A device for grinding a cutting tool uses a rotatable grindstone and a tool holder for mounting the cutting tool. The device guides the tool, mounted in the tool holder, along an intended plane, which is tangential to a peripheral surface of the rotatable grindstone, using a practically linear contact between the rotatable grindstone and the cutting tool. By moving the tool holder, with the mounted cutting tool, along the intended plane, this plane is transferred to an unbevelled side of the cutting tool.

The invention claimed is: 1. A device for sharpening a profiled cutting tool, the device comprising: a grinding base, wherein the grinding base is attached to a support device mounted on a grinding machine, the support device including two opposed support members extending from the grinding machine
The invention claimed is: 1. A device for sharpening a profiled cutting tool, the device comprising: a grinding base, wherein the grinding base is attached to a support device mounted on a grinding machine, the support device including two opposed support members extending from the grinding machine, whereby the grinding base is removably attached to the support members at two opposing ends of the grinding base, the two opposing ends of the grinding base connected by two additional opposing members that straddle the periphery of a grinding stone when the grinding base is mounted to the support members, wherein the two additional members of the grinding base comprise guiding means with guiding surfaces, and a tool holder for holding a cutting tool, wherein the guiding surfaces are adapted to guide the tool holder in an intended plane tangential to the peripheral face of the grinding stone, and the tool holder has surfaces for interacting with the guiding surfaces of the guiding means of the grinding base. 2. The device according to claim 1, further comprising: micro-adjust means on the support device for accurately adjusting the position of the cutting tool relative to the grinding machine. 3. The device according to claim 1, further comprising: micro-adjust means on the support device for accurately adjusting the position of the guiding means relative to the grinding machine. 4. The device according to claim 2, wherein the micro-adjust means comprises a threaded leg of universal supports of the support device and a screw nut screwed on to said leg. 5. The device according to claim 4, wherein the screw nut of the micro-adjust means to be screwed on to the threaded legs of the universal support are provided with a scale for simplifying accurate adjustment of the grinding depth. 6. The device according to claim 2, wherein a projection of the grinding base forms an angle with the plane of a horizontal mounted universal support which is smaller then 45 degrees, resulting in a change ration between the adjustment of said universal support and the change in grinding depth. 7. The device according to claim 3, wherein the micro-adjust means comprises a threaded leg of universal supports of the support device and a screw nut screwed on to said leg. 8. The device according to claim 7, wherein the screw nut of the micro-adjust means to be screwed on to the threaded legs of the universal support are provided with a scale for simplifying accurate adjustment of the grinding depth. 9. The device according to claim 3, wherein a projection of the grinding base forms an angle with the plane of a horizontal mounted universal support which is smaller then 45 degrees, resulting in a change ration between the adjustment of said universal support and the change in grinding depth. 10. The device according to claim 1, wherein the shape of the guiding means of the grinding base is planer. 11. The device according to claim 1, wherein the grinding base is provided with an adjustable arm to ensure that the grinding base is fully supported on the support device of the grinding machine, irrespective of manufacturing tolerances of universal supports. 12. The device according to claim 1, wherein the guiding means is provided with a slick material for simplifying the movement of the tool holder. 13. The device according to claim 12, wherein the slick material is PTFE of Teflon®. 14. The device according to claim 1, wherein the tool holder is provided with a magnet for retaining the cutting tool on the tool holder. 15. The device according to claim 1, wherein the tool holder is provided with a plurality of bores where spring pins can be mounted for securing one of a variety of different cutting tools on the tool holder. 16. The device according to claim 1, wherein the tool holder is provided with vertical sidewalls which protect a cutting edge of the cutting tool during the grinding operation. 17. The device according to claim 1, wherein the tool holder is provided with a protruding edge or rim for retaining the tool on a tool mount.
