Patent number: 7666067Abstract: 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.Type: GrantFiled: June 10, 2005Date of Patent: February 23, 2010Assignee: TJ Utveckling ABInventor: Torgny Jansson

Publication number: 20080274678Abstract: A grinding jig for use in the grinding of a straight edge woodworking tool on the peripheral surface of a rotating grindstone in a grinding machine. The grinding machine has a cylindrical support bar parallel with the rotation axis of the grindstone. The jig includes a base, which is parallel with the support bar and is intended for slidable and rotational mounting on the support bar, and a clamp, wherein the tool is attached between the base and the clamp. The grinding jig has a support surface on the base for supporting the face of the tool opposite its bevel.Type: ApplicationFiled: May 1, 2008Publication date: November 6, 2008Applicant: TJ Utveckling ABInventor: Torgny Jansson

Publication number: 20080020685Abstract: A truing tool for a grindstone (1) is intended for attachment to a universal support (3) in the form of a cylindrical rod of a grinding machine in parallel with the rotation axis of the grindstone. It has—in a holder (12) therefore—a cutting tip (13) for truing engagement with the grindstone. The holder (12) is movably connected to a yoke (10)—to be attached to the universal support (3)—by a feeding rod (14), which is rotatably supported by the yoke (10) and is in engagement with a threaded bore in the holder (12), for its movement in relation to the yoke transversely of the grindstone (1).Type: ApplicationFiled: July 9, 2007Publication date: January 24, 2008Applicant: TJ Utveckling ABInventor: Torgny Jansson
