1. A grinding member for a coffee grinding device comprising: a seat having seat threads;a top grinder set in the seat, the top grinder having a top grinding surface, a rear surface opposite the grinding surface, and a side surface between the rear surface and the grinding surface;a support made of plastic material, wherein said top grinder is laterally embraced by said plastic material forming said support, and wherein said plastic material is fixedly bound to the rear surface and the side surface of the top grinder, the support including support threads; anda bottom grinder having a bottom grinding surface facing the top grinding surface,wherein the seat threads cooperate with the support threads for adjusting a distance between the top grinder and the bottom grinder in response to rotation of the top grinder. 2. The grinding member according to claim 1, wherein the top grinder is coated laterally and on said rear surface with said plastic material forming said support. 3. The grinding member according to claim 1, wherein said top grinder and said plastic material are intimately connected by shape coupling. 4. The grinding member according to claim 1, wherein said top grinder is made of ceramic material. 5. The grinding member according to claim 1, wherein said top grinder is made of metal. 6. The grinding member according to claim 1, wherein said top grinder has a plurality of anchoring projections embedded in the plastic material of said support. 7. The grinding member according to claim 1, wherein said top grinder comprises anchoring undercuts to which said plastic material forming the support adheres intimately. 8. The grinding member according to claim 1, wherein said top grinder has a front toothing. 9. The grinding member according to claim 1, wherein said mechanical transmission member further comprises a shaft for driving the grinding member. 10. The grinding member according to claim 9, wherein said shaft is co-axial to said top grinder and extends from the rear surface opposite to the grinding surface. 11. A grinding device for grinding coffee beans, comprising at least one grinding member, said at least one grinding member comprising: a seat having seat threads;a top grinder set in the seat, the top grinder having a top grinding surface, a rear surface opposite the grinding surface, and a side surface between the rear surface and the grinding surface;a support made of plastic material, wherein said top grinder is laterally embraced by said plastic material forming said support, and wherein said plastic material is fixedly bound to the rear surface and the side surface of the top grinder, the support including support threads; anda bottom grinder having a bottom grinding surface facing the top grinding surface,wherein the seat threads cooperate with the support threads for adjusting a distance between the top grinder and the bottom grinder in response to rotation of the top grinder. 12. A coffee machine comprising a device for grinding coffee beans, the coffee machine comprising: a seat having seat threads;a first grinding member; anda second grinding member, wherein the first and second grinding members co-operate with one another, wherein at least one of said first and second grinding members comprises a top grinder set in the seat, the top grinder having a grinding surface, a rear surface opposite the grinding surface and a side surface between the rear surface and the grinding surface;a support made of plastic material, wherein said top grinder is laterally embraced by said plastic material forming said support, and wherein said plastic material is fixedly bound to the rear surface and the side surface of the top grinder, the support including support threads; anda bottom grinder having a bottom grinding surface facing the top grinding surface,wherein the seat threads cooperate with the support threads for adjusting a distance between the top grinder and the bottom grinder in response to rotation of the top grinder. 13. A method for the production of a grinding member for a grinding device, the method comprising the act of: positioning a top grinder in a die, wherein the top grinder has a grinding surface, a rear surface opposite the grinding surface, and a side surface between the rear surface and the grinding surface;molding on said top grinder a support made of plastic material, the plastic material forming a single body with said top grinder and laterally embracing said top grinder to form an intimate coupling between said top grinder and said support, wherein said plastic material is fixedly bound to rear surface and the side surface of the top grinder, the support including support threads; andforming a bottom grinder having a bottom grinding surface facing the top grinding surface,wherein the seat threads cooperate with the support threads for adjusting a distance between the top grinder and the bottom grinder in response to rotation of the top grinder. 14. The method of claim 13, wherein the molding act forms a mechanical transmission member molded with the plastic material forming said support. 15. The grinding member according to claim 1, wherein said top grinder and said plastic material are intimately connected by shape coupling. 16. The grinding member according to claim 2, wherein said top grinder is made of ceramic material. 17. The grinding member according to claim 3, wherein said top grinder is made of ceramic material. 18. The grinding member according to claim 2, wherein said top grinder is made of metal. 19. The grinding member according to claim 2, wherein said top grinder has a plurality of anchoring projections embedded in the plastic material of said support. 20. The grinding member according to claim 3, wherein said top grinder has a plurality of anchoring projections embedded in the plastic material of said support. 21. The grinding member according to claim 2, wherein said top grinder comprises anchoring undercuts to which said plastic material forming the support adheres intimately. 22. The grinding member according to claim 3, wherein said top grinder comprises anchoring undercuts to which said plastic material forming the support adheres intimately. 23. The method of claim 13, wherein the positioning act includes the acts of: inserting the top grinder in the die; andclosing the die. 24. The method of claim 23, wherein the molding act includes the acts of: melting the plastic material;injecting the molten plastic material into the closed die; andsolidifying the injected plastic material to form the support that laterally embraces the rear surface and the side surface the top grinder. 25. The grinding member according to claim 1, wherein said gear toothing is formed on a flange and is substantially co-axial to said top grinder. 26. The grinding member of claim 1, wherein the top grinder comprises a flange extending from a periphery of the top grinder to effectuate the rotation of the top grinder for adjusting the distance between the top grinder and the bottom grinder.
