abrasive part is substantially disk-shaped and has a central hole, and wherein the cap has a substantially disk-shaped body with a through hole, and an encircled wall extending from the bottom of the cap body and surrounding the through hole, the encircled wall having a first pair of opposite slots, the encircled wall fitting to the central hole of the abrasive part and the molding material being injected through the through hole and the slots and distributed over a contact region of the cap and the abrasive part and into the abrasive part to bond the cap and the abrasive part. 17. The grinding disk of claim 16, wherein the cap further comprises an outer circumferential edge extending downward and having a bottom side, and two guide walls each extending from the bottom of the cap body along the outside of the respective slot of the first pair of opposite slots and having a bottom side, the bottom sides of the two guide walls being at least flush with the bottom side of the outer circumferential edge, the bottom side of the outer circumferential edge contacting a top surface of the abrasive part, and the bottom sides of the two guide walls at least contacting the top surface of the abrasive part. 18. The grinding disk of claim 16, wherein the encircled wall further has a second pair of opposite slots for the molding material to pass through. 19. The grinding disk of claim 15, wherein the molding material forms a holding part between the cap and the abrasive part, said holding part having a shaft hole. 20. The grinding disk of claim 19, wherein the shaft hole is threaded. 21. The grinding disk of claim 16, wherein the molding material forms a holding part between the cap and the abrasive part, said holding part having a shaft hole. 22. The grinding disk of claim 21, wherein the shaft hole is threaded. 23. The grinding disk of claim 18, wherein the length of the first pair of opposite slots is substantially the same as that of the second pair of opposite slots.
