Abstract
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.
Claims17
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.
