Tool grind fixture

Abstract

A tool sharpening fixture is provided which is particularly suited for sharpening rotary cutting tools. The tool sharpening fixture comprises a housing having a throughbore and a bushing rotatably mounted in the housing throughbore and having an eccentric axial bore formed through its. An elongated cylindrical member is inserted through the bushing eccentric bore so that the elongated member extends outwardly from each end of the housing. The cutting tool to be sharpened is removably mounted at one end of the elongated member while the opposite end of the elongated member can be grasped by the hand of the user. An indexing ring is secured to the bushing and locks the elongated member to the bushing in at least two predetermined rotational positions. Typically, the number of indexing positions is the same as the number of cutting edges on the tool to be sharpened. A stop ring is also rotatably mounted to the housing and lockable at any desired rotational position. The stop ring includes two stop members which cooperate with a stop tab on the bushing to limit the rotation of the bushing and the elongated cylindrical member between two preselected rotational positions.
